"Yes, it is," he said with a sigh. "A lot of things have happened since-" He waived his hand toward her. "Since that party of yours. The history books are full of facts, dates and names. It's all rather depressing."
He nodded. "I know it's mental, and I'm not. If we were coming up with a prank, it would have been a lot more fun and a lot less depressing," he said with a grin. "Party of you knows that I'm not lying. You were- wherever you were, ready to go to the party and then all of a sudden, you're at Hogwarts, where you can't Apparate, without using the Floo or a portkey. Nothing explains what happened, because there is no way to explain it."
He walked closer and offered her his arm, because those heels couldn't be comfortable on a stone floor. "Come on, let's walk. I can show you the school as is now. Fourth floor has been turned into research. Seventh floor is the Ministry floor. We didn't have a hospital, but I guess you've just become the Head of Health or whatever they are going to call it."
