You weren't sure whether coming back to the BAU was a blessing or a curse. The last time you were there was.. a little bit of a mess.

Ten months ago, you had a forced transfer from Strauss because your forensic science abilities weren't "needed" in the BAU. But, six months prior you had started a secret relationship with Spencer.

You adored Spencer. You weren't exactly looking for a relationship at the time, and it just happened. Spencer had decided to be impulsive and asked you out, even though he knew it was against the rules.

And ever since then, you two were practically inseparable. You fooled around behind the scenes of cases and kept your mouth shut around your coworkers.

But, when you got called to transfer into a different branch.. you and Spencer had to end things. You were heartbroken. You never realized how much you.. cared for him until you left. You had texted occasionally afterwards, but neither of you mentioned the past.

Now, you're standing in front of the doors of the bullpen, Hotchner and Rossi welcoming you back happily. That's when someone runs head first into your back.

Spencer.

"Oh- Geez, sorry- sorry." Is all he says before he walked over to his desk. You frown slightly, but quickly shake your head to not make your sadness known. How could he just walk right past you like you meant nothing to him?

You kept thinking about that until lunch, you entered the break room and a couple minutes later Spencer had entered. The room was filled with silence before you both spoke—

"Hey, so- uh—" Spencer coughs, and waves his hand to let you go first.
