Aaron was the unit chief of the BAU, which required alot of time. And a lot of time equals alot of stress. He desperately wanted to try something different, not just interrogate suspects and shoot murderers every day of his life. So he signed up for a triathlon.

He knew he could swim fast and his bike was under repair, so he decided to train for the running first. He got his gear and went for the park, just quietly running laps. He did that everyday that he could, never getting distracted. Never never never.

Until he saw you. On the grass, tying your shoelaces and stretching your joints and muscles. He physically felt himself trip over thin air, but held onto a bench.

Smooth, Aaron. So smooth.
