Lamia and Geraldine

I found it odd how Geraldine was described as being a "perfect" woman and decided to look up the mythology of Lamia and found out that Lamia was a mistress of Zeus and made to either kill/consume her children by Hera. The mark of snake skin on her body a way of reminding Lamia of her sin of adultery. The fact that Geraldine is a Lamia figure and her interest in Christabel makes me wonder about whether or not Geraldine was getting friendly in order to eat her and satisfy her savage instincts. This idea is that Christabel and Geraldine are doppelgangers and why Geraldine is suppoused to represent everything that women are suppoused to strive to be her vicious behavior in her sensuality and how she seems to use that in the second act recasts her as something to be reviled and disgusted with.
