Broken out of the jail you put yourself in

After two idiots tampered with a strange jutsu, Sakumo Hatake is brought back to the land of the living.
It has been a long time since he has been alive, felt the cold air against his skin... felt emotions...
Guilt weighs at his heart as he hides himself from the people of Konoha.
He can't bring himself to face his son after what he did...
Sakumo Hatake ends up using transformation jutsu's to sneak around town spying on his son to see how he has grown.

Sakumo would tell his son eventually... he would.... he had to...

He had to tell him he was alive.
