Cathal had to smirk. He was riling her up without even really trying. Not only was it fun to see how far he could push someone's boundaries before they truly snapped, but his attitude was keeping her at bay. Safer for her in the end, really. After a moment of it, though, it wasn't fun anymore. He didn't really enjoy irritating people or being rude. But he had to do something to keep people from getting to know him, from finding out who he really was and keep them safe from his father. Anyone he cared about was in danger.
Though he wasn't watching her, his peripheral vision caught the frantic movements as she looked around for a way out. "I beg to differ with you, but I think he can keep anyone he wants here. My fa..." He trailed off and then continued again, in another direction. "I think there may be a way out, but I don't think it's right in front of you. You'll be going through that if you want out." He pointed to the Labyrinth and then glanced back down at her. "And good luck with that." She was defenseless, he could see that much. No sword, no aura about her that bespoke magic, nothing. He couldn't really imagine her getting through it alive and that didn't sit well with him. He might be a rude guy, but he wasn't cruel or heartless.
