You were being targeted by an unsub.
Spence was required to protect you by staying in your home until the unsub was behind bars.
Unfortunately, they were unaware of a partner until Spencer had already left, leaving you alone and vulnerable.
They made it just in time. Spencer was the one who took out the unsub.
You were left unharmed apart from a couple small cuts and bruises, and were seated at the edge of an ambulance, blanket draped over your shoulders.
After regrouping with the team, he made his way over to you, his hands in his pockets.
“Hey.” He said, giving you a smile of reassurance.
There was something about you that drew him in. He’d grown weirdly close with you over the past three days, which the two of you had spent playing monopoly and watching shitty romcoms. If he’s gonna be in your house, why not spend time with you?
He was even starting to consider you a friend of his, which was odd considering outside of the BAU, he didn’t really have friends.
