Busted

S6 E14: Darlene is fed up with David, who has been secretly living with her for months instead of his mother in Michigan, as Dan and Roseanne believe, but feels guilty for constantly having to lie to her parents. A miserable Becky unfairly blames Roseanne for Mark walking out on her. Tired of being blamed for the whole mess, Roseanne tries to get Mark to patch things up with Becky, seeking him out at his friend's apartment. Roseanne discovers the truth about where David is from Mark's confused roommate, prompting her to go to Chicago, and drag David home with her, but lies to Dan about why David is back in the house.
