I do agree that it feels dropped, though we don’t really know what Cassian was up to on Niamos before getting taken to the prison. It could have tied into something related to his search for his sister, we just don’t know yet. I’ll wait for the final 2 episodes to make a call on that.
What if I cut the flashback in two? Have the first half from Cassian’s perspective than have the other half later in the episode from Marva’s perspective?
Both scenes could play out as such:
Reinstate the scene of B2EMO showing up to Cassian’s ship when he’s a sleep and he begins to dream about the flashback -> flashback scene plays out up to when Cassian is looking to enter the crashed ship
Reinstate the scene of Marva looking at Cassian’s bedroom and she begins to think about the past when she’s holding Cassian’s spear -> play out the rest of the flashback when Marva enters the crashed ship and takes Cassian
If I did it this way, I could start the show the way it did originally with Cassian on Morlana One. It also breaks up the flashback so it doesn’t overstay it’s welcome.
Breaking it up is probably good if it’s a flashback since it detracts a lot from the main story at this point.
