We watched the second half of the Nick Locarno episode of Lower Decks.

Episode 20 of Voyager season 4, Vis a Vis, with the Time Paris body swap.

Discovery we watched Season 4 episodes 1-4. I did not think I had watched any of season 4, but I very clearly remembered all of the Adira/Tilly cadets episode. I remember nothing of the first three episodes though.

And TAS episode 13, the Ambergris experiment. That was one of those episodes we probably should have skipped.
