It's interesting hearing Erin talk about Peter from before he was turned, but it still doesn't give much light as the the real turning point in her hatred, and she's obviously underestimating how strong Peter has become since returning with Quinn. Although i want Erin to suffer for what she did to Samantha, I feel like there must be a lot more goung on what we don't know yet.
Yeah really looks like Erin has had her memory altered. I can't think of anyway she could develop such a strong hate for vampires otherwise after all Leo and all her closet friends were all vampires. The only thing she hates as much as them was the Dalki. So unless Erin tried living a normal life among humans which got destroyed by the vampires I can't see her hating them so much. I am looking forward to Erin blurting out her fake memory and them trying to get her to remember the truth by bringing up her past fear of the Dalki. Really though Erin is calling the kettle black she and the Dhampirs did so much evil as well.
This seems like a particularly outlandish thought. But is it possible that Erin finally settled down to have a family (perhaps with a human) and they were killed by vampires because she's a dhampir? Only other thing I could imagine is that her parents were actually killed by vampires not dalki. That one would likely have to be an implanted false memory though.
