Don't read if you are saving last episode to view later.
AnnVan, it was great. The episode opened by explaining how Mitchell met George - Mitchell saved George from being beaten to death by Seth and his vamp buddies when they had spotted him as a werewolf.
Mitchell had not been staked through the heart, and made it to hospital, accompanied by Annie (who refused to go through Death's Door) and George. Great cameo from a hilarious hospital chaplain ('you're kind of sarcastic for a priest, aren't you?', 'well, yes, but then I just, y'know, forgive myself') who helps George protect Mitchell from renewed vamp attack. Meanwhile Annie discovers that she has missed her door and starts hearing voices crying out for help.
Mitchell needs more blood to recover fully and there is a very moving sequence where his 1960's ex volunteers to die to help him recover.
To finish things, Mitchell decides to meet Herrick in a vampire duel, on condition that Herrick will let George and Annie live. He has arranged it for a night when George will transform. Annie wants them all to fight Herrick, George wants to take Nina and run, but agrees to go to the funeral parlour and take a message to Herrick to fix the time and place of the duel.
He returns to the house, where they say goodbye, seemingly for the last time. After George and Mitchell have left, Annie hears the voices again and suddenly sees one of the prisoners from the Vampire's 'blood bank'. He has died, and asks for her help in releasing the others. She discovers that having turned down death has given her useful powers - like throwing vampires across
the room - and she uses those to go the funeral parlour and release the prisoners. But as she is leaving one of the Vamps mutters something about Herrick meeting Mitchell in a dungeon, which she knows is wrong.
Guessing that George has set up a confrontation between himself and Herrick, she finds Mitchell and they run to the isolation room that George uses, to find him locked in with Herrick and beginning to transform. Turns out that the reason vampires hate werewolves is that they 'are the weapon' as George puts it, but although Herrick knows he is going to die he is triumphant, because he believes that killing him will transform George into something less than human.
At that moment, Nina, who has followed Mitchell and Annie, arrives and rushes into the room to help George who is transforming. George pushes her out and the door is closed, as he tells Herrick that what he is doing is done for love, which is very human. Turned into a werewolf, George finishes Herrick and is about to break out of the room, when he sees Nina looking in at him and stops.
The closing moments saw the gang having breakfast the next day, trying to understand if they were really safe. George and Nina quietly talk about what has happened to him, since he was scratched by Tully. Cut to Nina sitting in the bathroom, rolling up her sleeve to look at several scratches George made on her when he pushed her in the isolation room.
The very last scene is of Owen, now in what seems to be a mental institution, talking to a suited man about his story and his need for protection. At first glance the man appears to be some kind of psychiatrist, but on leaving the institution, he makes a phone call, and simply says 'Professor Jared? I think we've found them.'
Cue credits and one highly overexcited Gizmo....as you might be able to tell by the length of this post
