I really wish we saw more interactions between master Splinter and Casey in the 2003 series.
I mean the resemblance between the turn of events that made them the way they are is undeniable: They both had their fathers (figure in Splinter's case but still) killed in front of them while being too small and weak to do anything to stop it, both deciding to train and become stronger to make sure something like this ever happens to them again (both scenarios even had Hun front and center).
I mean it's really interesting how despite the almost identical origin stories they turned out so different: master Splinter chooses to really put everything into defense - yeah, he trains his sons to fight but he warns them so much against ever going up to the surface that it's obvious he only means for it to be for self defense, revenge never seems to be something he cares about or wants - even when the opportunity presents itself.
Casey on the other hand goes all out in a "get strong to make them pay" plan, and very recklessly constantly puts himself in harm's way in order to take his trauma out on the purple dragons.
It really is a shame they never really have a conversation about it, especially since the show draws some very clear parallels between them, and I thought master Splinter could really help Casy let go of the past and focus on rebuilding a future the way Splinter did.
Don't get me wrong, angry raph befriending angry human is nice and I appreciate their relationship, I feel like Raphael, who never lost anyone in his life, is a poor choice to preach to Casey about letting go of anger.
I mean your brother making fun of you is not comparable to the trauma Casey lived through...
you can have Raph be the one to relate to the anger issues, but I really think master Splinter should have at some point talked with him as the only one who can really understand some of what he went through, maybe help him find a better way to deal with it, rather than every interaction between them boiling down to " wise master ninja exasperate with/poking fun at dumb clumsy man"...
Idk, just... so much lost potential imo
