Xander simply laughed at her comment. That wasn't why he put his hands there, but it was a better idea than his wants, so he went with it. Also doing something with his hands helped keep the violent one in check who was itching to shift into a dog form and run around attacking people. He insisted that those Xander viewed as his friends were not so and that alcohol trick was proof of that. The calculating one insisted that was just what kids did and it the kid had no way of knowing Xander had no tolerance.
Glancing at a couple close by dancing, they were far closer than Xander and Roxy, so Xander pulled her closer into him, following her moves as much as he could. "They all dance so close..." He whispered innocently, having her so close still made him nervous, but it made him feel good at the same time. The song mixed into a slow song. The DJ wasn't the best at mixing so the initial change over confused Xander and hurt his delicate ears. He tried to pull back, since Persephone taught him more proper dancing than being up close and personal, but part of him didn't want to move out of her space.
