The team needed you but you weren't answering your phone. They start panicking when they see that you aren't home and ask Garcia to track you down.

Garcia finds out that you're in a Belly Dance class. They go there to try to find you and they find out that you're a teacher of belly dance.

They watch you dance with all the students, in synchrony and having fun. You dance your solo and only at the end of the song that you notice the team standing in the doorway of the room.
