Cherub Tony (джен)

In this AU, Tony Stark dies as a child and of course becomes a stubborn little angel, determined to make his Momma smile. Even if he does have to sneak away from Heaven.
(I didn't use major character death tag, because Tony certainly doesn't think he's dead. He doesn't even remember dying.)
EDIT: Somehow Tony talked me into SIX more chapters, where he does more Fixing for people.
