Twins, Orphaned at Ten
Clint Barton was a lucky man. Besides being an Avenger, he had a wife, a son, a daughter, and another kid on the way. He also had the best friends he could ask for. One of them, Tony Stark, used to make weapons, and although he had a change-of-heart and switched his hobby to suits of armor, his weapons still existed and were in the hands of a vengeful company called Hydra. For whatever reason, Hydra wanted to get revenge on the city of Sokovia and they bombed them. The survivors believed Stark was to blame, though there were more casualties than there were survivors.
Now, it's the Avengers' job to help by rebuilding the city and looking for any signs of life. Clint came across something life changing....
