She should have been in bed. She knew that. Three a.m. was a time for sleeping, not for running around the block, chest heaving and limbs burning from exhaustion. But it was better than pacing around her apartment with a restless energy that made her want to either scream at the top of her lungs or punch the nearest wall.

So she ran. It wasn't long before she lost count of how many times she had gone around, but she kept pushing. She knew that if she stopped, the thoughts would come back. The nagging questions. The utter certainty that she was a fool.

When she did finally stop, it was only because her body simply refused to go any further. Bent over at the waist, she rested her arms on her knees, desperately filling her lungs with air. As the pounding in her ears slowly subsided, she realized that the problem that had chased her out of her apartment was still there. And maybe...maybe there was nothing she could do to make it go away.

She was in love with Aaron Hotchner.

"Dammit," Emily muttered.

And she went back inside.
