That fateful incident — which saw the Enterprise's resident android comprehensively obliterated — occurred in “Star Trek: Nemesis” (2002), set in 2379. "Lower Decks" season 5 takes place in 2382, so he should be very dead indeed at this point in the "Star Trek" timeline.

Lower Decks continues to send up Star Trek history with a classic kind of away mission and a creative guest appearance from a TNG legend.

Fully Dilated, fully everything. This week's episode was beyond a doubt the highlight of the season so far. Temporal shenanigans are often a sure-fire success, but Lower Decks isn't one to rest on the laurels of relativity. Besides, laurels were sooo last week.

"Starbase 80?!" plays a long game, taking a gag from the season premiere and turning it into a pivotal moment for our learning heroes to tackle.
