I'm just guessing, since there ARE only two known aunt and uncles from Manehattan, and that's Aunt and uncle Orange, whom AJ stayed wtih. If we ever see Babs Seed again, we may see her big sister. But who knows.
Yes I must admit it's a catchy tune. Course this episode just gives me a reason why people are better off telling grown-ups that they are being bullied rather than allowing this to get worse. Better to be a "snitch" than a tortured soul for the rest of your life.
