A lot of her edgier statements are actually song lyrics and lines from TV and movies. Lots of teens do that. I freaked out reading some things my DD posted on FB when she was 17, and it turned out they were lines from Sex and The City.

I think Sierra was hiding behind some of this tough talk for two reasons. One, she was defensive because of the gossip and stuff she probably endured. Her dad was busted and went to jail for abusing one of her sisters friends at a sleep over. There is no way she could keep that a secret. And that must have been devastating for her to deal with 'socially.' So she had to act tough and like she didn't care, it didn't bother her, imo.
Chit like that was going to follow her to MH so she had to act like she was tough to be able to deal. Also, she was very pretty and was new to the school. That also makes her a sitting duck and a target. So she had to put up a barrier and a wall to pretend to be tougher than she was, imo. Because in reality, imo. I think she was scared and maybe even kind of depressed.
