i think Carter Vaughn would react to being propositioned for a gay threesome by hollanov the same way he'd react to someone asking him to help them move, like "yeah sure no problem. you're buying the pizza and beer haha. what day?" and they're like, "do you actually want to?" and he shrugs and he's like "sure, why not? if i'm free." and they're like, "but like, are you attracted to us?" and he's like "of course man, you're a couple of fucking beauties" and they're like, "but are you gay..? or..bi?" and he's like, "OH! no. no i'm not, sadly. straight as an arrow ahaha but i'll still do the threesome if you want me to! i've done it before. it was a good time!" and hollanov would just blink at him like wtf do we do with that
also, crucially, i believe that if they did actually go through with it, the whole time he'd be like "fuck yeah bro! nice!" and really mean it (and the extreme straight jockbro-y-ness would probably really work for shane)
