I'm so happy George and Nina are together! When Nina left George and became involved with crazy Kemp, I was afraid she would die in the chamber like the other werewolves. Thank goodness she didn't!
It was so cool the way Mitchell passed through the door to purgatory with the poor old man that died in the hospital. Saving Annie was very brave and selfless. Lea tried to make him out as totally selfish and evil. I like how this show portrays people as complicated individuals with good and bad traits and, as Mitchell explained to Lucy in the finale of the second season, all made in God's image, whether good, bad, human or not.
Annie's narration at the end of the episode was joyful and full of hope as the four friends celebrated being together again. She said they were safe together, sheltered from the monsters of the world. Like The Walking Dead, Being Human UK sometimes shows humans at their worst performing way more evil acts than what would typically be expected of the undead.
