Come on Fubuki, he would probably at least fold his futon properly if he was leaving for good. In times like this, when nothing seems right, it's wiser to take a good night sleep, optionally drunk so that dark thoughts don't keep you awake. Everything usually doesn't look as bad in the morning, or at least it would allow to calmly search for a better perspective. This can be learned only through painful experience, though :3
Speaking of "commander's futon", we're about to see a flashback of miso soup incident, followed by tearful heartbreak, aren't we?
