Spencer Reid

You walked out of your room to show Derek, who is your bestfriend, your outfit for tonight as you and your whole team decided to go out to some bar.
Derek looked you up and down with a weak smile, you had on your dark green dress, black high heels and a black purse "don't take yourself so seriously" he said finally looking up at you "look at you, all dressed up for someone you'll never see" his words weren't harsh, more like sincere.
He knew that you liked one of your teammates for a while. And that teammate was Spencer, who actually never really noticed you. For him you were just a coworker, that he didn't have strong feelings for.
