"Pffft" Katya scoffed as she walked back from the toilet (so she'd needed a little break, nature was calling!!!) to find ministry officials from the other departments trying to modify memories, "Amateurs..."

She pasted on a bright smile and bounced over to the group of muggles, her wand firmly in hand under her coat, "Ohmigod!" Zap, she obliviated a muggle, "Did you guys see how that totally hot stunt double jumped off the second floor balcony?!"

And Bam! Another muggle obliviated with the totally easy non-verbal spell.

Okay, so she'd admit that the muggle filming story was a good cover, "And the effects! Woah the effects! I had no idea they did it that way, who woulda thunk it, eh?"

Throwing in some American slang she'd picked up from watching those moving picture boxes felt like a good idea.
