Warning! SPOILERS for Obi-Wan Kenobi episode 6.

While Darth Vader speaking with Anakin Skywalker’s voice added to the emotional impact of the Obi-Wan Kenobi finale, it also created some questions. Throughout Obi-Wan Kenobi, the former Jedi Master had been struggling with his past. Reva, the Inquisitor, only made this worse when she revealed Anakin’s true fate and transformation into Darth Vader. With this knowledge, Obi-Wan knew he would eventually have to face both Vader and his own failures.

This led to the final showdown between Obi-Wan and Darth Vader in the Obi-Wan Kenobi finale. Although Obi-Wan initially struggled, nearly getting buried alive, he found motivation by remembering Leia and Luke. With new energy, he was able to face Darth Vader and even slice his mask open.

As Darth Vader spoke, his voice repeatedly switched between his signature mechanical tone and Anakin’s voice, sometimes even mixing the two. Although still heartbroken, this allowed Obi-Wan to find closure by finally talking with Anakin about his fall to the dark side.
