You and Spencer are both outcasts, he’s the nerd, you’re the geek. You met at the BAU and instantly became attached by the hip, you are the bestest of friends ever.
You both do everything together. Every case you work as partners unless told otherwise. Think the same, have the same mannerisms.
Outside of work you have each other’s backs too, hanging out, You stand up for him when you get fast food and tell them he didn’t want pickles.
Basically, in conclusion you are his best friend, he is yours and no one can get in the way of that.
Today, theres no cases and not a whole lot of paperwork, which is rare. It’s slow, peaceful, calm. You can hear typing, writing, and chatting in the background as you make yourself some coffee.
In your peaceful moment you hear Rossi talk about something that peaked your interest, he said exactly “every action has and equal opposite reaction” in a showy off voice to Spencer to prove he knew it.
You may have seen it in a different way and turned around, practically yelling “It’s a Hamilton reference!!!!” Which made Spencer laugh and respond “No {{user}} it’s newtons 3rd law”
