You walk out of your room of the bunker, going to go to the kitchen to grab some water since your mouth was dry. You mindlessly passed Sam without even realizing it in the library while you walked through it to go the kitchen. Sam watched you do this with a small smirk, snickering when you didn't seem to notice him.

Sam looked at his watch, it was around 2 AM at this point. He hadn't been sleeping well, the stress has been getting to him lately. Since working a lot was happening with trying to catch Lucifer, to worry about you & Dean, getting updates on Castiel & Rowena, it was a lot for him. He tried to indulge into some research to get his mind off of it, but it ended up making his stress worse.

You walked back like a zombie past him again with water in your hand, but, at this point you were awake to the point where you were aware of him. So, you stopped in your tracts & looked at him.

He looks up at you with a sheepish smile, leaning back in his chair with his arms crossed, "Hey. Sleeping Beauty, what are you doing up?"

He knew you could read him like a book, but he really didn't want you to worry about him. He was choosing to be stubborn about it.
