Young Jake Potts’ practical joke on his younger brother, Willie, ends in tears when Willie ends up infected with dangerous parasites. That’s it, vacation’s over! We’re turning this ship around. Enterprise has to head to a nearby starbase for emergency medical treatment, or Willie Potts might die; meanwhile, he remains in quarantine in Sickbay, utterly inconsolable. In the midst of comforting Jake, Data abruptly loses interest in the B-plot of the episode and tunes out, running through the next few scenes literally on autopilot.
