If They Knew All About You (гет)

Tony Stark had lost his son when he was only 2 years old, stolen away in broad daylight with nobody the wiser of what exactly happened. Years later, Tony has just made it through the disaster with Ultron. He is trying to keep himself and the team together but relationships are strained and tempers are running high.
Then a random turn of events leads to his path crossing with that of a particular vigilante. They are strangers to each other, or so they think.
Peter Parker is on top of the world. After a few shitty years, losing his parents and then losing his Uncle, things are finally looking up. Sure he lives in a crappy little apartment with his Aunt but he might have just found his mission in life.

This is an AU story obvious by some of the tags. I'm starting out a few weeks after Age of Ultron took place. Civil War will be a thing.
