Talk:Lydia Martin/@comment-69.47.40.90-20130304192659

Can someone please explain to me why Lydia is immune to both the werewolf bite, and the Kanima's venom? I just started watching this show, and it's starting to seem stupid(confusing) to me already. Please someone give me an explanation. Is Lydia just an ordinary human? Or is she suppose to transform into some kind of supernatural creature?
