I still think they fight like an old married couple tbh. I had an idea and sketched it out (but never finished it) where Leshy leans down beside P03 and they talk as an idle animation like in Act 1 where leshy taps his finger on the table or a spider appears. No idea what they would be talking about. Perhaps talking about last minute changes to a small fight, or just talking shit about Luke and how he's playing. I was thinking that P03 could flash it's smug face or the angry one to show how the talk is going lol. Idk I think it would be a cute n funny thing to happen.
I wasn't even thinking about the idle animations when making this AU but you're absolutely right; they're essential to the experience (and also this is a really fun idea in general).
+ An alternate version
