Dirty Work - S4.E7

When Eiffel picks up signs of a transmission from deep space just hours before Hera's scheduled to go through an internal reset, the crew is divided on whether he should attempt to pursue it or not. But with only the autopilot for backup and an unexpected threat waiting in the wings, they soon discover they're more vulnerable than any of them realize. Plus, above average chimpanzees, horrifying threats of bodily mutilation, Plan C, rules of project management, and elaborate pranks to teach important lessons.
