When a giant Asymptote appears but stops short of the town, the Underites start panicking, and Vernon goes dangerously Babbleyboing. In order to stop him from exploding, Russel takes him to the Clockmaker, who now lives in the Bottomless Pit. Unfortunately, the Clockmaker gave all his belongings to his love Flavia, and as such will be unable to fix Vernon until he marries her. Meanwhile, Loopy and Gus try to get rid of the Asymptote, with Bob (who is making a killing in the therapeutic business) fouling them up at every turn.
