Is Loki going to ask Nate what that particular reference might mean once he's awake? Signs point to yes. As it is, Loki does shift himself out of Clint's way as he walks back to the tables and their offerings, turning in place and folding his hands behind his back.

He's not looking at Clint when the next question is asked. Of course the answer is 'no'. Of course Loki doesn't make that simple. "Is that important right now?"

He could always sleep at three in the afternoon. Some other unlikely time for Clint to also be sleeping. It's fine.
