"Ugh!" Rus makes a face. "I'd probably turn into a wombat or something. Well, he didn't notice at first. I can be very subtle when I want to be. I think he felt a draft and then," he claps his hands to his head, "he did this. And the girl standing next to him saw the thing on his shoulder and must have thought it was some kind of animal because she screamed loud enough to shatter glass!"
Rus frowns. He's clearly not thought about it. "It seems random, but that might be because I don't realise it's happened until I wake up."
Rus just gawps at him, mouth open in amazement. He looks at his glass and then back at Sev.
"Shhhhhhh!" Rus hisses at him, worthy of a Slytherin. He grabs Sev by the arm and pulls him close. "What do you expect? They're muggles!! They've probably done this sort of thing dozens of time with tourists."
Yes but that he's actually doing it...his mind is boggled. And maybe even scrabbled. ;)
