Finding Family (And Fighting For It)

Peter Parker has had a rough life. His parents died when he was 6 years old, his uncle died in his arms when he was at the age of 14, and then his aunt became negligent and verbally abusive (sorry! I don't hate her, I promise!) after his uncle's death. And that's just what he remembers (he has scars and he doesn't know why, when, where, or even a vague who). Not to mention he's Spiderman. He just wants a family. A home.
Tony Stark lost his son, Peter James Stark, when he was only 2 years old. He was stolen from him at the park. He's been through a lot of betrayals and abandonment. He just wants a family. People he can rely on. Sure, he has Pepper, Rhodey, and Happy. But there's always been something missing since his son was taken. A hole that could never be filled.
What happens when Peter (as Spiderman) finds Tony being kidnapped and mugged?
