Xavier wasn't entirely sure if this shite with the duck wasn't one of Harry bloody Potter's little tricks to sneak into the Ministry for something. If it wasn't, then it was a bloody good thing that their new entrance guidelines would be put in place within the week. And if it was ... well, they'd get him.
The Minister (well, Yaxley) had kept several people back, checking on each floor, just to be certain. If they happened to come across the duck, well, there were casualties of every war. That idiot Whimple would be devastated if the duck was killed, though. He'd named the thing. It was all terribly ridiculous, and if Xavier hadn't been meeting with Yaxley and the minister when he'd come around, Xavier wouldn't have believed a word of it.
But here he was, coming down to show the peons that yes, everyone was indeed in the Atrium. Well, not the Minister, of course, but department heads. It would be a good time to do a little nosing around - see who was talking with whom.
Umbridge waddled by him, and he gave her a faint, entirely unenthusiastic smile as she headed off. She looked to be on a mission - probably going to corner a Mudblood. Come to think of it, that might be entertaining.
He started to move off in that direction when he spotted a far more amusing target. Stepping up to her, he stood directly in her path. "Auror Tonks," he said before he pretended to frown. "Oh, terribly sorry. You're a married witch now, aren't you? Forgive my lapse, Auror Lupin."
