'Andor' Episode 9 Ending Sets Up a Tragic 'Star Wars' Destiny

As Cassian Andor (Diego Luna) escapes the Ghorman Massacre at the end of Andor Season 2, Episode 8, he brings a little last-minute souvenir with him. After nearly getting killed by an Imperial KX droid, Andor ends up throwing the remains of the droid into his speeder and taking it all the way back to the Rebel base on Yavin 4. And at the end of Episode 9, this same KX droid is rewired to work for the good guys.
