Cain and Abel: With Marcus sort of since they're vampiric "brothers". However in the 4th season with Sally having altered the events of the show Marcus and Aidan are shown to be on excellent terms as they laugh and get drunk on blood together. Marcus even remarks this "So good to see the Aidan I know and love is back".
Death Seeker: During the Season 3 episode I'm so Lonesome I Could Die.
Defiant to the End: Mixed with Heroic Sacrifice. When it becomes clear he isn't getting out of Liam's torture chamber alive, Aidan tries to protect Nora by lying about having killed Brynn, taunting Liam about how she begged for mercy. Josh manages to rescue him in time, but not before Liam gives him a shot of infected blood.
Badass Normal: During the time that he's cured. The self-esteem and perspective he gets following the events of the season 2 finale end up pushing him to become the most heroic member of the cast in season 3.
Humans Are the Real Monsters: While Josh would fervently deny this, almost all the destructive and selfish things that he's done have been a result of his decisions as a human, not his lycanthropy or actions as a wolf.
Only Sane Man: Of all the characters in the show, Josh is easily the one that tries hardest to be human.
Our Werewolves Are Different: After being turned a second time and passing through Donna's door, Josh became what can best be described as a reverse werewolf, being stuck in wolf form throughout most of the month and only becoming human again on the full moon. Sally uses blood magic to reverse this, but the spell was not completed correctly, and though Josh is now mostly human, he is still very much affected by his wolf throughout the month, having extreme mood swings and turning when he least expects it. As far as we know, he is the only werewolf in existence that can turn without a full moon, unless those he was forced into turning share his ability.
Papa Wolf: Josh has become one for his adopted family. Ironically, he's more of a wolf as a man protecting his family than he ever was as an actual werewolf. Even Liam is impressed.
Status Quo Is God: Spends most of the third season as a human once he kills Ray. Comes to an end when he attempts to save Aidan and winds up getting injured by Liam.
Shapeshifter Mode Lock: For three months after the events of the Season 3 finale. It gets bad enough that he starts to forget what it's like to be human.
Took a Level in Badass: After he kills Ray. The submissive, non-confrontational Josh of the first two seasons is gone in season three, replaced by a Josh that is confident and not afraid to face danger head-on (or even to take a life) to protect his family.
He becomes incredibly powerful after his curse worsens, to the point where he can single-handedly fight off multiple vampires without the influence of the full moon.
An impulsive young ghost who is trying to find her place in the world now that she's dead.
Ambiguously Bi: Sally tends to come off as this on occasion. For instance while talking at Emily, Josh's sister, she says she could make her feel happy. And when Nora comes over, Sally promptly quips that she's hot and has nice boobs.
Ambiguously Brown: "Get Out of My Dreams, Get Into My Mouth" revealed she is at least part Indian (as in South Asian, not Native American).
Axe Crazy: after it's revealed that the Reaper is actually her.
Butterfly of Doom: After Sally uses magic and is sent back in time to the night she died, she decides to save herself from her own death at the hands of Danny. As she still possesses knowledge of her life with Aidan, Josh, and Nora, she tries her best to rewrite history with herself still part of their lives but saving them from all of the problems that befell them. This backfires entirely on her: Bridget dies when she dates Danny leaving her to suspect Danny killed her. She becomes a werewolf instead of Nora, keeping Josh and Nora from ever becoming close. And when she and Aidan fall in love, it only drives Josh away from them and with Ray, ultimately resulting in her death, again.
Refusal of the Call: In Season 3, Sally no longer wants anything to do with trying to help ghosts and other people as it has always ended badly for everybody. She goes so far as to disperse ghosts who try to ask her for help. She turns around by Season 4.
Sanity Slippage: Season 2 reveals that she began going insane after missing her door, and only snapped back to reality after shredding herself.
Set Right What Once Went Wrong: After being sent back in time to the night of her death, she manages to merge with her past self and now Trapped in the Past decides to use her knowledge of her life with Josh and Aidan to make their lives in this timeline better, but only makes things worse.
Our Werewolves Are Different: It would seem that wolves turned from humans with a lot of emotional baggage (an abusive boyfriend, in Nora's case) are even more violent, since their built-up anger is not inhibited in wolf form. Nora also reveals that she can remember everything from her transformations, which is probably due to her being more accepting of the transformation than Josh.
Humans living in Boston who interact with the cast. They don't generally stay human very long. Supporting characters that spend a significant amount of screen time as humans but are turned into monsters later in the series will also be listed under this section.
Portrayed By: Jason Spevack
A young boy from the neighborhood Aidan befriends. Killed when he walked into the street and was hit by a car. Rebecca turns him thinking it would make Aidan happy, but Aidan later kills him because he's made to believe Bernie can't control himself.
Jerkass: Wasn't very nice to Sally when she was alive, killed her, and when she tries to haunt him he taunts her about it
Took a Level in Badass: He picked up on a lot of ghost tricks more quickly than Sally did after he died. He says this was due to him dying in prison. It doesn't help him.
The Sociopath: How in the hell did he get married to Sally in the first place?
Portrayed By: Alison Louder
Josh's younger sister with a rebellious streak a mile wide.
The Alcoholic: Between seasons 3 and 4 Emily has to go into rehab. When she gets out she tries to crash with Josh and Nora but their chaotic life (with a magical assist from Sally) almost leads her to an Off The Wagon moment. She leaves because her fragile sobriety can't handle it.
A teenage boy born with a severely weakened immune system that lives in a glass enclosure in the hospital to protect him from disease. Since he has had almost no contact with germs throughout his entire life, Aidan starts using him as a supply of clean blood.
Bubble Boy: Portrayed completely seriously. He eventually comments that what he has is not a life, and he will walk out of the room when he turns 18, resulting in his death unless Aidan turns him.
He also hates it when people call him a Bubble Boy.
Came Back Wrong: Because he was vamped with cursed werewolf blood, Kenny came back as an extra hungry, extra disgusting vampire.
Genre Savvy: There isn't much to do in his enclosure other than watch movies, so he recognizes Aidan as a vampire almost immediately.
Glamour: When we first see Kenny in Season 4, he looks completely normal. However, a later episode reveals that Kenny is still a deformed vampire, and he is using his mind control powers to appear normal. Since he is contaminated by werewolf blood, he has the power to compel other vampires.
Revenge: First tries to kill Aidan for the death of his werewolf girlfriend, then compels him into trying to kill Josh.
Vampire Wannabe: Though you could hardly blame him, given his initial condition.
Portrayed By: Jesse Rath
Sally's younger brother who returns to Boston in an attempt to scam Aidan and Josh out of the rent money they owe his and Sally's father, as he inherited the apartment after Danny and Sally's deaths. When he sees Sally after she is reanimated, she rushes to find a way to save his life, otherwise he will die due to the magic. He returns in season 4 to evict the group from the house.
Back for the Dead: Is killed by an unknown entity in the house in "Cheater of the Pack."
From Nobody to Nightmare: As a human, Henry was rather timid and tame, if expressing curiosity and desire to experience being a soldier and killing. As a vampire, he's cocky, bold, and perfectly willing to act on his ambitions and killer instincts.
Come season 3... he's glamoured a human girl into being complacent with being imprisoned so that he has a supply of untainted blood to survive on.
Mind-Control Eyes: Standard for vampires, but Aidan often had Henry do it for him because Aidan himself is terrible at it.
Normally, I Would Be Dead Now: Henry is harder to kill than a cockroach. He served in World War One, was a fugitive from the vampire world for eighty years, got skinned, extricated himself from a meat hook, and when the plague came around, he still wouldn't die. The plague eventually does him in, though.
Cain and Abel: With Aidan. However in the 4th season with Sally having altered the events of the show Marcus and Aidan are shown to be on excellent terms as they laugh and get drunk on blood together. Marcus even remarks this "So good to see the Aidan I know and love is back".
We Used to Be Friends: [[spoiler: In season 4 its shown that Marcus and Aidan may have actually been friends and got along. Aidan's choice to leave The Family and stop drinking live seemed to have been the cause of the rift in their relationship; hence the animosity in season 1.
You Never Did That for Me: After Bishop gets mad at Marcus for attacking Emily; Marcus remarks that if it had been Aidan, Bishop would have essentially patted him on the back.
Portrayed By: Deena Aziz
The most powerful and ancient vampire of them all, who returns to Boston in Season 2.
Purebred werewolf twins that offer to fund Josh's research.
Affably Evil: Brynn. According to Nora when running off with her off-screen, she is much more sadistic.
And I Must Scream: They describe their human existence like this. Josh is uncomfortable with heightened senses and moods the few days before a full moon, they feel that way every moment they're not wolves.
Bullying A Vampire: Taunting Aidan was probably not the best move, Connor. Especially since he had a rifle loaded with silver bullets.
Killed Off for Real: Both of them. Connor was first killed by Aidan and later Nora killed Brynn during the time she ran away with her.
Morality Chain: Nora suggests that Connor was this to Brynn, not the other way around. Of course, this is a relative chain since Connor's idea of a good time is torturing vampires and hunting them down for fun. One can only imagine what Nora might have seen Brynn do without Connor's influence.
It's suggested that it's torturing and eating humans.
Our Werewolves Are Different: They're pure-bred werewolves whose senses are constantly heightened, not just a day or two before the full moon.
Brynn and Connor's father, who comes to Boston in the third season to try and find out what happened to to his son and daughter.
Anti-Villain: If you think about it, extermination of all vampires WOULD probably make the world a better place, and much of his motivation comes from love for his children, but he's also a major antagonist.
On the other hand, he also has very little regard for humans, so in that sense, he's not really any better than the vampires he claims to be superior to despite his other claim of being part of 'nature's will'. Plus, despite being concerned with the safety of werewolves, he doesn't really have any reverence for other werewolves either, generally using them as pawns or tools.
Badass: He was introduced into the show by killing an entire room full of (admittedly sick) vampires.
Evil Counterpart: Well... eviler anyway to Bishop. Both are very similar in a lot of ways but Bishop at least made the attempt at being civil and civilized. Liam clearly partakes in human culture because of necessity or because it's useful.
Fate Worse than Death: Combined with Our Ghosts Are Different, because he died in a drowning accident he relives the moment of his death, being strangled underwater and drowning all over, again, culminating in an explosion of ghostly water.
He later ends up being "reaped" by Sally while she's under the influence of Scott, and is sent to Limbo where he is forced to keep drowning except for the times Sally manages to pull him out to try to escape.
And then, after he escapes that, he becomes a ravenous flesh-eating zombie who eats cats to keep from rotting, and very nearly eats his girlfriend Zoe as well. Being bashed in the head and becoming a ghost again is actually a relief for him
Didn't think we were done yet, did you? After passing through his door, his soul is destroyed and consumed by Donna. Poor guy can't catch a break.
A friend of Sally's who committed suicide while they were still in high school over bullying. They reunite when Sally decides to go to her high school reunion as a ghost, mostly to confront the popular girl who died recently. Stevie introduces Sally to several other teenaged boy ghost friends of his, and indirectly teachers her about possessing and shredding.
Fate Worse than Death: After being shredded by Sally, Stevie's punishment in limbo is to watch his family live on happily without him as he hung from a tree outside, despite the fact he overdosed.
I'm a Humanitarian: Despite Sally's warnings never to see his family again, Stevie gives into temptation and visits his mother and father who are happy to see him, but are cursed to die because of the spell. As his flesh craving hunger hits him during the decomposition, he decides to eat his parents' corpses. He admits this to Sally and Josh, and later admits that he also killed and ate the mailman.
Portrayed By: Dusan Ducic
A powerful ghost that appears to Sally in a dream. He's actually a part of Sally's subconsciousness.
A strange woman that works at a local soup kitchen. She also happens to be a practitioner of the occult arts, and offers to bring Sally back for Josh and Nora... for a price. After her death at the hand of Sally, she becomes intrinsically linked to Sally's spirit, particularly their magical abilities. She later asks Sally to close up her only portal into the living plane, her death spot.
Affably Evil: Is actually pretty friendly to Sally in the season 4 premiere. Of course, she admits that she's just biding her time as pleasantly as possible until Sally inevitably gives her what she wants.
Proves to be just as affable when helping Sally later in the season.
Back from the Dead: Donna reveals to Sally that she died once already, and her becoming a witch was a result of this.
Big Bad: One of season three's two Big Bads, and arguably the most powerful adversary the protagonists have faced thus far.
Your Soul Is Mine: Devours souls in order to sustain her youth. Even says the trope name, word for word, when making a deal with Sally.
A demonic spirit that has inhabited the roommate's Boston brownstone for forty years. Her power has only grown with every death to take place inside the house, and she's not about to let the protagonists leave without a fight.
