A couple of specifically timed Vader flashes during her dual with Baylan could also further explain why she lost. She was distracted and compromised and he was bringing that even more to the surface.

Without making the film repetitive, what we need here are a few more parallels to “Kenobi.” Both characters need to start clearly broken by Anakin’s fall and regain themselves when they come to accept who he is and who they are today. The biggest difference, besides the framing plot, is that ObiWan faces a fallen Anakin and distances himself in the end, while Ahsoka faces a redeemed and mature Anakin and accepts him as part of herself.
