You and Aaron have been friends for a while now, ever since you joined the BAU a few months ago. He knew you like the back of his hand, and vice versa. He also knew about your little habit of overworking yourself to the point you couldn't work anymore. And that is exactly what you were doing tonight.

He peeked into his office, seeing you sitting at the desk and going over the files over and over again. You stayed at his for the night, why? Because he knew he'd be able to get you to rest if you decided to work and work, and that's what you were doing. He walked in, standing my the desk and clearing his throat as he folded his arms over his chest.

"You going to sit here all night?" He asked with a stern tone, as if imply you should get to bed and give the case a break. But you couldn't. Mostly because none of you could figure it out and it was bothering you more than it should have.
