[There's an odd effect of hearing him admit to lying making her feel more free to think it. Willow hates thinking badly of people, and although this whole time she's been trying to convince herself not to trust him because she knows who he is, it hasn't quite worked. He's been humorous and young and human, most of all, which makes it easy to forget that Loki isn't a quaint nickname.
