Patty walks in on Meg and Luke (Jamie Elman) while they're making out, and drives a hard bargain. But Meg is more concerned about how "experienced" Luke is. And things might be heating up again between JJ and Colleen (Jessica Collins). Meanwhile, something Jack learns during a confrontation with Nathan (Keith Robinson) at the new North Philly store makes him worry about Helen's voter-registration work. Helen's concerned about it, too, but for a different reason. And Nathan has some advice for Sam (Arlen Escarpata): Quit the track team. Brenda Holloway: Vivian Green.
