Would there be a problem if it was magic projecting the words? Not that you could tell the difference, but I can talk with Sarah and Tommy and see if they'll have a spell or something that could help.
I need you to read the paperwork and and I need you to give me a verbal agreement at least, if you decide to go ahead with this. This is how I have to work, and I can't and won't change it. Otherwise, I'd be no better than those "terrible muggle scientists" you once told me about.
