Prof. Xavier trained superhuman mutants at his School for Gifted Youngsters, whereas Frost was headmistress of the Massachusetts Academy, where she also secretly trained young superhuman mutants, such as the Hellions, in the use of their powers. Hence, Prof. Xavier and Frost would each approach Pryde and her parents as the heads of private schools seeking to recruit her as a talented student. Neither Prof. Xavier nor Frost intended to reveal to Kitty's parents that their daughter was a mutant. Kitty herself was unaware that she was mutant or that she had a superhuman power, until the afternoon that Frost arrived to speak to her parents. While Frost was downstairs, Kitty went to her room upstairs, suffering her worst headache ever. Lying on her bed, Kitty closed her eyes, wishing the headache would stop. It did. Kitty opened her eyes, and, to her surprise, found herself lying on the floor of her living room. Without knowing it, Kitty had used her "phasing" power for the first time and had passed through her bed and the floor into the room below.
