thinking way too hard about this page from kanan: the last padawan and how much it shows about him as a character during rebels and also how that relates to ezra and their sacrifices at the end of the show
it's clear from the first episode of rebels that kanan has no qualms about attachment in general, which is a stark difference from most of the other jedi that we see. he cares freely and openly and deeply about all the members of the ghost crew. he might care too much at the beginning, but that's part of his journey as a jedi that we see throughout the show.
"you must not grow too attached, too fond, too in love with life as it is now" is a fundamental thing that kanan must remember during season 2 of rebels. because he DID become too attached to his life as it was with the ghost crew running around lothal, and when they join up with the larger rebel fleet, he doesn't like it and dislikes how things are changing. he has to relearn the ability to adapt and change before he's declared a jedi knight in the season 2 finale.
part of being a jedi is loving enough to know when it's time to go, which is something that kanan mastered. he and ezra leave at the end of season 2 to protect the rest of the rebellion, he teaches ezra to let sabine go with her family on mandalore, he helps hera reconcile with her past on ryloth. through love and attachment, kanan also learned sacrifice. he lost everything as he became kanan jarrus instead of caleb dume. he was forced to leave behind all the attachments of his former life in order to survive. he didn't learn to do that necessarily, he was forced into it out of necessity, which is very different than him consciously learning how to let go during rebels.
in rebels, kanan leaves by choice. in season 2, he knows that leaving is necessary to the survival of the rebellion. in season 4, he's standing on top of the fuel tank and holding back the explosion and he probably wants nothing more than to try and go with hera, ezra, and sabine. because that's his FAMILY. he loves them more than anything, but he knows that if he does not let go, they will not survive.
so he does. he sees them one last time, and then he lets them go and sacrifices himself to save them all, and in a way, this was the last lesson he ever taught ezra
its no secret that their sacrifices were meant to mirror each other, but here's the images again for reference
in his final moments, kanan teaches ezra about sacrifice. yes, you must love and feel and experience life, but to be a jedi knight, you must be able to master those feelings and do what you must for the greater good. in his actions, kanan was essentially repeating what depa told him when he was a padawan. "you must not grow too attached, too fond, too in love with life as it is now. those emotions are valuable and must not be surpressed, but you must learn to rule them lest they rule you". ezra fully learns that lesson during "Dume" when he leaves the memory of kanan's death behind in the world between worlds and learns to stop his attachment from going too far.
and also like...kanan's life had FINALLY worked out when he died. hera just said that she loved him, they're back on lothal ready to free their home from the empire, he's figured out this whole jedi thing, and he may or may not know that hera is pregnant with their child depending on your interpretation. but he must let go. he cannot let his love and attachment stop him from doing what must be done for the greater good. he saves them, but he also leads to the empire blowing up their own fuel depot, which is the only reason the rebels can take back lothal. he put his purpose (saving the galaxy) over his feelings (because there was definitely a part of him screaming to go with his family, but he was able to control it in order to see the bigger picture)
the jedi fight for peace and the greater good, which at it's core requires immense selflessness and sacrifice and a clear head acting on logic rather than emotion. kanan and ezra were learning that together throughout the whole show, and one last time, kanan teaches ezra a jedi lesson that he finally figured out through trying to guide ezra through it
"but remember, caleb, the galaxy is far from static, and as it changes, a jedi's role in it too must evolve." jedi were keepers of the peace, then they were generals, then they were scattered teenagers who didn't know what to do in the wake of order 66, and now? now they are rebel fighters, once again getting at the heart of what it is to be a jedi. to be a jedi is to love, to sacrifice, to keep the peace. kanan and ezra show why jedi are KNIGHTS and not diplomats. they fight for peace, but they know it is just that: a bloody, brutal, violent fight, and that those fights require sacrifice in order to keep going. they both embody luthen's line from andor where he says "i burn my life for a sunrise i will never get to see", which is also a perfect way to think about why the jedi fight for peace. they really believe in it, and are willing to lay down their lives to make a peace that will never be achieved in their lifetimes.
(what's also crazy is that in this episode, we're essentially shown that kanan jarrus has found caleb dume again and therefore reconnected with his jedi past but that's a post for a whole other day)
i have so many feelings about this that basically boil down to: rebels is so well written and so underrated and kanan and ezra teach us far more about what the ideal jedi should be than any of the skywalker saga main characters (WHICH IS A VERY HOT TAKE I KNOW but it's my take)
Kanan is just the best 🤎
