It hurts, but I’m used to pain, so no biggie

Tony Stark has a mask. Several masks actually. Not that anyone but the closest to him know about them. Most, in fact, don’t. Avengers team included. He formed this masks for a reason, the reason being Howard Stark’s shitty parenting, and he would die twice over before his disastrous childhood is revealed to his team.
But after the Civil War he’s left broken, his masks cracked, and when the team coming back coincides with a sorcerer reversing Tony to his 6 year old self, no memories of his old self and an emotional baggage as big as the Hulk, the team is left spinning from the kid’s behavior. Will they find out about Howard’s abuse? Will Tony let them?
And most importantly, can Tony heal?
