Alpha Hotch courting Omega Reid by bringing an extra go-bag filled with packed dinners, a thermos of good coffee, and an Omega-brand spare blanket. He purposefully leaves it alongside Reid’s bag so Reid grabs it when they all go to their motel rooms (whether he’s roomed with Reid or not).
Reid, late on their first night of the new case, accidentally opens the extra bag instead of his own, and is confused as to who it must belong to.
He’s so tired, he doesn’t put much more thought into it once he pulls out the blanket and smells Hotch on it, an unconscious purr escaping him as he bundles up with it on the bed, falling asleep in seconds surrounded by the safe scent of comfort and warmth.
In the morning, he’s a little mortified, thinking he must have accidentally taken Hotch’s bag and slept with Hotch’s spare blanket—but then he sees the letter in Hotch’s handwriting:
“I know I’m not the best cook, but I hope this is better than what you find in the vending machine. Sleep well. -Aaron”
Then he registers the food and the coffee, warming it all up in the motel rooms microwave (once he snaps himself out of his daze).
It’s delicious. He’s purring again, wrapped up in the blanket and eating food an Alpha made for him. Not just any Alpha, Hotch. Aaron. Aaron is taking care of him. Providing for him. Courting him.
He notices how Aaron glances at him when they meet up at the station, a small smile on the Alpha’s face when he notes that Spencer looks well rested and fed—and that he’s still carrying the thermos with whatever coffee is left.
They don’t say anything to each other about it yet, they’re at work, but Spencer knows that it’s only a matter of time before Aaron approaches him and asks properly to begin courting.
