Smarty.

That’s what you’ve called Spencer everyday since the moment you started working at the BAU.

He’s pretty sure he’s never heard you say his name.

And you always say it in that sing song voice.

“Does anyone know…?”

“Smarty does.” You’d grin every time.

At first it would make Spencer blush and stutter, but he was finally getting used to it.

Right now, the team was on a case in New York. You’d find out to dinner and were arriving back at your hotel. Spencer had offered to walk you to your room, since his was down the hall.

“Thank you, Smarty.” You turned on your heel to look at him, a smile on your face as you go to your door.
