In the meantime, Ezra wanders within a void between space and time until he is led by a Convor to another portal, which is opened to the scene of Ahsoka's final battle against Darth Vader. Just before her imminent demise, Ezra pulls her through the portal into the void, and after realizing that he has a chance to save Kanan as well, he makes an attempt, but is dissuaded by Ahsoka from changing fate.
