Knox torments Eddie and reveals his dark past, pushing him to betrayal. Willie, arrested over the death of schoolmate Henry Gaines, phones Nucky. Gillian, desperate to regain custody of Tommy but losing her grip, turns to Dunn for a fix. Van Alden's enlisted by Frank and Al Capone to bust some Democrat supporters' heads; Frank's gunned down by deputized Chicago agents. Nucky has Willie stick to a false alibi, pays off the Philadelphia DA to free him, and leaves him with some avuncular advice shortly before Willie's roommate is arrested for Gaines' death. Eddie, back at the Albatross and guilt-ridden about betraying Nucky's trust, jumps out of his window to his death.
