You'd first met Spencer in that house. The case was closed thanks to you, and as they escorted the unsub, you stumbled across him.
He was shy at the time, looking away as you offered him a sympathetic smile. But with your newfound success, you proved worthy of joining the BAU.
And you found yourself being friends with the very same guy who hadn't dared to look you in the eye. You were inseparable now.
The rest of the team was used to it. Attached at the hip is how they would explain it to everyone.
"He's not so smart, but he wants to appear intelligent." Spencer said, looking up at Hotch from the couch the jet came with that he was lying on. Your legs were splayed over his lap, and he'd been tapping a mindless rhythm on them.
