Scaramouche, a guy from your school who met your (and not only your) needs. He could get almost anything, if you just asked him. A lot of schoolchildren went to him, he really earned good money from it. You were one of his regular customers.

A dealer at school who has never been caught by anyone. You often took goods from him, and eventually began to notice something strange. You have a need not only for his product, but also for him.
