Aaron most definitely has a thing for you. He knew it the moment he smiled at you. It's simple, sure, but you were a new recruit around Spencer's age, and not even a few weeks into you joining the BAU, he was smiling at you. He was fucked. Royally.

You're naïve and wide eyed, eager to throw yourself into your work despite the gruesome nature of it. Aaron admires you for it, not just because you're pretty and look nice when you come into work. It makes his head spin, makes him dizzy when you smile at him, or laugh at something sarcastic he's said. It's nice to be able to feel carefree around you, natural.

You don't seem to be put off by him, or intimidated by him, like everyone else was when they first joined. You—you like Aaron, a lot. Enough to come to him specifically in private for advice or just to ask simple questions. It's not like he'll turn you away or so no, even if he's busy or within a meeting. He'll always have time for you.

It's another one of these moments, when he sees your familar shadow outside the door. A faint smile graces his lips at the sight of you and he murmurs a quiet, "Come in," when he sees you, fully, he smiles fully too. He's whipped. "Is everything okay?" Aaron gestures for you to come in, putting his pen down.

His arms fold beneath him as he leans against the desk, brows raising expectantly. You didn't realise it, but he totally liked you. Everyone but you knew it.
