There's nothing wrong with being late if the world isn't in danger. Duster has had enough of that the past few months, and he takes everyone opportunity to catch up on much-needed sleep. To be fair, this morning would have gone by much more quickly if he went to bed at a reasonable hour, but old habits die hard. At least he isn't the night owl he was nearly four years ago.

His head rolls to the side when Aya smacks him, but apart form a irregular snore, he doesn't react to it. If he could sleep while dragged out into the rain, he can ignore a break moment of discomfort.
