The Orion ship that arrives to collect Tendi is inspired by the one introduced in “The Pirates of Orion”, but appears to be a more modern iteration of that craft, as well as being significantly larger.
There have been a number of references to that episode this season, but STILL no one has said "Oreeeeon" or worn a silly green jumpsuit/helmet combo. Like what are they even doing?
Totally, thank you. Star Trek is goofy as hell sometimes. I think if the Kelpian kid had been a plot device isolated to a single episode, no one would have batted an eye if it were on TNG or VOY. But as the reveal of a season long mystery, it was a big woof for a season and a concept that I was really into.
That said, season 4 really picked up that briefly dropped ball. I think the last two episodes of S4, plus the one with the debate at Federation HQ, will go down as Trek classics once Disco ages a bit.
