MakingStarWars.net has published some leaks about Moses Ingram’s character in Obi-Wan Kenobi. This is a very reliable site so all of this is probably true. According to MakingStarWars:
- Ingram is playing Reva, alias the Third Sister
- She’s a brutal and intelligent Inquisitor who hunts Obi-Wan
- On Tatooine, she cuts the hands of people who don’t answer her questions. The Grand Inquisitor is impressed.
- The name Reva is an intentional reference to Revan from the Knights of the Old Republic game. In the Legends continuity, Revan lived thousands of years ago and he has been a Jedi and a Sith.
- Reva has been a Jedi too before turning to the dark side
- Her first scene is an Order 66 flashback.
Besides, LRM claims that Obi-Wan and Darth Vader will have two fights in the series. This is a less reliable site so take this with a grain of salt.
