Kanan looked down at his hands, then back up at Luke as he said "I guess that is fair." He starred off into space and was quiet for so long that Luke wondered if he was going to answer him after all, when finally Kanan said "That was my old student Ezra and our mutual friend Sabine. A few years ago he had to make a choice, an impossible one really and I couldn't help him in time. I haven't heard from him since he left to follow his new master. Sabine followed him that day, I didn't even know if she was alive until now."
"That's why I am so hesitant to teach you, I don't have the best track record with students." Kanan said that last part as he turned to look Luke in the eyes. Luke didn't respond for a second, but then he said "I guess you and I should get along fine, Kanan. After all my first Master's first student didn't turn out so well either, I mean he did become Darth Vader. It's not your fault, anymore then it was Ben's fault that your student became evil, we all make our own choices, our own destinies."
Kanan sighed and said "Hera told me the same thing pretty much. But I can't help but feel that I failed him somehow." A silence fell between them until Luke's eyes fell on their backpacks. "Shall we see what we can find on these?" he said, lifting up one of the backpacks. Kanan looked at them and said "Sure. Come to my room where we can ensure privacy as we look at them."
After the door to Kanan's room closed behind them, Kanan and Luke started going through them. Some were instructional videos, which Kanan put aside in a pile for Luke and even himself to watch later. Others were more useless then what Kanan had originally thought and every time they finished one of those, he mentally beat himself for picking it instead of another.
Finally as they were nearing the end of the pile they came across something interesting, the trial of Ahsoka Tano. After learning at the end of it that Ahsoka had left, Kanan said "This might be the first one that will be of any use for us, as far as in our search for Jedi." Luke pushed the file button on the bottom that brought up her information.
"Her home world is Shili, she is a Togruta. At the time she left the order she was just 16, which was not to long before the end of it all and… her master was Anakin Skywalker!" he read out loud to Kanan. "Hmm maybe we shouldn't look for her, she could have turned out like her master." Kanan debated out loud. "I think we should give her a chance, after all if all students ended up like their masters there never would have been any dark Jedi." Luke said. "Fair enough, the question is where would she have gone? Back to Shili?"
"Says here that she often visited Padmé of Naboo. Maybe she went there after leaving the order?" Luke said. "It's possible, I remember hearing rumors that Anakin and Padmé were a thing, could be that Ahsoka became friends with her during that time." "Wait Anakin and Padmé were a thing?" Luke asked, to himself he added, "Could this possibly be my mother?" "That's how the stories went, though how much truth there is to them I don't really know. Anyways since we know Ahsoka at least spent time with her, we might as well check Naboo first. It's closer anyways."
Kanan went to tell Hera that once they had dropped off the spy to head to Naboo, leaving Luke with his thoughts. While they were on Naboo what could be the harm in looking up this Padmé? Perhaps he could get Kanan to let him search for Ahsoka on his own and then he could look for her as well. He might finally meet his mother!
*To any hard core fans, I didn't bother to check to see how much closer to the nearest Rebel base from Coruscant is from either Naboo or Shili, so if it turns out that Shili is closer, except my deepest apologize and know that it was an error on my part for not looking it up.*
