Season 2 started out kind of sad with Annie feeling a little lost and lacing in purpose, George and Nina on the outs and Mitchell's inner struggle and secret identity as vampire king causing him stress, but it sure picked up and got exciting! George tries to tranquilize his wolf, but putting the wolf to sleep makes it seep out at random times affecting his personality and causing random outbursts or profanity and violence. That idea didn't work!
Annie met some other ghosts, even a baby! She finally found her inner strength when she was faced with her fear of being tricked to go through the door, but overcame those forces several times over. Mitchell "went dry" and stayed strong convincing the other vampires to join him after Herrick's death by George.
All of those accomplishments went out the window when Nina was tricked by Lucy and Kemp to persuade George to submit to "being cured" at their facility which actually kills werewolves rather than cure them. Lucy seduces and uses Mitchell to get close to George, while Annie wants Kemp, a former priest, to exorcise her from the flat so she can move on through the door.
Learning of Lucy's betrayal and her involvement in blowing up the vampire meeting, Mitchell falls off the wagon big time, then helps George and Nina escape the werewolf killing facility, losing Annie, as Kemp has her sent through the door against her will.
The exciting ending has Lucy and then Kemp track the three supernaturals to their new place in the country, where Kemp totally lost what was left of his mind and kills Lucy (thank goodness, she grated on my nerves) and attempts to kill Nina until she escapes by punching him in the balls and breaking free. Annie saves the day (yes, Annie!) by bursting through the door and dragging Kemp back with her.
Afterward, she speaks to them through an unplugged TV hilariously explaining that she didn't know where she was but she had to fill out forms. The horror!
Vampire Daisy and the vampire Mitchell mercifully saved from execution in an earlier episode, in the final scene, bleed themselves in the snow in a ritual that resurrects Herrick with a howl of energy and victory. It would seem that the new world order is coming after all!
