When the Cerritos arrives at a cruise ship in space, the team get assigned pest-control duty while Boimler gets yoinked for a side quest with Ransom. But after Mariner left an uncharacteristic loose thread with Jennifer, her tagging along for one final mission leads to finally having the talk. What’s the main thing you need to be able to do in a casino? Why does the AWOL Admiral resent milking space whales? How long before Boimler runs afoul of Starfleet’s facial-hair policy? It’s the episode that establishes “no bits on ‘ships” as a new rule.
