There’s a possibility that Obi-Wan’s younger brother still exists, but don’t expect him to show up as one of the ever-increasing number of Jedi who escaped Order 66 because he isn’t Force sensitive.
Even if Boba Fett’s survival in the Sarlacc Pit and Grand Admiral Thrawn can be resurrected from Legends, who’s to say Owen Kenobi won’t be another abandoned plot point, looking for a new home? Star Wars has a long history of adding to the family tree, and if there’s anything more to Obi-Wan’s brother line, the potential of it being someone we already know is pretty enticing. We’ll keep an eye on that Kenobi bloodline with three episodes left.
