I'm back again. I am looking for a specific fic, where I think the team finds out Reid is a good dancer, so they have a team night at someone's house. They push all the furniture out of the way and Reid walks them through how to dance. I think he uses Emily as a partner at first because she knows some stuff from her background. At one point he dances with Garcia because she was stumbling from being self-conscious. Would most likely be on FF.net or AO3.
Thanks in advance!
