   Summary

   Tony Stark is five when Bruce moves into Stark Mansion. He’s fourteen when Bruce realizes they have a problem. Nineteen when Bruce sits in the workshop watching him build a metal suit.

   Or, in which Bruce enters Tony’s life much earlier, plays buffer to Howard’s not-so-hot parenting, and realizes that his best friend is a mouthy boy twenty-three years younger than him.
