Andor creator Tony Gilroy has revealed why he left the mystery of Cassian's sister unresolved in season 2 – and it provides a tragic insight into his character.
If you can remember back to the very first episode of season 1, Cassian is looking for his missing sister Kerri on Morlana One. In subsequent episodes, we learn via flashbacks that the siblings were separated in childhood when Cassian joins a group to go and explore a crashed ship on his home planet Kenari. Once the rest of the group go home, Cassian stays a little longer, and he's found and taken to Ferrix by Maarva, who becomes his adoptive mother.
