What do Ginny and Armpit do after the concert?

After the concert, Ginny and Armpit make their way through a bustling crowd of technicians and assistants to Kaira's dressing room, where they see her arguing with a large black man about whether she should have sung the Janis Joplin song. She then invites them into her dressing room where, over ice cream, she reveals that the man was her stepfather and that she can't stand him. As they chat, Ginny reveals that Armpit was in a correctional facility. Embarrassed, Armpit explains why.
