Of course. Telling him to shut his mouth when he merely asked a simple question. It was typical, really. It was equally irritating, and, Merlin, was she crying? Was she getting ready to? No. She couldn't cry. She could not cry. Marcus, simply, did not handle crying. Hearing girls cry was much like hearing a small child cry. You never knew their reasoning, just that they did it, and got what they wanted after they were done.
"What th'hell do you think I would say, Bell?" He was quite serious when he spoke, his eyes focused and intense on her. He was more confused than annoyed, though there was the slightest hint in his voice when he spoke. What did she not want him to say? That Katie Bell cried in the hallway? That she was spooked over some falling rubble? That she was, obviously, having intense feelings of...something. Guilt? Fear? He could understand those feelings given Bole's activities. But she was with him. He had been in those shoes, before. And, though it was an incredibly odd feeling, Marcus knew he wouldn't let Bole hurt Katie.
Shaking his head, he took a few steps toward her and took a firm hold of her arm. He was careful, though, not to hurt her. He didn't want to upset her even more. He was certain if he did, the tears would start and wouldn't stop. At last while he was there they wouldn't. He would have to get her to, at least, the hallway where the Gryffindor common room was, and then be on his way. Maybe she would compose herself before then.
He kept his hand on her arm, practically ushering her down the hallway once more. The faster he got her safely home, the better. "Just come on, Bell. Before y'go and have yourself a ruddy meltdown in th'middle of th'damn hallway."
