Apollo realized belatedly that his actions might seem slightly odd to the casual observer, but he didn't really care. Now that he had her in his sights he was content to simply watch and wait, knowing that she would eventually have to pass by him. Of course, there was also the fact that he was, quite frankly, one of the most eye-catching people in the room through no fault of his own. You could even say he was radiant.
He found himself bobbing his head to the music, finding it mostly enjoyable although still not certain if he actually liked it or if he was allowing the fervor of the crowd to carry him away. Either was likely.
The fact that all eyes were on Twee was something he found amusing, usually he was the one people were watching that he felt an immense sense of freedom. Oh, he was definitely getting looks from the mostly teenage and early 20's-aged crowd, but nowhere near as many as the little shining star dancing freely in the middle of the room. The almost pure way she interacted with those around her made him feel somewhat odd for watching, but then he saw her glance over her shoulder.
The small smile was quickly returned as Apollo raised his glass to her, clearly intrigued but making no move to join her or meld with the crowd just yet.
