Christy starts having recurring nightmares about relapsing and on Marjorie's advice takes new attendee Jill (Jaime Pressly) under her wing. When Bonnie learns from the landlord that Christy is three months behind on rent, Christy admits she gambled away what little money they had trying to win enough to pay rent. Bonnie and Marjorie come up with enough money for one month's rent to keep the landlord at bay, but Christy, hearing Chef Rudy place a bet on a college football game, can't resist trying to multiply one month's rent into three months' rent: she wins her bet, but gets mugged after cashing in, forcing the family out of the house and into a motel.
