Derek starts to lead Felicity out to the dance floor by the hand when she takes it and he smiles a little, almost apologetically, his eyes flickering away from her and to the band as the song changes and it's something much slower. That's just as well, he thinks, because it's a little less deafening for him when they play the slower tunes. They seem to play a little quieter to go with the mellow speed.

His eyes move back to Felicity and his hand moves toward her waist. "Is it okay if I...?" he asks, his hand hovering a few inches away from her hip as the hand he's holding hers in shifts slightly so that he can settle them into a ballroom dancing position. Derek knows how to do that specifically from the lessons his mother made he and his sister take when they were young, for a wedding once.

The last thing he wants to do is presume anything, but it's the only way he knows how. If she wants to slow dance some other way, she's probably going to have to show him.
