Harry winced a little. "Yeah. . . something like that," he answered evasively. It wasn't that he didn't think he could trust Ginny. Or Luna, or Neville, or any of the others, for the matter. It was just. . . it was something HE had to do. Bad enough that Hermione and Ron were always in the thick of it. The more people who knew, the more people who'd want to help, and the more chance there was that someone would get hurt. Or that someone would get caught and forced to tell something. It was safer when everyone else was in the dark, was all. For everyone.
He wasn't sure she'd actually listen to that, though. "We can talk about it in the Room," he said finally. Not that he would tell her, really. But he could. . . talk around it better when they were more secure.
They were getting closer to the Room's entrance, and Harry looked around, making sure no one was watching before approaching the corridor. He had the cloak, but he'd put it on when they left, maybe. Unless the room knew how to deliver them an exit in the Gryffindor common room, somehow.
