Isn’t that what we just had? I think part of Discovery’s challenge, when it comes to trailers, is trying to sell the notion that Trek tropes that were resolved perfectly satisfactorily in 42 minutes need to be stretched out over a whole season. Would anyone want a whole season of the Crystalline Entity? Or 12 hours of Timescape? Kind of a shame TNG used up Yesterday’s Enterprise, because you could get a whole season out of that, between the anomaly, the altered timeline and meeting the C. But maybe less is more.
