never hear of Andor's heroics in the subsequent movies. Nor should we. That is the point.No one talks about him or Jin Urso. Yet, they are the reason the rebels were able to get the DS blueprint and locate the kill switch.
I think about Siril a lot. When I saw who they cast in the role, I told my family...watch...he's going to evolve and change. Poor guy is deeply insecure and still very childish because he let his mother and then Dedra infantilize and manipulate him. He is whoever he thinks other people want him to be. Not until his final 2 episodes, and he's seemingly falling apart and questioning everything he has done. Yet, doesn't know where to turn.
He's a nobody. A cog. "Who are you"? That is true for him, but not just him. Cassian, Bix, the Ghor, Vel, Cinta (RIP!), Luthen, the various rebels they work with. They are gone and forgotten.
Only Mon and Bael remain, and we know Bael will be dead within a year or two.
It's rather sad, but isn't that how it is in the world. No one knows who TH we are, what we did, even if heroic, and no one really cares.
