Funny enough, I personally think the previous episode was more impactful for ending this season.

We gain little with having Day pushing himself out of an airlock. Losing the fleet was huge for sure, but taking Hober Mallow's words to heart means that the fleet was already lost since the Spacers and the General had already planned on parting ways with Empire.

Tellem's story didn't need to progress. We lose Salvor, my choice for best character in the season...

Everybody on Terminus lives on in some form. Their loss had an awesome (in the truest sense of the word) effect on the universe. Perhaps they are just data like Seldon is/was, but either way, we lose any impact that planet-wide genocide had.

I'm not sure how runaway Dawn's story will go but I had higher hopes for some sort of plan or action. I suppose this sets up a Spiderman pointing scenario in a future season with betrayed Day and Demerzel's Day confusing everybody and each other. Or instead we have an estranged king seeking his place as Empire, causing a third crisis.

Lastly, Demerzel is obviously capable of talking about her past, her imprisonment, and her programming by Cleon I. Has she attempted to bring this up with the clones in the past? If not, why start now? If so, has she had this conversation before to torture the Cleons before ending them? Has the Prime Radiant allowed her to reason around her directives in some fashion? More questions.
