Looking it up, and it really is a shame that there was never a true episode about Rin meeting Koga in Inuyasha. Like he ordered the wolves to kill her village and her, there is absolutely a plot point there that the show/manga could have explored.
I kinda know there is an episode where Rin is saved by Koga (which apparently isn't in the manga but that's fine), but it would have been neat for a whole episode to be dedicated to the two somehow.
Like if Koga would have remembered Rin (doubt it, other than possibly her scent), but mainly Rin somehow being in the care of Koga for whatever reason.
Idk, maybe Jaken, Rin, Koga, and Ayame could have done something. It would have been obvious filler, but there is a whole plot that could have been explored at least a little bit more!
