this is all under the lens of “Kpp'Ar getting fully Out of the Coin” BUT I think a lot about the way Kpp'Ar carries Viren’s narrative weight as well as his own, re: his mistakes. We know Kpp'Ar was in a process of change and reformation before he was coined, which is lampshaded by Terry as the Right Thing To Do re: in contrast to Claudia continually choosing darkness and sacrifice.
However, we also know that Kpp'Ar had some big mistakes he hadn’t fully worked through yet:
- He still had the giant Kruha imprisoned in his basement, and did not immediately set him free post-change of heart, for whatever reason (even if he likely intended to, and didn’t get the chance)
- He engaged in self-eating for unknown reasons
- He was looking for the Garden of Innocents, likely to exploit it for dark magic and/or primal stone ingredients
- Despite likely making attempts, he was unable to successfully destroy the Staff of Ziard, an object that has caused incalculable harm since
- By Viren’s own admission, Kpp'Ar spent years of his life helping Viren become a monster (“helping me become… what I had become” / “and I knew she was right: I had become a monster”)
- Despite having his reasons to not want to use the staff again, I’d wager that “we’ll let this tiny sick child I love like a grandson die” was not 100% the right choice for Kpp'Ar to make
So post-decoining, Kpp'Ar has a lot to… ‘answer’ for, for lack of a better term.
I think the crux of it comes from his choice not to help over Soren. He was willing to let him die, even if Soren’s life has definitely had an ultimately positive impact on the world and people around him. We’ve brushed up against “dark magic as a last resort is Bad Still (but with no alternatives given)” a few times in show, and we’re barreling towards a culmination / fallout with it, and I think Kpp'Ar could easily be instrumental in pushing the story towards that to that fallout through his perspective.
Like if Callum and Claudia are basically Viren split down the middle, and Terry believes that like Kpp'Ar Claudia could change / Soren still, of course, does want his sister back in his life… Eventually helping Callum destroy the Staff of Ziard (the source of Kpp'ar’s 'original sin’) and keep him/Claudia from becoming Monsters while helping Soren bring her home (to un-make his choice to abandon one of Viren’s children to die) would make a lot of sense and go a long way.
