That whine only makes Felix look more self-satisfied, and that gaze warms him up from the inside out. Does he want Sylvain to touch him? Of course. But not yet. Making him wait has its own appeal.

Felix remembers those times when he would turn from felling an opponent in battle to find Sylvain watching him. At the time, focused on the fight and concerned about Sylvain taking his eyes off his own foes, Felix would simply tell him to stop gawking before he got himself killed like the fool he is, and think little more of it. In retrospect, Sylvain's staring might have been a subconscious inspiration for his decision to start performing.

Felix pulls back from that hand, just far enough to deny Sylvain the touch. For now. The rail serves his purposes well; he stretches a leg up onto it and uses it as a sort of horizontal pole to dance with. Still, anytime Sylvain tries to touch him again, he pulls back.

Finally, as the music nears its end, Felix lets himself down on Sylvain's side of the rail to straddle his lap. They don't do lap dances at Medusa, but Felix knows well enough how to use the internet to figure out that they exist. Seated, now, he keeps moving to what remains of the music, giving Sylvain a look that plainly dares him to try touching him again.
