Hearing what Nivalia will do to foxtrot makes Broadshield both uneasy, as well as a little bit angry, considering the past time he was aware that a changeling hypnotized a pony, Canterlot nearly fell. Wanting to avoid that, and to stop her from doing what changelings do, Broadshield chimed in "Nivalia, I don't know. Maybe there's another way we can do this without your changeling magic. Besides, as it's been said, we don't know what will happen if you do it, we may get another moment of Foxtrot attacking us, as well as civilians on the train."
