Malcolm and Stevie convince their Krelboyne friend Dabney to become more independent from his overprotective mother. Dewey manipulates Reese to do favors for him by pretending Lois is giving Reese orders through the phone. Meanwhile, whilst Piama and Gretchen are on vacation for the weekend, Otto stays with Francis in his bed but to Francis' horror, Otto screams uncontrollably in his sleep.
