"Ermm. . ." Harry had spent years evading teachers, not telling the whole truth, and keeping his secrets between himself and Hermione and Ron, only. He wasn't a half bad liar when he really tried. Put on the spot by Ginny though, he might as well have been horrible at it. "I uh, asked her what she thought about the room bit," he answered. Which was true. Sort of. "She didn't really have much to say." Also true. If not quite how she'd meant it, or what Harry had asked. It was close enough.
"I've got the cloak, but we probably won't need it until later anyway," Harry offered, starting off toward the stairs that led toward the hall the room entrance was on. "Are you going in to Hogsmeade this weekend?" he asked, reaching for the first topic that came to mind. And then kicking himself inwardly, since she'd ask if he was, and he was. . . doing something else he couldn't talk about.
