In this one shot peter (without wanda) is young and has joined the x men he discovered his powers younger then canon.

Peters P.O.V

I was running and running and guess what RUNNING!!!! Now that I'm 8 mommy said I could see the man that visited us he said that I was safer with him.
Mommy said that if I stress him out more than I do her his hair would fall out . Imagine that. Haha. He would look so funny .

Mommy said that she was going to drive me but I said 'no' because I'm big enough to go on my own. So I got directions but I took the long way . But the penguins in here are really cool. Am I in a zoo . It's really big so big I can't even see any walls or other exhibits but it's cool.
Oh look a jet.

Xmen / general P.O.V

Cyclops saw the boy first he had managed to get here within in 2 hours and was now confusing penguins. They landed the x jet next to the small silver haired giggling boy. Jean walked up to him and smiled
"How did you get here kid we are in Antarctica ?"

The question was met by an awquard smile "thats a weird name for a zoo. But sorry mister I may have turned the wrong way. Ooh what's that?" He ran off saying.

Why Jean and Scott had been Peters chafferones no one knows but they did all go sight seeing around the world because of one really distracted silver haired boy
