A story at least 7 chapters, which has in it Tony either thinking he is or becoming an age younger than 6 (You can choose). Pairings if you wish, obvious father/son relationship growing between Tony and Gibbs.
Good luck! Message me if you want to do it :D
I'm new to Live Journal, so if this is wrong in anyway please tell me :) I'm usually on fanfic.net but decided to branch out somewhat lol.
