In the first episode of the third season, vampire Mitchell rescues his friend Annie (Lenora Chrichlow) from the other side only to be confronted by the ghost of one of the women he had slain on a train massacre in Season Two. She explains to him that he can take Annie back but there's a price. He's fated to meet his end by the hands of a werwolf. In the next episode werewolves George and Nina encounter Adam, who looks like a kid but is a 46 year old vampire. His father dies in the hospital, of old age, and it's a problem since that's where he's been getting his food. They try to find him a home and it looks like a vampire couple will take him in, for their own interests, not his. In the third episode a zombie, who doesn't realize she's a zombie, follows Annie back to their house and is a big annoyance. It's not until episode four, "The Pack", that we're introduced to the season's most interesting characters--a werewolf father, McNair (Robeson Green of WIRE IN THE BLOOD) and his son. Mitchell has the suspicion that these werewolves may be the ones fated to kill him, as they are very blatant in their slaying of vampires. We learn that vampires capture werewolves and use them for sport, betting on them as they rip each other to bits in cages. In fact, this is how McNair became such a monster--and it was Herrick, the old vamp who originally transformed Mitchell into a bloodsucker--who is responsible.
Evil vampire Herrick actually returns from the dead. He was was ripped to pieces by George in the first season and it's a mystery as to how he's "alive". Now he has no memory of his former self and is sort of like a brain damaged uncle they keep in the attic. Nina and George help him much to Mitchells' dismay. In one of the last episodes George finds out that his father has died and goes to the funeral where he encounters the man's ghost and catches up with him, as he's been presumed dead for two years. His wife left him and he'd been living as a sad sack in a trailer. George sets things straight as much as he can.
The last two episodes, culminating in "The Wolf Shaped Bullet", end Mitchell's story line. The police, with a tip from one of Mithcell's friends, discover that he's the one who killed all those people on the subway. They burst into the house and capture him and take him to the police station. However, proof that a vampire exists will change everything for all supernatural creatures--so someone unexpectedly steps in and rescues him from the cell. But they can't rescue him from his ultimate fate.
This is my least favorite season. The romance between the vampire Mitchell and the ghost Annie doesn't really work, Mitchell's whining about being a hungry vampire gets quickly annoying, and there's very little on the special effects side, especially with the werewolves. It also seems as if everything was rushed to get to that ending, which ties up a few story lines but leaves it wide open for another season. I am just not that excited for another season...
