At Klaus's words, Matt's face paled because he knew what was coming next. He'd known Caroline long enough to know that Klaus had just pushed one button too many for her to contain her anger. And he didn't blame her, really. Except she didn't know the half of it. "Care," he whispered, shaking his head.
His gaze flickered momentarily to Klaus. "We're going now," he said, voice firm as he gripped onto Caroline's arm. "Come on." He tugged her toward the door, not wanting to waste any time. They were being stared at by the other museum-goers. All of whom could easily be innocent victims if Klaus couldn't contain his anger.
