I don’t think that is why thing turned out how they did. I think Gilroy wanted to use as much of his original 5 season plans but truncated. That inevitably runs into a problem, and thus the whole season feels thematically disjointed. I really wish they had re-written more and just chosen a throughline for the season. They could even do the time jumps, just don’t make each arc clearly feel like a piece of a different season with different ideas going on.
