yeah, this and everything before has the flow of an awkward teenager that just confidently says whatever pops in their head with no understanding of TPO, especially the jumping to sex questions right after meeting an older girl. She's probably not crazy, just unable to consider how people will take what she says before she speaks and that comes off as scary to someone with secrets. It could be part of some plan but, from what I've seen, this is just how these sorts of teenagers act without thinking.
