Aboard the Enterprise, an outbreak of some nasty disease called choriocytosis is finally under control. The good doctor assures the crew it’s no longer “even as serious as pneumonia”–which is, um, actually pretty serious? In any case, Kirk tries to drum up excitement for the dedication ceremony they’re en route toward at Deneb V:
