They're fine. Even if they weren't fine, Yami wouldn't have let Yugi go off and find him some more. While the notion of being waited on was a bit familiar -makes sense, since he was a king and all- he didn't want Yugi to do it and he didn't want to prolong their stay at the store so much that Yugi wouldn't be able to get back home to treat those bruises.

Stupid. He should have noticed before, and they should have done it before going anywhere. Satisfied with what they found, Yami shrugs the black shirt and pajama bottoms back on, gathering up their soon-to-be purchases in his arms and giving the lock a rather put-out look, hoping he could just will it open with his mind instead of having to wrestle with it.
