Although Scott does not make the familial connection between Daniel and himself, he suspects that his presence in this time (along with Jean's) did something else to affect the course of history, aside from stopping Mister Sinister and Apocalypse. When Scott is sixteen, he runs away from the orphanage, and while wandering the streets is taken in by Charles Xavier. On a trip to New York with his orphanage supervisor Scott walks across a construction site and his optic beam activates.
