Captain Owen Strand

Profession: Firefighter

Played By: Rob Lowe

Appearances: 9-1-1: Lone Star

Owen is a former New York firefighter who relocated to Austin, Texas with his son, TK Strand to rebuild the 126 after all but one of its crew were killed in an accident. He developed lung cancer due to working during 9/11, but goes into full remission in Season 2.

---

• A Father to His Men: Is deeply involved in taking care of his squad.
  Owen: I have three commitments to my people: everybody who clocks in will also clock out, everybody gets a fair shake, and no one—and I mean no one—gets left behind when it comes to skincare.
• Action Dad: Has been a firefighter for over 20 years and now works with his son.
• Agent Peacock: Definitively a straight man but is very into his physical appearance, obsessed with hair/skin care products, is keen on interior design/antiques and high end amenities, etc.
• The Captain: Previously of the 252 Manhattan Fire House in New York. He is currently this to the 126 Austin Fire House.
• Conspiracy Theorist: The team is stunned in season 3 to realize Owen truly believes in aliens contacting Earth for years, from how they gave Eisenhower advanced technology to literally laughing at the idea the Egyptians built the pyramids.
• Da Chief: Was this to the 252 Manhattan Fire House. Since moving to Austin, he's now this to the 126 Austin Fire House.
• Disappeared Dad: Owen initially thought his own father was this when he was younger. The truth is actually sadder; he used to be a more caring figure, but after Owen’s little brother, Tyler, died, he emotionally checked out. He barely even put up a fight against his wife taking Owen with her to New York, and later started another family that Owen meets at his deathbed.
• Experienced Protagonist: Owen has been a firefighter for over 20 years. He is also the only firefighter to rebuild an entire fire house from scratch, which makes him the perfect one to rebuild the 126 Austin Fire House.
• First-Episode Twist: Is told he has lung cancer that was caused by working at 9/11’s ground zero.
• First-Name Basis: After TK and Carlos become a couple, Owen tries to get Carlos to call him by his first name when they’re off the job, with mixed results.
• Good Parents: Is this to his son, TK. He also wanted to be this to his ex-wife's second child Jonah even after he realized he wasn't the biological father.
• Hair-Trigger Temper: Owen’s temper has gotten him in trouble numerous times, most notably placing him in court-ordered anger management therapy after punching Billy Tyson. Even after completion he still can’t keep it under control. After the events of “Impulse Control” (3.14) Owen seeks help for this.
• Hidden Depths:
  • Surprises Michelle with his skills in line dancing.
  • Has a real in-depth knowledge of skin care.
• Honor Before Reason: After getting suspended for punching Billy in the face, he is given the option of writing a formal apology for doing so, and he'd be gladly reinstated as a Captain, even if not as Captain of the 126. Owen though, tired of fighting and considering Billy solely at fault, keeps this fact from everyone and decides to go off the grid for several months. When Marjan learns about this from Billy, she is rightfully pissed and calls Owen out on it, with Owen eventually swallowing his pride and signing the apology.
• I Call It "Vera": Names his blender “Marlon Blendo” after the method actor Marlon Brando.
• I Let Gwen Stacy Die: His very first case of Survivor Guilt occurred when he lived in LA as a child— Owen’s younger brother Tyler was his Gwen Stacy, who drowned when the two snuck to the pier to go surfing.
• Incurable Cough of Death: Owen's first symptom of his lung cancer is a cough, which he thinks is only the flu until his doctor tells him otherwise.
• In Touch with His Feminine Side: He's rather particular about his hair and is very worried about what will happen to it when he starts cancer treatment. He's also very big on his skin care routine, offering to teach Paul how to get a complexion like his own.
• Lost Lenore: Despite the fact that they were divorced and no longer romantically involved, he's never fully gotten over the sudden death of his first wife Gwyn, often seeing her in his dreams and visions.
• Mistaken for Gay: Zoe thinks he's gay in "Studs" (1.05) because he knows so much on skin treatments.
• Papa Wolf: Is quite protective of his son and his squad.
• Parent-Child Team: Works with his son in the same firehouse, until TK applies to become The Medic in “Everyone and their Brother” (2.06).
• Really Gets Around: After being divorced twice, Owen has had his share of flings and “girlfriends of the season”. It gets to the point that in season 3, he’s been nicknamed “One-Night Strand.”
• Reasonable Authority Figure: He's a very fair, reasonable commanding officer.
• Secretly Dying: Found out he has lung cancer and hasn't told his son. He’s currently in remission, despite a relapse scare in “A Bright And Cloudless Morning” (3.18).
• Shirtless Scene: Is seen shirtless in the changing room of the fire house in the "Pilot" (1.01)
• Sole Survivor: 20 years prior to the "Pilot" (1.01), Owen was the only one of his Manhattan firehouse to survive the 9/11 attack.
• Survivor Guilt: He has felt a lot of guilt for surviving 9/11 while so many, including his entire firehouse crew, didn't. When he was diagnosed with cancer, he actually felt relief since he felt that the universe was finally evening the score. He gets another dose of this when Tim is killed right in front of him and he lives because he was about a foot to the side.
• Team Dad: Besides being TK’s father and captain, he actively tries to treat his subordinates with as much respect and kindness as possible. He clearly trusts his team because of their skillsets, not because of their identities.
• The Topic of Cancer: Owen is told in the "Pilot" (1.01) that he has lung cancer; the first three seasons see him undergoing treatment and struggling to balance it with his firefighting duties and prideful nature.
• Tragic Keepsake: Owen keeps a melted part of the South Tower from the 9/11 attack on his desk as a reminder. He finally throws it out to move past the guilt in “A Bright and Cloudless Morning” (3.18).
• White Male Lead: Lampshaded, as Owen asks why Austin FD is headhunting him when they're trying to improve diversity, especially considering that it was so bad the federal government had to intercede. He's told that, for this house, knowing how to rebuild a firehouse from scratch is the single most important qualification. It's also implied that his hiring practices in New York were similar to those he showed in Austin.

Judson "Judd" Ryder

Judson "Judd" Ryder

Profession: Firefighter

Played By: Jim Parrack

Appearances: 9-1-1: Lone Star

A firefighter and husband to one of Austin’s dispatch callers, he is the sole survivor of 126's original crew and deals with PTSD throughout the course of season 1.

---

• Action Dad: Becomes one in “Push” (3.04) when Charlie is born.
• Anger Born of Worry: Very prone to this.
  • In "Texas Proud" (1.03), he gets into a fight with TK because the latter deliberately disobeyed his orders on a mission. At the end of the episode, Judd makes up with him by saying that the only reason he even got mad was because he was scared for him and Marjan.
  • “A House Divided” (4.16) sees him and Tommy experience a Plot-Mandated Friendship Failure when Tommy stays behind in a burning paper mill to try and save one of the trapped workers. Though they get him out just before it explodes, the worker’s death leaves Tommy shaken; the ensuing conflict of interest Judd faces when writing up the incident report causes him to frustratedly remind her about Charles’ death, which earns him her cold shoulder for a while.
• The Atoner: Was involved in a car accident as a minor that left his friend dead; despite both of them being equally involved, he blames himself. He later makes amends with the boy's mother.
  • This comes back in full force when Wyatt enters his life and reveals their relation, which prompts Judd to involve himself in the boy’s life to make up for his absence even when he had no way of knowing of his existence. By the end of season 4, it comes to a head when, while training to become a firefighter, Wyatt gets critically injured in a freak accident to the point of needing intensive physical rehab.
• Big Brother Instinct: Once he grows close to the rest of the team, he becomes quite protective of them.
• Brutal Honesty: For better or worse, he minces no words and takes no craps when voicing his opinion.
• Crisis of Faith: After the death of his original team, Judd doesn't see the point of going back to church with Grace.
• Happily Married: Is married to Grace in a happy and lovely relationship.
• Huge Guy, Tiny Girl: There is a major height difference between him and his much shorter wife.
• Like Father, Unlike Son: Starting from “The ATX Files” (3.06), this becomes a recurring issue for him as he makes himself a part of Wyatt’s life.
• Number Two: Gradually settles into being a right-hand captain to Owen, even occasionally taking over for him in the latter’s absence.
• Papa Wolf: In Season 3, his Big Brother Instinct grows into this for his son, Wyatt, and daughter Charlie.
• Platonic Life-Partners: With Tommy, the two have been friends for a very long time, and she helped him when he was first dating Grace. He and Grace later name their child after her late husband.
• Secret-Keeper: Judd is this for Owen, as he is the only one that Owen has told about the cancer.
• Shell-Shocked Veteran: 6 months after the 126 firehouse tragedy, Judd is clearly suffering from PTSD.
• Sole Survivor: Judd is one of only two survivors of the original 126 Fire House.
• There Are No Therapists: Averted in "Yee-Haw" (1.02), where Judd is attempting to see a therapist, with Grace, to help deal with his PTSD from the original 126 tragedy. He also passes on some of the advice he received from said therapy sessions.
• Would Hurt a Child: Smacks a teenager in "Hold the Line" (2.03), in order to prevent him from going unconscious from blood loss.

Marjan Marwani

Marjan Marwani

Profession: Firefighter/Paramedic

Played By: Natacha Karam

Appearances: 9-1-1: Lone Star

A firefighter/paramedic who is also a devout Muslim, recruited due to her fearlessness and skills. Has a online profile known as #FireFox which often go viral with videos of her and the 126's rescues.

---

• Action Girl: During Marjan's interview, her Establishing Character Moment sees her jumping off a bridge into water in order to rescue two civilians trapped in a submerged car. From that point on, she’s shown to be the most combat-proficient of the 126 firefighters.
• Affectionate Nickname: The 126 crew sometimes calls her “Marj” for short. And when she was a child, her parents used to call her their “little Mouse”.
• Alliterative Name: Marjan Marwani.
• Attention Whore:
  • Has no problem being filmed when making a rescue and gaining millions of views over social media. Even debating with Paul as to who should rappel down a building to save a person, Paul points out she only wants to do it because a news crew had just turned up.
  • Justifiably Averted, however when her hijab comes off in "Texas Proud" (1.03) since showing hair for practicing Muslim women is forbidden; once she’s freed from a corn silo, she's less worried about nearly getting crushed to death than about the moment being caught on camera.
  • She attempts to use this productively at the start of season 3, filming herself standing in protest in front of the blown-out 126 firehouse to rally support against its demolition— and her recurring efforts exasperate the construction workers on-site.
• Big Sister Instinct: Acts as an “intimidating” older sister to Mateo, and is practically a second sister to Paul.
• Instant Web Hit: Naturally, as a major Instagram personality. However, she’s still vulnerable to people using this status against her if they feel she’s failed them.
  • In the "Pilot" (1.01), the Instagram video of Marjan's water rescue has over 6 million likes, it gets 3 million more in one night after Cardi B reposts the video.
  • In "Texas Proud" (1.03), a video of her hijab coming off goes viral, getting over 6 million views on Instagram within a day.
  • Weaponized in "A Little Help From My Friends" (2.10), when she undercuts some obnoxious teens' intent to virally mock a young woman's injuries by posting her own video of them gloating about said injuries. Given how many followers she has as "Firefox", the clip of the teens' callousness becomes vastly more popular than the cruel clip they'd tried to disseminate.
  • In “Slow Burn” (2.11), after Marjan fails to rescue a couple from a dangling truck, the grieving widow posts her own "The Reason You Suck" Speech on Instagram and triggers a string of hateful messages that furthers Marjan’s guilt.
  • In “Human Resources” (4.05), a married couple from “The New Hot Mess” (4.02) threatens to file a lawsuit against the fire department for Marjan calling the wife who refused to leave “a crazy lady” when trying to evacuate her from her mobile home. When she and Owen meet with them in person, they give her an ultimatum that threatens her own principles: post a public apology and ask her social media followers to donate money to their GoFundMe page for purchasing a new home, or deal with the lawsuit. Not helping matters is the department refusing to deal with said lawsuit, which leaves Marjan to decide between the two bad options. Marjan ultimately decides to post a video that seems like an apology, but is instead a call-out against the Fire Department and the couple for this stunt, while declaring she's resigning from the 126 due to feeling she can't save others if she's going to be unjustly punished by a department that cares more about PR than it does about saving lives, to the point of willfully entertaining extortion.
• Long Hair Is Feminine: During the few times Marjan isn’t wearing her hijab, her hair is shown to be long enough to reach her hips.
• The Medic: In addition to being a firefighter, she is also a paramedic (though not on Tommy’s team).
• Not So Similar: She faces a (slightly) similar situation to Owen and Billy’s conflict in “Human Resources” (4.05). When Paul, Nancy and Owen call out her Honor Before Reason in refusing to issue a public apology to a couple threatening to file a lawsuit against her as being no different from Owen refusing to apologize to Billy despite her issue with that, Marjan makes clear that, unlike Owen, she actually is sorry for what she did, but that's why what they're demanding hurts so much— the couple’s blatant extortion attempt would have her abuse the trust of her followers and highlights how the AFD is more willing to condone said extortion if only to avoid some bad PR, compared to Owen only needing to sign a formal apology that didn't even need to be sincere, but instead deciding to go off the grid due to his own issues.
• Put on a Bus: Ends up temporarily leaving the 126 after the above events of “Human Resources” (4.05). The rest of the 126 bid her a tearful goodbye as she promises to keep in touch before riding off on Owen's, now her motorcycle…
  • The Bus Came Back: …and she returns after the lawsuit is dropped and she finds out she is meant to be rescuing people after saving a woman from her abusive boyfriend on her road trip.
• Savvy Guy, Energetic Girl: The gregarious Energetic Girl to Paul’s more analytical Savvy Guy.
• Survivor Guilt: In “Road Kill” (4.09), she’s revealed to harbor guilt about surviving an SUV accident that killed her childhood friend and his parents, to the point that she hallucinates the memory of it and a younger version of herself when the above-mentioned boyfriend runs her off the road and tries to kill her.
• The Squadette: The only girl in the 126 Fire House.
• Token Religious Teammate: She's a devout Muslim and is very proud of being one.
• Twofer Token Minority: She is a Middle Eastern, devoutly Muslim woman.
• Thrill Seeker: Loves to get into the heart of the danger, even it means risking her life.

Paul Strickland

Paul Strickland

Profession: Firefighter

Played By: Brian Michael Smith

Appearances: 9-1-1: Lone Star

A firefighter from Chicago who is also a trans man, specializes in damage assessment and has a talent for spotting details no one else does.

---

• Awesome by Analysis: Observing and catching details about various situations and people is his specialty. So far:
  • In the "Pilot" (1.01), during his interview, a video is shown that he was able to uncover an arsonist in a crowd of people, with little to no other information other than how that person was acting on the scene.
  • Also in the pilot, he is able to determine how a mother crashed her car and where the doors would have come off, just by viewing the site.
  • In "Yee-Haw" (1.02), he is able to determine who and how poisoned the office worker within a few minutes.
  • "Back in the Saddle" (2.01) has him quickly determining who was shooting the crossbow by looking through the open windows, noticing that the culprit is the only one with a window next to an air conditioner.
  • When helping Owen to clear Kendra’s name for her ex-husband Brett’s mysterious death in “Tongues Out” (4.14), he not only figures out how Brett accidentally poisoned himself with a potent insecticide, but also connects and re-contextualizes the previous episode’s emergency^note In “Open” (4.13), said ex-husband had gotten his arm stuck under Kendra’s car rotating her tires to the murder investigation, determining that the real culprit was Brett himself.
• Big Brother Instinct: He acts like a big brother to Mateo, who is the youngest member of their team.
• Cool Big Bro: Fills the role alongside Judd. He (specifically, his dead gender) also used to be one to his sister Naomi, until his transition drove her away.
• Don't You Dare Pity Me!: When Paul is diagnosed with Brugada syndrome in “The Bird” (3.09) triggered from experiencing hypothermia in the ice storm, he adamantly refuses to have a pacemaker installed in him, even when he’s reminded by his cardiologist and Marjan that any of his firefighting activities could trigger a fatal heart attack. After he does experience one, waking up to find that Marjan saved his life and allowed the pacemaker to be installed, he’s livid at her perceived betrayal for the rest of his recovery. But, they make up at the end of “Parental Guidance” (3.10).
• Had to Be Sharp: His Awesome by Analysis talent was initially a defense mechanism to survive the mean streets, until he applied it productively in the field.
• Rescue Romance: In "Studs" (1.05), Paul helps Josie after a fight at a strip club, they strike a flirty texting relationship and end up going on a date. They only have one date after Paul reveals that he's trans.
• Savvy Guy, Energetic Girl: In his friendship with Marjan, he’s the analytical Savvy Guy to her more outgoing and sociable Energetic Girl.
• The Smart Guy: Because of how Paul grew up, he has a strong ability to read people and situations.
• Supreme Chef: Is able to make a wide variety of food to feed the multi-cultured 126 team members.
• Trans Relationship Troubles: Has run into a few people who have issues with his identity as a trans man, both romantic and familial.
  • In "Studs" (1.05), Paul is worried about going on a date with Josie, due to the fact that she doesn't know that he's trans and he's afraid of how she'll react. The date goes well and Josie really likes Paul, but after Paul reveals that he's trans, Josie admits unfortunately that him being trans is something that she can't get past. She is quite apologetic about how she reacted the night before after their date.
  • In a familial version, his younger sister Naomi was so thrown by Paul’s transition that she distanced herself from him as much as he, according to her memory, did to her when he experienced gender dysphoria; she eventually reconciles with him in “Everyone and their Brother” (2.06).
  • Later in season 4, while reconnecting with an old classmate-turned-HR-worker named Asha, he gets uncomfortable at her reminiscing at their school memories since it reminds him of his dead identity.
• Twofer Token Minority: He is a Black and transgender man.

Mateo Chavez

Mateo Chavez

Profession: Firefighter

Played By: Julian Works

Appearances: 9-1-1: Lone Star

Mateo is a rookie firefighter who is trying to prove that he is worthy of being one. After failing the written exam five times despite showing incredible intelligence, Capt. Strand clocks him as Dyslexic and recruits him, the crew later helping him pass the verbal equivalent and becomes a Probationary Firefighter.

---

• The Atoner: It's revealed that Mateo serves as a firefighter, at least partially, to atone for a prank that got out of hand as a teen that led to his school being partially burned down. His cousin Marvin took the blame for it, which eventually made him turn to crime. This has long haunted Mateo and after Marvin's death it comes to a head where Mateo nearly tries to turn himself in but is convinced by Owen to instead devote his life, and his life-saving actions, to Marvin's memory instead.
• The Baby of the Bunch: He's the youngest member of Firehouse 126, and it shows. While the others tease him a lot, it's very obvious that it's only because they're fond of him.
  • However, this is inverted with his roommates. He's the youngest, but he is the only functional adult in his housing situation.
• Book Dumb: Averted, as the reason he failed the firefighter written test 4 times is revealed to be undiagnosed severe dyslexia in "With Friends Like These" (1.06).
• The Cobbler's Children Have No Shoes: Mateo is a firefighter whose apartment blows up in "A Little Help From My Friends" (2.10) because his roommates have no concept of fire safety, deciding to tamper with a gas line while incense was burning.
• Eager Rookie: Really wants to prove that he's worthy to be called a firefighter, and has the least experience out of all the new hires. No longer the case as of season 3, after the 126 firehouse is rebuilt and reopened.
• Embarrassing Tattoo: He got himself a tattoo, which due to his dyslexia, said "Guardian Angle" rather than "Guardian Angel." Luckily, Marjan is able to take him to another tattoo parlor to get it fixed so it says "Guardian" and the rest of the phrase is hidden by flames.
• Foolish Sibling, Responsible Sibling: Though an uncharacteristically drunken dream sequence, it’s very heavily implied in “Double Trouble” (4.11) that before his cousin Marvin became an on-off criminal in the main series, he was still prone to shenanigans, but used to be more straight-laced. Ironically enough, Mateo was the more foolish cousin, frequently skipping school, then tagging and accidentally burning it down, which Marvin took responsibility for.
• Height Angst: Experiences this at first in his burgeoning relationship with Nancy, more out of a desire to protect her from mockery than out of personal humiliation. They manage to talk it out and move past it.
• The Illegal: He's a DREAMer, an undocumented immigrant who's given temporary residency as a minor. He even stresses in “With Friends Like These” (1.06) that he’s only got a certain number of times he can try at passing the firefighters’ written exam and keep his job, otherwise he’ll risk facing deportation.
• In-Series Nickname: "Probie", because he's the newest firefighter. After he becomes a full-on firefighter, the nickname is dropped.
• The Keet: During downtimes, he’s one of the most earnest and outgoing guys in the group.
• Let's Get Dangerous!: In the season 2 finale, Mateo is stuck working a temporary assignment with the 129 and sent out to pick up lunch instead of responding to calls. This results in him being on scene when a plane crashes during a sandstorm, forcing him to take command of a mass casualty event by himself. By the time crews respond to the scene, they find that Mateo already rescued many of the victims and organized them into a makeshift triage area.
• My Greatest Failure: In “Double Trouble” (4.11), it’s revealed that not being able to help his cousin Marvin long-distance is this for Mateo. Later, a remorseful Mateo admits to Owen that as a teenager, he inadvertently set his school on fire and Marvin took the blame for it, which led to him becoming a criminal in LA. When Marvin is then killed after being released from jail, this devastates Mateo to the point that he almost decides to turn himself in to APD for it before Owen talks him out of doing so.
• New Meat: While the other fire fighters all have worked in other fire houses, Mateo has only been through Fire School.
• Shirtless Scene: Is seen shirtless in the changing room of the firehouse in the "Pilot" (1.01).
• Team Dad: While The Baby of the Bunch with the 126, "A Little Help From My Friends" (2.10) shows he's this with his roommates. He's implied to be the only responsible and mature one, even before they blow up the place due to tampering with the gas lines while drunk.
  • In “Parental Guidance” (3.10), Mateo supports Captain Tatum like a son would for an aging father to the extent that he even briefly switches houses in order to help his former captain and get him help whether he felt he needed it or not.
  • He also shows shades of this with Marjan when he and the 126 see her off in “Human Resources” (4.05).
• Tiny Guy, Huge Girl: His dynamic with Nancy, which leads to a bit of Height Angst on his part till they talk it out.
• Took a Level in Badass: In the second season finale, he takes control of an entire city block in the aftermath of the sandstorm, setting up stations for people to go to for medical assistance when backup arrives, guiding people to safety, and even helping people out of a stalled elevator. His performance is so impressive that Owen states that, once the firehouse is rebuilt, his probation period will be over and he'll be a full-fledged firefighter.

Station 121

Captain Billy Tyson

Captain Billy Tyson

Profession: Firefighter

Played By: Billy Burke

Appearances: 9-1-1: Lone Star

A former firefighter for the 126 who plots to take Owen's job as captain of the 126.

---

• Bitch in Sheep's Clothing: He befriends Owen, then tries to get him fired from his position at the 126. After getting struck by lightning, he decides to drop the animosity, even if he and Owen don't like each other still.
• The Captain: Is this to the 121 Fire House.
• Heel–Face Revolving Door: His relationship with Owen is....complicated, to say the least. His initial conflict with Owen ends in them having a grudging respect for each other, and he later returns with them on more friendly terms. He serves as a Red Herring for the Serial Arsonist plotline, seeming to betray Owen but this actually being part of a plan to catch the real culprit. But by the season finale, he's taken the Deputy Chief position that Owen turned down and states his intention to keep the 126 closed. While the 126 sees this as a betrayal, his reasoning is kind of hard to argue, and he does end up helping Grace deliver her baby, and doesn't protest the 126 reopening once they have the funds and even forms a truce with Owen by the end.
• Jerkass Has a Point: While the 126 is understandably pissed at his decision to keep the 126 station closed and getting Owen suspended, his arguments In-Universe are hard to refute. There wasn't enough money in the budget to keep it open, a budget that Owen himself had compiled, and he was perfectly willing to reinstate Owen had he actually signed a formal apology like he was offered, but Owen's stubborn refusal to do so and hiding said fact from the others stopped him from doing so, something Marjan calls Owen out on.
• Jerk with a Heart of Gold: In season 1, Billy barely hid his envy and discontent with Owen’s arrival, his similar swagger, and wildly different approach to hiring practices and the workspace— to say nothing of acting somewhat entitled when he rants at Owen about how he’s practically desecrated the place beyond recognition. However, he’s a fundamentally decent, if prideful man at heart: his reasoning for the two main “hateful” actions he takes can be interpreted as having genuine concern (namely informing Owen’s superiors about his lung cancer, and shutting down the 126 station after the arson attack) for Owen and his crew. And at the start of season 3, he also stuck by a heavily pregnant Grace’s side when they were both stranded in the ice storm until they’re found by Judd, Owen, and Tommy.
• Kick the Dog: When Owen offers to let him have the 126 as long as he keeps the current crew, Billy makes it clear he intends to fire them all. Especially his son.
• Laser-Guided Karma: He tries to take Owen's job, and accuses him of being reckless. When it starts raining on the golf course, he mocks Owen for being afraid of a little weather, then follows it up by vaguely threatening the rest of the 126 members (minus Judd), especially TK. He gets struck by lightning not long after, and is critically injured.
• Lifesaving Misfortune: When he was in the 126, he was diagnosed with thyroid cancer and was on leave to get treatment. Thus he was spared the fate of the rest of the 126.
• Politically Incorrect Villain: He skirts around things a bit, but is particularly disdainful of the minority members of the 126. He fully intends to fire them while attempting to fire Owen, but takes the time to sardonically ask if he's pronouncing Marjan’s surname correctly and mocks Chavez for his learning disability. It's largely dropped later on, as he begins treating the others with respect even if they don't like him.
• Sole Survivor: Thanks to his sick leave, he and Judd are the only two survivors from the original 126 crew.
• Villainy-Free Villain: He might be a redneck piece of work to his friends and coworkers, but the only “villainous” thing he actually did in his drive to reclaim the 126 was tell Owen's superiors about his cancer, which is not only true, but a matter of genuine concern as most people really couldn't do the job while undergoing chemotherapy. Even when refusing to reopen the 126, as he points out, the budget can't afford to keep it open, a budget that Owen put together at that, and the only reason Billy even got the position of Deputy Chief is because Owen turned it down. After Marjan’s online fundraiser earns enough money to reopen the 126, he has no objections and gladly supports it.

However, after the pandemic hit, her husband's restaurant took a huge financial hit, forcing her to take back up her uniform. She is old friends with Judd and Grace.

---

• Berserk Button: Disrespecting or using the subject of Charles against her is a surefire way to get on the wrong end of her wrath, specially after he dies.
• The Captain / Team Mom: Of the EMS 126 crew.
• Experienced Protagonist: It's stated that she was quite the respected paramedic eight years ago and even mentored Michelle Blake back in the day. As "Back in the Saddle" (2.01) proves, her absence from the job hasn’t rusted her skills one bit.

• The Medic: She’s the original, and then returning, captain of the Emergency Medical Services team at the 126.

• Platonic Life-Partners: With Judd. They've been friends for a very long time, she helped him when he was first interested in Grace, and later on Judd and Grace named their child after her late husband.
• Savvy Guy, Energetic Girl: Gender-Inverted with her and Charlie. She’s more down-to-earth, firm and practical; he’s optimistic, fun-loving, and patient.
• Twofer Token Minority: Afro-Latina and a woman.

Nancy Gillian

Nancy Gillian

Profession: Paramedic

Played By: Brianna Baker

Appearances: 9-1-1: Lone Star

A paramedic who is also a member of Michelle Blake's EMS crew.

---

• Achilles' Heel: In “Red vs. Blue”, it’s clear that she has the build for baseball, but not the experience of playing the game… which causes her to strike out often.
• Ambiguously Bi: When discussing Mateo's Height Angst she says she's always been taller than all of her love interests, including the ones in "six inch heels", earning a raised eyebrow from the rest of the 126.
• Ascended Extra: She gets considerably more screentime and character depth in season two.
• Defrosting Ice Queen: Towards TK when he joins the paramedic squad, as she's still grieving her partner Tim. She gradually warms up to him over the latter half of the season.
• Fire-Forged Friends: With TK. They start out on frosty terms as she's grieving her former partner and feels TK is out of line in his efforts to both replace Tim and impress Tommy but as they work alongside each other and he makes a genuine effort to reach out to her they become quite close.
• Flat Character: In the first season, she and Tim serve no character purpose or role other than filling out Captain Blake's paramedic team. This changes by the second season.
• Jerk with a Heart of Gold: Can be abrasive and standoffish when she’s in a bad mood, but it doesn’t negate her caring side to her teammates and dedication to saving people’s lives.
• No Good Deed Goes Unpunished: “Riddle of the Sphynx” (3.13) sees Nancy successfully revive a patient who collapsed in her home… only for the patient to angrily kick her and the paramedics out and file a lawsuit. Justified, as said woman was suffering from stomach cancer and was on a DNR order that Nancy purposely ignored.
• Tiny Guy, Huge Girl: Her dynamic with Mateo, leading to some Height Angst on his part till they talk it out in “Spring Cleaning” (3x17).

T.K. Strand

Tyler Kennedy "T.K." Strand

Profession: Firefighter/Paramedic

Played By: Ronen Rubinstein

Appearances: 9-1-1: Lone Star

Owen's son and firefighter in the 126, who is gay, as well as a recovering opioid addict. His relapse and overdose following his boyfriend leaving him for another man prompts Owen to move them to Texas.

---

• Bar Brawl: Is involved in one in "Texas Proud" (1.03). Played With in that he wasn't even drunk; he was just depressed and wanted to stop feeling "numb."
• Dark and Troubled Past: Has a history of substance abuse from when he lived in New York.
• Dead Guy Junior: He was named after Owen’s late brother who died when they were kids.
• Extremely Protective Child: He has Owen's back just as much as Owen has his.
  • In the second-season premiere, he's ready to go at someone who is shooting at Owen and Tommy with a fire axe before being stopped by Judd.
  • In “The Big Heat” (2.12), he’s quick to lash out at even Carlos when the latter comes to the firehouse to break the news of Owen’s arrest.
  • This later evolves to Big Brother Instinct, as he instantly and fully considers his half-brother Jonah as part of the family after he’s born, and part of his grief about losing Gwyn extends to Jonah not knowing his mother.
• Functional Addict: In “In the Unlikely Event of an Emergency” (3.08), TK insisted to Gwyn during a flashback that he genuinely kept his drug addiction from interfering in his firefighting duties. She didn’t buy it for even a second— though it’s implied that at the time, he was starting to lose this functionality.
• Hidden Depths:
  • He’s familiar with a few Hebrew prayers, including the Mourner’s Kiddash, despite not attending synagogue for several years.
  • He also has a love of various lizards— which hilariously often clashes against Carlos’ dislike of them.
• In the Blood: Having grown up with Owen’s influence as a firefighter, TK frequently works with him both in the New York and Austin departments. Subverted in Season 2, when he comes to realize that he functions much better as The Medic than as a firefighter, so he applies to and eventually joins Tommy's team.
• Locked Out of the Loop: Doesn't know about his father's cancer at least until "Act of God" (1.04).
• The Medic: Applies to be part of Tommy's paramedic team in "Everyone and Their Brother" (2.06).
• Missing Mom: In the first season, TK's mom Gwyn is only mentioned as being Owen's first wife. This changes when she’s introduced in the second season, until her death in mid-season three.
• Mr. Fanservice: He's muscled as all hell and gets quite a few Shirtless Scenes to show his very defined body.
  • In “Thin Ice” (3.02), it becomes Fan Disservice after he develops near-fatal hypothermia and collapses shortly after Tommy and Nancy finds and helps him up.
• Near-Death Experience: Much akin to Buck, TK’s had more than one brush with death both on and off the job.
  • The first half of the “Pilot” (1.01) is something of an Establishing Character Moment, where after going through a drug overdose (the reason for which is seen below), he ends up unresponsive until Owen and his fire team in New York break into his apartment to resuscitate him. A later interaction between father and son later implies that it isn’t the first time that he’s almost died this way.
  • “Monster Within” (1.08) sees him getting shot in the chest by an elderly couple’s grandson seconds after he busts in their door, and ending up in a temporary coma from the blood loss.
  • In “Thin Ice” (3.02), he falls through a frozen lake while pulling out a trapped child in an ice storm, causing him to develop severe hypothermia that puts him in another coma after he’s rescued.
• Not Good with Rejection: After getting dumped by his first boyfriend, Alex, TK in a depressed state overdoses on what is presumably opioid pills. Justified, as he was about to propose when he finds out.
• Official Couple: After much teasing in the first season, he starts a romance with Carlos in “Austin, We Have A Problem” (1.10). As of “A Bright and Cloudless Morning” (3.18), they’re now fiancées. And as of “In Sickness and in Health” (4.18), they’re Happily Married.
• Off the Wagon: Overdoses when his first boyfriend, Alex, tells T.K that he's in love with someone else and breaks up with him, right after T.K. proposes to him. He ends up having a few more close calls in season 3, nearly stealing some vials of fentanyl after learning his mother was killed and getting drugged by a stalker targeting Owen.
• Only Known by Their Nickname: He’s very rarely addressed by his full name, with the only two people who have being Gwyn and Carlos.
• Parent-Child Team: Works with his dad in the same firehouse. The team is broken up once he switches to being The Medic.
• Recovered Addict: Swears to his dad that he hasn't touched a single pill after he went through drug rehab thanks to Gwyn’s intervention. However, the rejection from his first boyfriend causes him to relapse, which kickstarts his and Owen’s move to Texas.
• Romantic Wingman:
  • TK is this to Paul in "Studs" (1.05), hyping him up and helping to convince Paul to go on a date with Josie.
  • He and Carlos later serve as Marjan’s dating chaperones in “Swipe Left” (4.12) when she meets with a “nerdy” Muslim man.
• Ship Tease: With Carlos. They become official at the end of the first season, get engaged at the end of the third season, and become Happily Married at the end of the fourth season.
• Shirtless Scene: If the aforementioned fan service description wasn’t enough.
  • Is seen working out shirtless in the "Pilot" (1.01).
  • Is seen making out shirtless with Carlos quite a few times in the first two seasons, starting from "Yee-Haw" (1.02).
• Straight Gay: He's very proud of his masculinity and sexuality.
• Tropaholics Anonymous: T.K. is attending NA meetings after his forced overdose in “Negative Space” (3.12).
• Troubled, but Cute: TK’s more of a Nice Guy than most examples of the trope, but this trait is prominent in the first season, since he’s recovering from his substance relapse and heartbreak, on top of adjusting to living in a new state and learning about Owen’s lung cancer.
• Understanding Boyfriend: It’s a little bumpy after Alex, but part of TK’s character development and relationship with Carlos involves becoming this.
  • In “Friends with Benefits” (2.04), he’s understandably pissed about Carlos not introducing him as his boyfriend to his parents when they’re at a farmers’ market, but comes around after a pep talk from Owen and Gwyn about feeling safe.
  • Two seasons later, when Carlos reveals that he forgot about having a secret marriage to Iris, he takes the news in stride, only expressing his anxiety about the divorce process conflicting with reserving a date for their marriage, and meeting Iris for the first time.
    • In the aftermath of Gabriel’s murder in “In Sickness and in Health” (4.18), he decides to temporarily postpone his and Carlos’ wedding, so that the latter has time to grieve his father.
• Vomit Indiscretion Shot: In the “Pilot” (1.01), after Owen and his team successfully resuscitates T.K. from his substance relapse.

Former

Captain Michelle Blake

Michelle Blake

Profession: Paramedic

Played By: Liv Tyler

Appearances: 9-1-1: Lone Star

Michelle is a paramedic, and Emergency Medical Services (EMS) captain. She is also trying to locate her missing sister Iris, who has been missing for three years.

---

• Always Someone Better: Michelle had this relationship with her sister, Iris. Whatever Michelle would accomplish, Iris would do something but better. In high school, Michelle won District for track, while Iris won State. Michelle even thought this when she became certified as an EMT as she saw Iris going to medical school as the same kind of "greater accomplishment".
• Big Sister Instinct: Michelle was very protective of her sister, Iris, before she vanished 3 years prior to the "Pilot" (1.01). It borders on Knight Templar Big Sister over the course of her search and investigation into her disappearance.
• Brainy Brunette: Is a certified EMT with the brains to match.
• The Captain: Of the EMS 126 crew.
• Friendless Background: Is told by her mother that she used to be a free spirit and fun to be around, but ever since Iris disappeared, Michelle's obsessive drive to find her sister has cost her her social life. Even her relationship with her crew is strictly professional.
• Hero Does Public Service: She volunteers at a homeless shelter when she has time off, and commits herself full-time to it after she reunites with Iris.
• The Medic: Is the captain of the Emergency Medical Services team at the 126.
• Only Friend: To Carlos, though her above-mentioned drive puts some strain on their friendship. This also extends to them being in-laws, since he was married to Iris before she vanished.
• Put on a Bus: Has quit being captain in Season 2 to help mentally ill people on the street, and even abroad as of Season 4, like her sister.
• Stalker without a Crush: Has been harassing and keeping tabs on Dustin, her sister Iris' ex-boyfriend, for years after Iris disappeared. It gets to the point that he takes out a restraining order against her and she’s frequently arrested for disregarding it (with Carlos being her arresting officer each time).

Tim Rosewater

Tim Rosewater

Profession: Paramedic

Played By: Mark Elias

Appearances: 9-1-1: Lone Star

A paramedic who’s part of Michelle Blake's EMS crew.

---

• A Death in the Limelight: The most screentime and character development he gets comes in his final episode.
• Deadpan Snarker: Gets off some good and witty one-liners whenever the EMS team is called on first.
  Incel Protester: Lady co-worker, lady boss? You stink of estrogen, bro.
  Tim: Well, you stink of garlic so I guess we’re even, bro.
• Mauve Shirt: In Season 1, he seemingly had no function other than simply being a member of Michelle's paramedic crew, along with Nancy. Just as he was getting more depth and demonstrating how he desired to try and reassure the people he saved even if he couldn't keep the promises he makes, he's killed after getting struck by a volcanic boulder.
• The One Guy: For EMS 126. Ceases being that after he's killed, with TK taking his place.
• Only Sane Man: In season 1. Whenever Michelle plans to make a risky attempt to save a patient before backup arrives, he’s usually ignored when pointing out the unlawfulness and danger that comes with said attempt.
• Those Two Guys: In Seasons 1 and 2, he’s this with Nancy.
• Underestimating Badassery: Tim expresses severe doubt that Tommy can do her job after eight-or-so years off of the job. As Tommy quickly proves on her first day back, she still very much has the skills. He never doubts her again after that.

Austin Police Department

Carlos Reyes

Carlos Reyes

Profession: Police Officer

Played By: Rafael Silva

Appearances: 9-1-1: Lone Star

A police officer with the Austin Police Department, which works closely with both the Texas Rangers and the Austin Fire Department.

---

• Amicable Exes: With Iris after he reunites with her in season 4.
• Badass in Distress: Gets kidnapped, held prisoner and nearly killed by a serial killer and his elderly mother from the end of “Cry Wolf” (4.03) to “Abandoned” (4.04).
• Closet Gay: Downplayed. Carlos proudly uses his sexuality and his job status in the same sentence after he and TK become boyfriends, and doesn’t think less of himself because of it. But in “Friends with Benefits” (2.04), he reveals that his parents are the two main people he’s had silent Gayngst with, specially after he came out to them as a teenager. Thus, he’s initially reluctant to introduce TK to them as his boyfriend.
  • In “Control Freaks” (4.08), his mother Andrea even admits responsibility for her and his father Gabriel leaving Carlos hanging about what they thought; it turns out that they love him for who he is, but their cultural mindsets had left them stunned silent about his coming-out for several years.
• Fair Cop: Is a very attractive cop. TK frequently lampshades this to flirt with/ tease him.
• Friend on the Force: Is this to Michelle. He seems to be her only friend. This also extends to them being in-laws, as he had a secret marriage to Iris as well.
  • Becomes this for the 126 as well, to the point that all members consider him just as much a part of them as the APD.
• Mr. Fanservice: Muscled, handsome as hell, and gets many scenes to show off it off.
• Not So Above It All:
• Not So Stoic: Carlos keeps a cool head both on and off the job, but occasionally slips when he’s overcome with emotion. It’s especially apparent (but not all negative) as he continues his relationship with TK and becomes closer friends with the 126.
  • When he hears that TK ended up in a coma in “Monster Within” (1.08), he’s tearing up while standing outside his hospital room.
  • As mentioned above, Carlos did not look forward to his parents seeing him with TK, clumsily trying to save face by claiming that he was a “friend”; by the time TK cools down enough to go back to his house, he’s still torn up about it while explaining and apologizing.
  • In “The Big Heat” (2.12), he panics to the point of speechlessness when he finds that the arsonist preset his town house to burn down with him and TK inside. After Owen, Billy and Judd get them out, he nearly lies about being fine before breaking down in TK’s arms.
  • During the ice storm arc in season 3, everyone can tell that something bad happened between Carlos and TK by the way he turns awkwardly defensive when the subject is broached. As TK recovers from hypothermia in the hospital, Carlos then admits to Nancy and Andrea about how heartbroken he is about TK breaking things off with them while similarly not telling him why, and conflicted between being angry, scared, worried and sad when he and the 126 crew learn about his prognosis. When TK wakes up in “Push” (3.04) and lets Carlos lie with him in bed, he’s visibly crying with relief.
  • He’s just as fearful and worried as the rest of the 126 for TK and Owen when he learns about their plane malfunction in “In the Unlikely Event of an Emergency” (3.08); when they reunite, he practically bear hugs TK.
  • While on the phone with Athena in “Prince Albert in a Can” (3.11), he can’t help but cough-laugh at Grace tossing a swatter’s catchphrase back in his face.
  • When TK goes back to attending NA meetings after Sadie drugs him and Carlos, Carlos gives his full support… then gets visibly jealous of TK’s sponsor for a time in “Riddle of the Sphynx” (3.13).
  • Despite his complicated relationship with his father, in “In Sickness and in Health” (4.18) Carlos, while attempting to investigate Gabriel’s murder, ratchets between shame, sorrow and rage for several days; intensely enough to concern TK and Owen. Then he finds a suspect who last called Gabriel and left threatening voicemails, and loses it completely when confronting the man, only backing off when Owen talks him down.
• Official Couple: With TK, specially after they become boyfriends at the end of Season 1. After seasons 3 and 4, they get a Relationship Upgrade to husbands.
• Oops! I Forgot I Was Married: Sort of. At the start of season 4, Carlos admits to TK that his connection to the Blake sisters is more than it was in season 1; in addition to being a voluntary arresting officer for Michelle, he was, at least on paper, married to Iris. It initially worked as a front for his sexuality, and then became a method of paying for her health insurance after she was found until her new job gave her full monetary coverage. This is no longer the case after they have their marriage annulled.
• Real Men Cook: In “Yee-Haw” (1.02), he cooks dinner for T.K. and himself, as a date. The date doesn't end well, but it’s less to do with the meal itself and more with TK panicking about rushing into a relationship.
• Ship Tease: With T.K. They start a romantic relationship at the end of Season 1, and get engaged at the end of Season 3. As of the end of Season 4, they’re Happily Married.
• Two Girls and a Guy: A sibling variant, as he’s the only boy to his two sisters.
• Why Did It Have to Be Snakes?: “Down to Clown” (3.15) implies that Carlos has a general dislike/ fear of reptiles— which is sound, considering that the first lizard TK eagerly adopts as a pet isn’t meant to be a pet. He’s still not over it by “Swipe Left” (4.12), but is willing to compromise with TK when the discussion of having children (or not, in his own case) is brought up, gifting him a bearded dragon.

Profession: Missing Persons Detective

• Friend on the Force: To Carlos, whenever he finds a possible lead on a case he decides to investigate.

Ty O’Brien

Ty O’Brien

Profession: Austin Police Sergeant

Played By: Neal McDonough

9-1-1 Operators

Grace Ryder

Grace Ryder (née Williams)

Profession: 9-1-1 Operator

Played By: Sierra McClain

Appearances: 9-1-1: Lone Star

Grace is a 9-1-1 operator and Judd's wife.

---

• As the Good Book Says...: She’s a devout Christian in her values, and usually quotes from the Bible to calm someone down or attempt to resolve conflicts.
• Beautiful Singing Voice: Kinda par for the course as a devout churchgoer; in “Open” (4.13), her father Benjamin nostalgically recalls her and her two sisters performing together as children, and Judd even mentions her voice being one of the first things about her he fell in love with.
• Beware the Nice Ones: In any given crisis that extends to herself, Grace tends to be the Action Survivor next to Judd. But if she’s focused on helping someone in a particularly hard-hitting case or bringing them to justice, she is focused, even when she has nothing but her wits to protect herself. She’s also not above holding a grudge against anyone who pisses her off— Billy and her father learned that the hard way.
• Deadpan Snarker: She displays a dry wit when dealing with particularly difficult callers.
• Good Stepmother: Very warm and welcoming to her newly discovered stepson Wyatt.
• Happily Married: Is married to Judd in a happy and lovely relationship.
• Huge Guy, Tiny Girl: The height difference between her and her husband speaks for itself.
• Imperiled in Pregnancy: When attempting to drive to the hospital through the ice storm in “Shock and Thaw” (3.03) and “Push” (3.04), she and Billy end up trapped on a gridlocked highway and end up needing to find shelter while she experiences contractions.
• Nice Girl: She's constantly warm and kind to those around her.
• O.O.C. Is Serious Business: Grace may be compassionate and level-headed both on and off the job, but even she has her own limits; at work, it often underscores how much a dire or emotionally touching emergency situation can get to her as much as anyone on the other end of a phone when she expresses her truer emotions (ie. irritation or fear); and outside of it, if even she gives a wrongdoer a piece of her mind, it’s a good sign that they won’t be getting much unsolicited kindness from her.
• Precision F-Strike: Usually not one to overuse profanity, but in “Prince Albert in a Can” (3.10), she uses a jerkass streamer’s boast against him when Athena and her team arrest him in Los Angeles.
  Grace: (while pointing up) It was God’s plan, bitch.

---

• Chuck Cunningham Syndrome: Despite being in a relationship with Owen at the end of Season 1, Zoe is nowhere seen nor mentioned in Season 2, Owen once again being single and allowing him to enter a Friends with Benefits relationship with his ex-wife.
• Hot Teacher: Is a good-looking professor.
• Love Interest: Is set up to be this to Owen in Season 1, but then vanishes in Season 2.

Josie

A woman who Paul meets at a call. They date briefly, until she learns he is trans.

---

• Bested at Bowling: She is able to beat Paul on their bowling date.
• Cat Fight: Is involved in one at a male strip club, Josie was helping her friend and ended up with a face full of stripper glitter.
• One-Shot Character: Only appears in "Studs" (1.05).
• Rescue Romance: After Paul helps Josie after a fight at a strip club in "Studs" (1.05), they strike up a flirty texting relationship and end up going on a date. They only have one date, after Paul reveals that he's trans and Josie admits unfortunately that him being trans is something that she can't get past.

Pearce Risher

Pearce Risher

Profession: Paramedic

Played By: Andy Favreau

Appearances: 9-1-1: Lone Star

A haughty medical worker who applies to Tommy’s 126 paramedic team, then gets hired by the private medical company Paragon.

---

• The Ace: What keeps him on Tommy’s team the longest out of the interviewees in “Everyone and their Brother” (2.06) after Tim’s death, and before TK’s addition.
  • In the series’ Baseball Episode “Red vs. Blue” (3.07), his baseball skills temporarily get him back on the 126 team and turn the tide of a game from the APD’s favor to the firefighters’.
• The Friend Nobody Likes: Despite his impressive qualifications and dedication to saving lives, his avoidance of danger and distaste for the maverick nature of the 126 quickly loses him the members’ collective respect. The few times they have interacted, at least from Tommy’s end, pretty much vibe with barely-concealed contempt.
• Jerkass Has a Point: Downplayed. His aversion to taking chances in the field, especially in “Everyone and their Brother” (2.06), would be completely understandable in the moment for the respect of the APD bomb squad and paramedic fields’ spheres of influence and not risking additional harm in the minefield… had TK not volunteered to join Owen and didn’t have the extra paramedic certification.
  • In “Sellouts” (4.10), it’s implied that Pearce isn’t safe from this at Paragon, either; his numerous complaints about the company’s increasing usage of shoddily-installed/ second-hand equipment and cost-cutting exasperate his boss to the point that he’s disregarded all of them. But, at least one complaint about the former is proven correct when an improperly-installed O2 machine causes an ambulance explosion that nearly kills Pearce, his partner, and a factory worker.
• Laser-Guided Karma: Goes both ways at the end of “Sellouts” (4.10). His own comeuppance isn’t quite as severe as Billy’s, but Pearce’s quick adaptation to Paragon’s exploitative financial policies results in him nearly dying in an ambulance explosion. After Tommy saves his life, he then gets to dish out the karma on his boss by filing a hefty $15-$20 million lawsuit against the company.

Iris Blake

Iris Blake

Profession: Homeless Nursing Assistant

Played By: Lyndsy Fonseca

Appearances: 9-1-1: Lone Star

Michelle's missing younger sister. When Michelle finds her, it's revealed that not only is she homeless, she's suffering from schizophrenia.

---

• Always Someone Better: Michelle describes her as this, having constantly showed her up in all areas of their lives. Unlike most examples, however, Michelle adores her regardless.
• Amicable Exes: After her reappearance in “The New Hotness” (4.01), she becomes this to Carlos. Carlos even trusts her to be his best woman at his and TK’s wedding in “In Sickness and in Health” (4.18).
• Brutal Honesty: A lot of the time, she doesn’t mean to be malicious, and she had shades of this in the past, but the meds she’s taking to treat her schizophrenia certainly… lower her inhibitions, so she often doesn’t hold back anything on her mind. This causes temporary friction between herself, Carlos and TK for a time when she initially refuses to divorce Carlos; when TK presses, she reveals that it’s not because she’s jealous or unsupportive— it’s more because she sees some of her past self in him and decided to annul the marriage rather than go through the legal proceedings of divorce.
• Childhood Friends: Iris was this to Carlos when they were in high school. Eventually, after they got married, Michelle became his sister-in-law, though her disappearance puts strain on both relationships.
• Damsel in Distress: Gets kidnapped and beaten by a serial killer when she goes missing a second time from “The New Hot Mess” (4.02) until midway through “Cry Wolf” (4.03). Even worse, she’s considered an unreliable witness when the police find no evidence that the man was in the house with her.
• Hidden in Plain Sight: In “Austin, We Have a Problem” (1.10), Michelle learns that Iris had been at the homeless encampment she was volunteering at for the last three years.
• Innocently Insensitive: Goes hand-in-hand with her Brutal Honesty; special mention goes to her accidentally triggering TK’s insecurity when she tells him she relates to them both being “hot messes” in their respective relationships with Carlos.
• My Fist Forgives You: Gives Carlos a pretty hard slap for not checking in on her in “The New Hotness” (4.01), but she ultimately doesn’t hold this against him— though she threatens to hit him again for apologizing.
• Sanity Slippage: Iris began to suffer this in the months leading to her disappearance due to having an undiagnosed mental illness (later confirmed as schizophrenia). The call center has records of dozens of calls she made each one made seem more unhinged than the last. By the fourth season, she’s recovering from her time on the street, becoming more emotionally stable, and carrying a full-time job at a homeless shelter.
  • In “Cry Wolf” (4.03), this part of her mental health history comes back to haunt her when one of the detectives investigating her case strongly believes she had a psychotic episode due to lack of evidence from the killer in the house she was found in.
• Walking Spoiler: She's only revealed to be alive in the final episodes of the first season. Even more so in the beginning of the fourth season, when Carlos has to end his own marriage to her and get her consent to do so.

Charles Vega

Charles Vega

Played By: Derek Webster

Appearances: 9-1-1: Lone Star

Tommy's husband, and a former restaurant owner/ gourmet chef.

---

• Foolish Sibling, Responsible Sibling: The Responsible to Julius' foolish.
• Good Parents: Even though he’s bummed at having to shut down his restaurant, he always took joy in spending time with Izzy and Evie when Tommy returns to the field. Doesn’t hurt that he and Tommy are both very doting, gentle, enthusiastic and firm with raising them.
• Househusband: Forced into this as a result of the COVID-19 pandemic shutting his restaurant down.
• Savvy Guy, Energetic Girl: Gender-Inverted; Tommy remembers him as a patient, empathetic optimist, even in her worst moments when they were looking for a home and attempting to have kids.
• Supreme Chef: He owned a restaurant before the pandemic forced him to shut it down, and now makes elaborate meals at home for Tommy and their daughters.
• We Hardly Knew Ye: He dies offscreen from a brain aneurysm toward the end of Season Two.

---

Izzy and Evie Vega

---

Gwyneth Morgan

Gwyneth Morgan

Profession: Law Firm Manager

Played By: Lisa Edelstein

Owen's first wife and TK's mother.

---

• Amicable Exes: With Owen, often combined with Will They or Won't They? to make it very amicable. They are on the verge of getting back together at least twice since their initial divorce in the second season. And even when both times didn't work out, they remained very important to each other right up until her untimely death.
• Good Parents: Despite her rocky marriage to Owen, she did her part just as much as he to care for TK. To the point that both Owen and TK remember her fondly after her death.
• Hello, Attorney!: She’s a high-profile lawyer, easy on the eyes, and as Owen can attest, more than capable of deposing TK’s hospital surgeon after her son gets shot in “Monster Within” (1.08).
• Mama Bear: Very much so to her sons. In TK’s case, during his flashback in “In the Unlikely Event of an Emergency” (3.08); she practically drags him out of a drug den and single-handedly arranged for him to go through drug rehab in Los Angeles, all while he was high and then went through severe withdrawal symptoms. And at the start of the same episode, her last act before she was accidentally killed was to push the stroller carrying Jonah away from a out-of-control biker’s path.
• Masochism Tango: Developed this with Owen in season 2 when she quarantined with him during the COVID-19 pandemic and “Back in the Saddle” (2.01), with a little Snark-to-Snark Combat thrown in. As happy as he was to spend time with her, TK did not appreciate walking in on that dance.
• Spirit Advisor: Since her death in season 3 she has often appeared to Owen in dreams and fantasies to offer him comfort or advice. Even before her death she also appeared this way to her son TK when he was comatose, urging him to wake up.
• Straight Man: Zig-Zagged, as she has had moments where she can be just as vindictive as Owen in her verbal spats with him. It’s also implied both in a flashback during “Awakening” (1.09) and Owen’s contentious relationship with her pet macaw in “The Bird” (3.09) that she took his emotional withdrawal post-9/11 very poorly, which led to their divorce.
• Surprise Pregnancy: With her second ex, Enzo, months before they broke up and she went to Texas. It doesn’t stop her from going through with the term or informing Enzo, and she still has plenty of love for Jonah after his birth.

Andrea Reyes

Andrea Reyes (née Delgado-Estevez)

Played By: Roxana Brusso

Gabriel’s wife and Carlos’ mother.

---

• Happily Married: With Gabriel. This makes her Freak Out when someone shoots and kills him unexpectedly even more painful.
• Not So Above It All: When Owen’s marriage-planning turns nigh-uncontrollable for TK and Carlos in “Control Freaks” (4.08), the two of them turn to her for help in reeling him in— only for her to enthusiastically join in his grand-planning on options for cake selections and floral arrangements.
• Shipper on Deck: Very encouraging and supportive of Carlos and TK’s relationship.
• Women Are Wiser: Often a voice of reason for Carlos. The only exception seems to have been being complicit in not outwardly supporting her son coming out as gay, leading to his Gayngst with her and Gabriel. She admits as much to Owen in “Control Freaks” (4.08).

Gabriel Reyes

Gabriel Reyes

Profession: Texas Ranger Major

Played By: Benito Martinez

Carlos’ father, and a Major in the Texas Rangers.

---

• Batman Gambit: Pulls one off with (initially unwitting) help from Owen and Billy when investigating a series of arsons in season 2; based on a profile of one working among them, he found three people who fit the “traumatized and discontent” description— Owen, Billy, and a disgruntled arson investigator— and sets the three of them up to draw out the real perpetrator after Owen admits to stumbling on one of the fires.
• Da Chief: Of his branch in the Texas Rangers.
• Good Parents: Even when his relationship with Carlos became more complicated (because of The Chains of Commanding and his silence about Carlos’ coming-out), he’s nothing but supportive and protective of his son. His daughters, in addition, remember him fondly being gentle and fun with them and Carlos when they were children.
• Happily Married: With Andrea, from what we see. This makes it even more painful for her and Carlos when he’s suddenly killed.
• Surprisingly Sudden Death: Right after the wedding rehearsal dinner for TK and Carlos in “Best of Men” (4.17), an unknown assailant poses as a delivery man and fatally shoots him in the chest.
• Walking Spoiler: Besides the reasons for his somewhat contentious relationship with Carlos, Gabriel’s investigation of season 2’s arson attacks makes him this. And at the end of season 4, his death devastates his whole family and becomes a catalyst for Carlos’ subsequent Roaring Rampage of Revenge.
• You Are Fat: Andrea lightly ribs him about his need to lose weight and lower his blood pressure on occasion. He takes it in stride, though.

Wyatt Harris

Wyatt Harris

Played By: Jackson Pace

A sensitive young man who visits Judd in season 3, and is revealed to be his illegitimate stepson.

---

• Game-Breaking Injury: While he’s training to become a probationary firefighter, Wyatt gets accidentally hit by a truck in “A House Divided” (4.16); though he survives the collision, he’s left with extensive nerve damage to his arms and legs that necessitate intensive vocational therapy.
• Jock Dad, Nerd Son: Wyatt’s polar opposite activity preferences and interests from him (tabletop gaming, knowledge of alien conspiracy theories, and veganism) throw Judd for a loop when he’s invited to the two’s first bonding activity in “The ATX Files” (3.06).
• Like Father, Unlike Son: This becomes something of a recurring issue for him and Judd as the man tries to get to know Wyatt and become more involved in his life, though Wyatt appreciates his efforts.
• Luke, You Are My Father: This is the main reason he visits Judd in “Child Care” (3.05); he had a genetic test done beforehand, which led him to discover that Judd is his father by blood.
• Shrinking Violet: In “Spring Cleaning” (3.17), his timidity causes him to botch his first impression at a job interview. Later in season 4, Judd also cites this as a major reason as to why he doesn’t believe that Wyatt is cut out to join him as a firefighter.
