Marek knew what she was doing, but that didn't mean it didn't get under his skin. If anything, it was worse that she was deliberately trying to hurt him. He returned her look with a stubborn glare. Really, she should have known that the more she provoked him, the more stubbornly he tended to hang on to whatever side he had taken, or the more likely he was to take a side against what she was saying if he hadn't already chosen one.
In this case, his preferred strategy had already been to stick together, to face down whatever came at the side of the people he cared about. And although he had seen the logic in what she'd been asking of him before, he was ignoring that now.
"Fuck you," he hissed. "You're stuck with me whether you like it or not." He moved to get to his feet, not wanting to hear more of whatever she had to say now, though he wasn't entirely sure she'd let him leave.
