In the current Star Wars canon, "Ben" Kenobi's time on Tatooine has never really been explored beyond a few comic books and a brief appearance in Star Wars Rebels. Obi-Wan Kenobi will pick up with the Jedi Master 10 years after he was forced to go into hiding, and it sounds like he hasn't had an easy time of it since the horrifying events of that battle with Anakin Skywalker.
"Obi-Wan is defined by his past to a pretty great degree," writer Joby Harold pondered during a recent interview with EW (via SFFGazette.com). "I mean, Obi-Wan and Anakin [Hayden Christensen] share so much screen time together. They're so close that everything that he's experienced and everything that happened with Anakin cannot help but define him."
"And we meet a man who's very much defined by that history, whether he wants to be or not."
As for how Obi-Wan handles that history when he's forced to come out of hiding to once again face the Dark Side of the Force, Harold added: "Part of the journey of what he goes through is reconciling that past and coming to understand it and coming to understand his place in it."
"And that journey and the places he has to go emotionally as well as physically, and some of those battles he has to fight, are very much to do with facing that past and understanding who he was,," the writer adds, "his part in his own history, in the history of others."
Christensen is expected to suit up as Darth Vader and appear in flashbacks as Anakin, so the Disney+ series is obviously going to flesh out their dynamic in a similar way to The Clone Wars. Whether that means we'll get a live-action take on that armour remains to be seen, but this gives Lucasfilm the opportunity to deepen Obi-Wan and Anakin's connection in a way the prequels didn't.
Obi-Wan Kenobi premieres with its first two episodes on Disney+ on May 27.
