Why were Boone and Claire put together for teh UK Dance Promo?

I'm sorry if this has been asked before, but I couldn't remember :S

Does anyone know why Claire and Boone were paired up in the UK Dance Promo? I know that Boone did have a moment where he with Shannon, but why was it that Claire never danced with Charlie?

Were Claire and Boone originally going to have some kind of relationship? или are they connected in a way I just don't see?
