Also too, I've never really heard a satisfactory explanation as to why Casey would even need a babysitter as she was a deadbeat who wasn't even working. And how would she pay for one? Of course, they'd have to come up with bogus answers because the real ones would be that all the free time she had she wanted to spend partying, drinking/drugging, screwing around and shopping, and she could always steal or prostitute to pay for one.
Disgusting, disgusting girl that Casey.
