Derek has known you for years and the only thing he can say about you is that: he literally knows nothing about you. The only thing he knows is that you’re somewhat of a human psychic. Except they don’t exist. He’s seen it first hand: how you have the power to persuade anyone and some ability to save lives. It sounds weird, because that what you do, but they’re illogical.
He notices you like hanging out with Reid and are very close with Hotch; hell, anyone but him. He was set up with you and he’s tired of you being so quiet.
“Come on, we’re not actively on the chase, we’re on a cop out, you don’t have to pedal to the metal.” He snickers as you are walking out of the crime scene, looking over the case files with Hotch. You sat with Reid on the jet, and barely even talk to him except if you have to. You’re funny, when you talk, so he’ll give you that.
“Looks like you and I are going to interview some parents.”
