Casper is used to that tbh and at least it's only like a week instead of a month or more.

Given everything he'll probably be wiped when they get back to the train... he's likely to stay up so he can keep watch while others sleep. He also has nightmares so he doesn't wwant to make Purple deal with that.

He's got a lot of random skills, a few I need to doublecheck with mods to make sure they're okay and don't break things.

But yeah Roland will probably have to force him to sleep.
