The less pleasant aspects of this party--the glossing over of any real unpleasantness, the Avoxes serving as furniture--are all lost on Zed. He is enjoying himself without a single thought as to what exactly makes Capitol society tick like this.

Though he does stick his head into the rooms for the other Districts, he ends up spending the bulk of his time in the District 1 room. Why shouldn't he? That's his District, after all, and, most importantly, it is the most luxurious room of them all. Therefore, it shines. While some of the other Tributes might have been gawking at awe in all the finery everywhere, he seems entirely at ease in that sort of environment.

He's still enamored with this thing the Capitolites call body glitter, and he's coated in a silver layer of it that's creating a minor visual assault alongside the equally glittery purple suit and top hat he's wearing. And if he bumps into someone, like he's doing right now, he is quite likely going to leave a large glitter print on them. "Hey, watch it!" Because clearly this impact wasn't his fault, even if he wasn't watching where he was going, instead choosing to focus on a tray of drinks he saw across the room.
