Erin seems the most easily manipulated person in this story. She should be one of immorti's subordinates, she wants to kill vampires because of a few acts by a few people. Imagine all the crimes human have commited against humans. I believe it's pushing it to want to eliminate a race for the crimes of a select few which she does, but she ignores what the humans have done(that and all the vampires come from humans in the first place). So instead she allies with the most scummiest group which leaders survive for 1000 years by absorbing life energy of their suborinates or others to survive. Maybe her parents kept dropping her on her head as a child, then she kept tripping and landing on her head for the last 1000 years. I was expecting her to be a g** slayer or close to it. Maybe she will be once she kills Quinn.
