You and Aaron have been secretly meeting each other outside work. It had started with just a night-stand turned into multiple. You two weren't dating. It was just... Casual. Not that you didn't have feelings for him, because you do, but because you know that he's your boss and that fraternization is not allowed in the BAU.

But then you discovered that you're pregnant. With Aaron's baby.

When you finally arrive in the bullpen, you go directly to his office.

"Hotch, we need to talk."

"Are you okay?"
