Papyrus will recombine within a couple nights (after a lot of late hours of talking to himself, sorry in advance to any neighboring sleepytime cells). After that point he's going to have some apologies to give and more people to check up on. And a little more freaking out to do, because RM is dead/an egg and they're all kidnapped without powers, but, but! They've managed to survive all sorts of things! They'll figure something out or get lucky somehow, probably!!!

Anyway, depending on how terrible the things they're instructed to do are, he'll be trying to ingratiate himself for advantages and knowledge to share around. Maybe if he's friendly enough he'll win over some of the technicians! It's worth a try!! And he'll be encouraging people to try doing things that he knows they're skilled or knowledgeable with, so catch him around for that.
