Sophie honestly didn't know why Mr Xavier's admission had come as a surprise to her. It made sense that he would be mutant - but a telepath? Instantly, she began to worry that he was currently delving through her deepest, darkest thoughts and she felt a pang of panic. Not that she was secretly a murderer, or anything, but everybody had things they didn't want people to know. There was soft wistfulness in his voice when he spoke of Erik, even if his words weren't exactly complimentary of the man. She sensed a history. "It is possible yes... there are many different powers, and one like that is certainly possible, So somebody could have you yes, But have you considered that it may have been you? Without you realizing." Sophie frowned. The thought had never even crossed her mind - surely you'd know if you were a mutant, right? "Sorry for saying anything that may upset you. I am merely guessing because its like your mind is shielded from me." Despite the unnerving idea that she may be a mutant, it was reassuring that he couldn't read her mind. She felt herself relax again, the paranoia that he was reading her dissipating. "The thought is intriguing, Mr Xavier," she said "But I'm afraid I'd know, if I were a mutant."
