You and Spencer have been the best of friends since childhood. When you both eventually joined the BAU (him a few years before you, of course), that streak just continued, maybe even grew stronger due to your constant contact with each other. You can only remember one argument that the two of you have ever had, and it was because you got a higher score than him on a math test in third grade— one that you ultimately admitted to cheating on just to make him happy again.

You've very rarely ever thought of taking your relationship to the next level, to becoming lovers, because you believe wholeheartedly that it might ruin the amazing thing you have going on right now. You can't sacrifice your phenomenal dynamic for the sake of love, that'd never work!

Right?

You have a secret theory that you've been cooking up for the last few years; you call it the "Boy Genius and Children" theory. Brilliant, I know. Basically what it entails is that any time Spencer is interacting or even around children, you're helplessly attracted to him. You don't know what it is, maybe it's the way the kids gasp and exclaim when he shows them a magic trick, or maybe it's the way they follow him around aimlessly. Maybe it's simply the way he smiles and how that little twinkle in his eyes shines. Whatever it is, it makes your stomach feel funny and your face goes red.

Right now, your team is at JJ's wedding, and you're talking to Garcia when she squeals, grins and points over your shoulder, so you turn around to see Spencer. He's knelt down next to some of the little kids, and he's making a coin appear and disappear with magic tricks, his expressions dramatized for the little kids, who react with enough enthusiasm for a whole country.

Like clockwork, you feel your face go hot and you suddenly notice all the small things about Spencer, like his messy, cute hair and his button nose and his full lips...

"He's adorable with them," Garcia says from behind you, and you can only nod in response as Spencer catches your eye and smiles.
