"No it doesn't." Jean said. "Mutation is new, scientifically speaking, we don't know that much about it, and even when you consider the 'trends' we've noticed with the way it behaves, there are always exceptions. Look at me!" She pointed at her blue skin and yellow eyes with a free hand.
"I was born this way, which goes against the trends, and my secondary mutation manifested when I was seven. Who's to say that your secondary mutation can't manifest now. And I'm sure we can figure out a way to test to see if your 'mudar' really exists."
She placed the needle, the vials, the piece of rubber tubing and the sterile swabs on a small tray next to the bed. "Sit down. I'll give Moira a blood sample first, she'll be able to tell me if you've had any changes on a genetic level."
