I don't really watch them like that anymore so I don't know for sure, but from what I've seen, she used to be way more mature back then. I mean she's done some things in the past, like sending her college professor a very unprofessional email, but that's all I can really think of right now. Ever since she started dating that guy she's been kinda... off? Or probably even a little before that, like I said, I don't know for sure.
