#Bill might care but he's too emotionally constipated to do anything vaguely helpful without three different levels of deniability

was bill mad at the cultists BEFORE he knew about the whole “we cut out your husband’s tongue for being ‘blasphemous’” thing? id imagine he’s the type to be mad at anyone (but him, if current dipper is into that) messing up his stuff. and was there a point where he clocked just how traumatized cult!dipper was?

Bill's initial impression was that they were a bunch of goddamn jackasses, but he wasn't mad at them yet! Sure, they scratched up his husband pretty deeply, and that's more than worthy of some retaliation. But it did summon him right to the guy! Punishment could be put off; he was pretty high on getting to see his human again! And, hey, what's the point in obliterating a perfectly good cult? Someone would pay eventually, but there wasn't a good reason to exterminate 'em. Once he brought Dipper home, and noticed how he behaved, though - That's when he started getting really irritated.

Too scrawny, for one. Too scared, for another. Bill's no stranger to inflicting horrible mental damage and the signs were all there! It'd be one thing to have a worshipful, devout husband bowing and scraping and flattering his ego. It was another entirely to see him shiver in terror while avoiding Bill as much as possible. Displaying no curiosity, no stubborn tendencies. No real kick to the guy, while also failing to eat well or drink well or thrive, even outside of that environment. And always, infuriatingly, remaining completely silent.

Something went down back at that ramshackle patched-together pile of crap they called a cult, and it was not to Bill's liking. And once the tongue thing came to light? That was the last fucking straw.
