[ Goodness, does she have to explain everything? Rapture just holds back a sigh and feigns indifference instead. ]

Many people didn't think it would be Siren either, but she nearly fooled a bunch of people into thinking that she was horrified at the notion that Dave Strider was perhaps going to come after her. She even blatantly lied to Susan about how her hair powers worked.

Alice is highly trained and, despite her sympathy toward Annie, it doesn't make her any less suspicious. She's militant, thorough, but she still has the skills. It wasn't exactly the cleanest kill that would come from someone like her, but to me, she could still be considered an affable culprit.

Touko, on the other hand... surely, one might thing she isn't so dumb to leave her cigarette ash by the crime scene, right? Well, maybe she was stressed. Maybe it turned out that what she thought was going to turn out, didn't. What do smokers do when they're feeling stressed?

They smoke.
