"You don't have to be able to dance. Just let me lead you. We'll still do better than Peter and his date." Low bar, but hey. Sirius held Remus' hand with an iron grip as he tugged him along, because he had a feeling that his friend would stay reluctant. Whatever, he didn't think it would really hurt their performance. Passion, it was all about passion. As they reached the dance floor, Sirius yelled out to the band. Of course he had talked to them before. "HIT IT!"

And, moments later, they started to play the song he had chosen. And he grabbed Remus properly and marched him across the dance floor with determination.

Sirius had years of having had to learn how to dance backing him up, but at the moment his biggest goal was the run over everyone else on the dance floor, so elegance was a very secondary factor. It was satisfying to see the couples flee from them.
