The Whole Team
A bunch of attractive scientists/cops. This is a CSI spin-off after all.
Det. McCanna "Mac" Llewellyn Taylor
- Portrayed by: Gary Sinise
- Atonement Detective / By-the-Book Cop: Former Marine; see Semper Fi below. Tells someone he's about to fire for even considering compromising evidence:There are three things that I'll protect at any cost: the honor of this country, the safety of this city, and the integrity of this lab. As scientists, we have a great deal of power, the ability to assign guilt or innocence. But when we analyze a crime scene, we collect pieces of evidence, we make a promise to the people of this city. A promise to handle that evidence with respect, integrity, and good faith. When you broke this seal, you broke that promise.
- Berserk Button: Do not hurt Christine.
- Clear My Name: "Past Imperfect."
- Cool Shades: Occasionally, such as in "Zoo York," he'll pull Horatio's trick.
- Cowboy Cop: Several times in season 3.
- Crusading Widower: Season 8 opens with him having left the NYPD to work for another lab that's trying to find the DNA of and identify 9/11 victims, including his late wife, Claire.
- Determinator: One Victim of the Week is delivered to a laundry facility that handles linens from hotels all over the city. Flack snarkily comments that there are only about 70,000 hotel rooms in NYC. Our hero's response?
- 10 minutes into the episode, the team has it narrowed down to the correct hotel.
- Embarrassing Middle Name: Mac Llewellyn Taylor. Stan, his first partner, had teased him about it relentlessly back in the day.
- Encyclopaedic Knowledge: Roller Derby rules, weaponry of all types, the ins and outs of dog show competitions, dentistry in other countries, buildings in other cities, space exploration, boxing...Mac's forever spouting some kind of information others don't expect him to know.He and Sheldon are discussing the world of hip hop:Mac: You should hear Aiden talk about this stuff. Close your eyes and she sounds just like Queen Latifa.Sheldon: [surprised] What do you know about Queen Latifa?Mac: [grinning slightly] It's my job to know a little something about everything.
- Exact Words: Mac is told not to utter the word "sniper" during a press conference in "Hide Sight." He doesn't, but verbally agrees with a reporter who does. Chief Carver asks what he's supposed to tell their superiors. Mac replies, "Tell them I never uttered the word 'sniper'."
- A Father to His Men / Benevolent Boss: Tries his best to mentor Danny in Season 1 and comforts him when his brother is severely injured; inspires Lindsay with reenactments in Season 2, hugs her protectively on several occasions, during season 7 reassures her after her ordeal with Shane Casey in "The 34th Floor" and saves her from a hail of bullets in "Life Sentence;" saves Flack's life in the Season 2 finale; gives Sheldon a place to stay when he loses his apartment in "It Happened to Me;" helps Adam deal with issues stemming from his childhood in Season 9.
- Feet-First Introduction: It's actually in CSI: Miami's episode, "MIA/NYC Nonstop," but it's how Mac is initially seen as he exits a police cruiser upon arriving at the scene of the murder of the man Horatio first suspected of the killings in Miami.
- He also gets a feet-first RE-introduction in season 8's "Keep It Real" upon returning to the crime lab after working at Piper Laboratories for a few months during his 10-Minute Retirement.
- Heartbroken Badass / Hurting Hero: Lost his wife, Claire, in the 9/11 attacks. Suffered with insomnia for years afterward.
- It Is Not Your Time: "Near Death."

- Manly Tears:
- Averted with Claire. He doesn't cry when speaking about her to the locked-in victim or at Ground Zero in "Blink" or during his "limbo" period in "Near Death."
- Invoked with Christine. In "Misconceptions," he breaks down when he finally realizes that he's going to lose her if he doesn't swallow his pride, apologize for shutting her out, and open up to her.
- Married to the Job: He doesn't even like to go home to sleep. Christine is helping him get his head out of work now.
- Mysterious Past: The series opens with Mac sitting alone in church at night. The audience isn't told what's bothering him until later in the episode, and details are slowly revealed as the season goes on.

- Official Couple: First with Peyton, then with Christine.
- Only Known By His Nickname: As explained on the Main and Trivia pages, Mac's given name is McCanna.
- Platonic Life-Partners: With Stella. Seems to be it with Jo since Stella left.
- Scars Are Forever: Mac has scars from being burned by a hot piece of shrapnel during the 1983 terrorist bombings in Beirut, from being blown up in "Charge of this Post," and from his bullet wound in "Near Death."
- Semper Fi: Once a Marine, always a Marine. Note his use of the present tense in this exchange from "Tanglewood" in Season 1:Sonny Sassone: That's right. That's the way we do it. Mafia style. You look a man dead in the eye and watch the light go out. But chu wouldn't know anything 'bout *that* would ya, *coppa*?Det. Mac Taylor: I'm a Marine, you little punk. I've put men in the ground on foreign soil so you can sleep at night, but you wouldn't know anything about *that*, would ya - *kid*? Let me tell you something about the mob. Back in their heyday, these old-timers, they dealt in death and violence because of one thing: business. Not sport. They were smart. You punks are idiots.
- Sharp-Dressed Man: He wears a suit to work more often than not (complete with tie in season 1). Even when his suitcase goes missing for weeks upon his return from London in season 4, he still manages to dress nicely. The black button-down shirt he dons before his suitcase is returned is so sharp Danny remarks, "Whoa, Mac, back in black!"
- Single-Episode Handicap: He's stuck at home with his leg propped up, a sprained right arm, and a few broken ribs for most of "Point of View." He's completely healed by "Vacation Getaway."
- The Sleepless: He's an insomniac who doesn't like going home to an empty apartment. Jo once had Flack remove him from a crime scene in an effort to make him go home for a couple hours of sleep. Stella kept on him about it too:Stella: When's the last time you got some sleep?
Mac: What's sleep?
In a later episode:Stella: What do you do when you can't sleep?
Stella: No, what do *normal people* do when they can't sleep?
- Standard Cop Backstory: Military career, deceased spouse, little to no personal life, and an argument can be made that he inadvertently caused the death of a childhood friend's older brother by not shooting the guy who was beating the boy to a pulp when he had the chance (at age 14).
- The Stoic: Sinise himself once said of his character, "He smiles once a season."
- Team Dad: Whenever the others, especially Adam, are goofing around in the lab, he always sets them straight. Usually a stern look will do the trick, but occasionally such as the time Adam & Danny where teasing Lindsay by using age progression software on a pic of her, he'll say something parental like, "Are you three done?" and they'll immediately snap to attention. But let anyone else threaten any of them...
- 10-Minute Retirement: See Crusading Widower above. He was back the next episode.
- Two First Names: Self-explanatory.
Det. Stella Bonasera

- Platonic Life-Partners: With Mac.
- Put on a Bus: At the beginning of season 7. She transfers to New Orleans to head up the crime lab there and is never seen nor heard from again after episode 7.01 (and only because she sent Lindsay a package then). A short time later, tho, Lindsay refers to "the last case Stella was working on" in a conversation with Jo.
- Quirky Curls: Never changes her hairstyle throughout her six seasons. Her mentor, Professor Papadakis, tells her they're what drew his attention to call on her in class all the time.

- Brainy Brunette: It was her analysis of blood spatter in a major case in Montana that caused Mac to hire her in the first place. Inspired by his demonstrations in "Zoo York" and a few other episodes, she becomes a reenactment expert. In one of her earliest episodes, she answers a question of Mac's before he has a chance to ask it. He asks how she knew what he wanted and she explains her thought process, which impresses him. In "The Lady in the Lake," she asks Mac if he believes in luck, then goes into detail as to how she arrived at a conclusion which provided a lead in the case. Mac tells her, "That's brains, not luck."
- Dark and Troubled Past: See Harmful to Minors below. Takes her a while to open up to everyone about it, especially Danny.

- Survivor's Guilt: She's been dealing with this ever since, due to the above. Finally resolved when she successfully testifies against the killer, resulting in him being sent to Death Row and executed.

Dr. Sheldon Hawkes
- Portrayed by: Hill Harper
- Beware the Nice Ones: Sheldon doesn't lose his temper often which makes the moments where he does all the more impactful. A very good example is the episode "Hammer Down," in which Sheldon delivers a vicious tirade to a doctor who was part of a human trafficking network that used the organs of female organs for transplanting among other things. Given that Sheldon was not only a doctor but had also recently lost his savings because of a scam artist, Sheldon's anger at the man for taking advantage of people's trust was very understandable.
- Black and Nerdy
- Clear My Name: "Raising Shane."
- Hero Does Public Service / The Medic: Volunteers at a clinic and as a medic in Central Park on his days off.
- Not That Kind of Doctor: Averted. In "Corporate Warriors," a suspect asks him, "What kind of doctor investigates fires?" Sheldon had spent five years in the ER before transferring to the morgue, then to the Crime Lab.
- Standard Cop Backstory: His sister was murdered and a girlfriend was raped and he failed to be there when she needed him. He doesn't talk about either one of them much at all.

- Secretly Wealthy: Though that may be changing now, since anyone who isn't Jo, and possibly Mac (who may or may not know due to being his beta tester for the pillow, and who mentions Sid's fortune while "in limbo"), has to notice the piano in the morgue.
- Until it conveniently disappears.
- Specs of Awesome: They're what keep him from being blinded, if not killed, by the exploding bullet he extracts from a victim's head.
- Supreme Chef: Mentions recipes he's tried, often with fairly exotic ingredients. Tells Mac in "Food for Thought" that he went to culinary school.

Jo: Mac, you need to get married and have kids, so I don't have to go through all these challenges alone.Mac: Have you lost your mind?Jo: Yeah, don't get married. Just adopt a child. Children are wonderful.Mac: Misery loves company, huh?Jo: You would make a great father.Mac: Jo. Stop.Jo: Don't you ever think about being a grandfather?Mac: [scoffs] Hey, if I buy you a burger and a beer, will you stop talking?
- Episode 7.18, "Identity Crisis," ends with this exchange:
- The Matchmaker:
- Discussed. During Mac's "Near Death" experience in the season 8 finale, he and Sheldon take turns telling each other that they should get married. Each responds with a variation of "You sound like Jo."
- In season 9, Jo tells Mac that he and Christine need to get married and "start popping little blonde babies out into the world." He raises his eyebrows and she says, "I see the way you two look at each other." He gives a slight eyeroll, turns and walks away without a word.
- The Profiler:
Mac: (wide-eyed) Do you happen to know her mother's maiden name?
- Part of her training with the FBI, and she's very good at it. Makes a great first impression on Mac by profiling the victim upon her arrival at the lab in episode 7.01, "The 34th Floor."
