I can't remember why there's still a Fitz in space. I must have moved around pieces in my head, because going into the finale I thought frozen Fitz had flown through space to end up in the future timeline, and then he went back to present day with the team through the monolith. But I'm clearly not remembering stuff right.
I didn't feel this episode much either unfortunately. I loved how we got outdoor scenes, and some action, it has been a long time coming. But I wasn't too big on the dramatic speeches, and the effects and fights looked bad compared to earlier seasons. Also such a strange feeling seeing Coulson leave the team. I don't want Shield without him huhu.
When it comes to the seasons I guess I rank them this way:
1. Season 4 (by far)
2. Season 2
3. Season 5 (because of its writing, but it was really not that good a season. Major downgrade from S4)
4. Season 3 (I don't remember it well and will have to rewatch it, but it may or may not be better than S5. Graviton was a real nice villain though.)
5. Season 1
