It wasn't that Peter had any worries about his family being bothered by yet another ability that he displayed, or the idea of them backing away from him for it. Those worries were minimal, non-existent in some cases. The real reason was the simple fact that he didn't know what would happen. He never remembered anything from during these painting sessions. The few times it had been used, he remembered the looks and the way it was explained how he had gone... vacant was the most commonly used term. Moving like a puppet, painting something he wouldn't remember seeing. Watching with eyes that seemed blind, but instead saw far too much.
He made sure everyone else was busy before slipping away to Alessa's room, knocking lightly at the door before entering. "Hey," he said. "Sorry it took a bit. It's a little harder for me to vanish than people would expect."
