The final arc of “Andor” Season 2 has our disparate rebels putting the pieces together about the Empire’s plans to build the Death Star. Luthen (Stellan Skarsgård) gave his life so Kleya (Elizabeth Dulau) could take the information he learned about the space station’s existence to Yavin IV.

This is the last real bit of character building in the series, as most of what happens from here on out is a lot of action — necessary perhaps, but it's not what made this serie

The series finale of Andor brings this chapter of Cassian's story to a close and expertly sets up the events of Rogue One.
