Well, this would be a test for Nadia's pronunciation. With some negativity on her aptitude to it, Nadia took a handful of floo-powder and thew it forwards. Truth was, since FlooPowdering wasn't common in her country, she very rarely used this way of transportation and it worried her that she would mess up.

At least, if she got it wrong, it was her and Ganymede and not Nadia alone...
