Sal’s parents always liked her brother Walky better, and so over the years she started rebelling more and more to get attention. This culminated in a double convenience store holdup that got her arrested and exiled to a Catholic boarding school in Tennessee for most of her teen years. Her parents expected her to find Jesus (or whatever), but she instead found smoking, tattoos, and motorcycles. As you can imagine, Sal turns a lot of heads, but she finds this mostly annoying. Stop idolizing her, dammit. She can’t help how cool she is.
Sal is roommates with Billie, and she might also have some thing on the side with her calculus T.A., Jason. At night she disappears to hang with her friends, doing Lord knows what.
