I am, I know! WK & Saiyuki fandoms are kind of mysteries to me. I don't know how to navigate them, but I can find the goodfic pretty easily, so there's no motivation to try.

I am much more of a fan of Hakkai/Goku & Hakkai/Sanzo, yeah. But I do at least read this pairing! So it's not like most of fandom's massively overpopular pairings. :D

He probably would, but, yeah, it'd be a much more conscious-decision sort of revenge than the one for Kanan, and I doubt he'd kill anyone who had nothing to do with it, this time.

It is amazing how differently each of them acts around or towards each of the others, really; even Goku, who's supposed to be the least complicated of all of them, has different behaviour sets depending on which one of them he's with.
