The professor listened the whole time and thought about what John was saying. Xavier could see John was worried making him think for a moment. When John stopped talking there was a moment of silences though soon broke as Charles left his desk and went round it to get closer to John.

Xavier: “I see, well as you know John the X-Gene can do many things, each having its own effect whether it is good or bad. Also what do you mean by my power is not always my own?”

The man paused for a moment

Xavier: “You should not worry John, change it to be expected, powers evolve and appearances may change but one thing remains the same, you are still you.”

He paused once more before saying something else.

Xavier: “I can take a look for you but there is no way to tell what changes will happen or when they will happen. You just need to relax though I understand your feelings as this is something many mutants your age worry about.”

The professor could not do much himself but he could try and make him understand.

Xavier: “All I can do is help you control these powers, in turn this may help you when the time comes to those changes. John in what way do you want me to help you, do you want me to search your mind or do you want to understand your powers better? The more you know the easy it will be.”

He wanted John to remain calm, he was experiencing something that happens to all mutants and that something was change.
