Can we really forget the past? A popular cliché is “forgive and forget,” but is that really possible or something we should strive to do? Throughout the Obi-Wan Kenobi series, he is having an especially hard time moving on from his past. Even though he just wants to accept and forget it, he is constantly reminded of the way Anakin turned to the Dark side. His new friend, Tala Durith, after an explanation of the difficulties she witnessed and experienced, says, “You’re right, Ben. Some things you can’t forget. But you can fight to make them better.”
Throughout the episode, we see multiple flashbacks. Some are with Obi-Wan and Vader, and others are of Reva (The Third Sister) and Vader. Each of these glimpses from the past show us that each character is having trouble forgetting and moving on, even being held back by that, which keeps them from improving their present and future.
