About the last ask, I don't even bring it up as a negative thing, but as a "very interesting story/concept that could get explored in the fandom, but for some reason doesn't". There are tons of fan stories about Kim feeling bad about kicking Shego in the tower and whatnot, where they explore her "guilt" (I know 99% of the time is used as ship fuel, but still). And I have yet to see a story of Ron that is similar to that I'm just saying there may be a lot of potential there
(I'll get back to the former ask when you clarify what you meant by "in the closet".)
I...don't see Kim feeling guilty about that at all??? She and Ron frequently destroyed villain lairs and just left, left Drakgo in the ocean to drown, let them crash a flaming blimp... They seemed perfectly willing to let their villains and possibly countless henchmen die without a second thought. And consider that evil smile Kim gave after watching Shego fry and the tower collapse...
Yes, I know the obvious answer is cartoon logic of everyone always survives and no one ever gets hurt. That's clearly the lens we are supposed to be viewing the show through. But that's not as fun.
That said, yeah...no, I don't see Kim feeling the least bit guilty or remorseful. And on the cartoon logic vein, we can assume that Warhok and Warmonga survived and not deal with that one either. But we know they died from the creators' statements, and again...not as fun.
But between the two? We see Ron as the more thoughtful individual who cares about his actions, thinks ahead about potential choices, reflects on the past... Fics about Ron dealing with that are out there already. None I've seen quite handle it the way I would, but they exist. And yes, I think that topic has a LOT of potential. 😁
