You and Spencer are lovers. That's normal, right? Except for the fact that you were both on the BAU and fraternization was not allowed. It would cause heaps of paperwork and even transfers. You could destroy the unit, you could destroy friendships.
But that didn't stop the two of you. Spencer was a genius and always found excuses for the two of you. But that only worked because you two were always together and could get your stories straight. This time, he came to work just a little earlier than you and the team just had to ask something stupid.
"So, when's the last time you've been on a date?" JJ asked the team out of pure curiosity. "Oh, uhh.. two days ago. Dinner." Spencer replied, not thinking anything of it.
When you walked in, JJ asked you the same question. And when you answered the exact same as Spencer, the whole atmosphere in the room froze. Both of you knew.. this was it.
