[ Atem tries his best to keep a straight face when he sees Yugi almost fall off the bed and land onto the dog that's been faithfully waiting with them. That's another question that he needs to address at some point, but for the moment, his focus is on Yugi.

He lets out an equally rare chuckle in response to Yugi's exclamation. ]

I would have waited up the rest of the night, if the two of you decided to remain out for a longer period of time.

[ It would have been worth it to him. And besides, it isn't as though he requires sleep. The hours don't really make much difference to him. ]

But yes, sorry, Umbra.

[ He reaches out to pat the dog on the head before once again looking back at his partner. ]

Then I suppose that means that the two of you will have to go out another time so that you can do more of what she wished to do.

[ This time, he can't stop the smile that crosses his face, fully aware that he's teasing Yugi, but genuinely meaning it as well. ]
