Bill had been a regular at a few clubs in Egypt, he liked to dance but more than that he liked to get out of his bubble and away from work. After a week in this place, quiet and lacking a lot of the excitement Bill was used to he needed this even more than usual. Even if flirting and gardening kept him a little busy, he'd been getting antsy. If left alone too long his thoughts drifted to his family, to what could be happening there with a return of The Dark Lord. No he couldn't have that on his mind all the time.
He didn't need much encouragement to fall into step with the other man, Bill's hand on his lower back, perhaps sitting a touch lower than might be polite, at least skirting a boundary.
Klaus was a good dancer and it was far from a chore to do as he asked and move for him, especially since it was essentially just an excuse to get nice and close. The fang in his ear and his own teeth glinted as he smiled and hooked his leg behind the other man's as he dropped him back toward the floor in a dip. "Pretty easy to move when it's with you," Bill said.
