Okay I had is i my head, I just saw the episode that Kanan died, and Ezra was waching his master's death so did Hera and Sabine.
So let's say that Ezra wanted too save his master when he was in the place where he saved Ahosoka,

could've Ezra didn't listen too Ahosoka and saved Kanan, the past Ezra and Hera and Ezra would died if he did that but saved his master's life. Ezra and Hera and Sabine in the present wouldn't died because of Ezra's Choice, I think if Ezra did do that Ezra's sacrifice wouldn't happen.

Tell me what should've happened in that episode, and remember the force will always be with you. Comment down below
