Clint, after the death of Laura and his unborn son, moves to S.H.I.E.L.D. headquarters. He's soon in the company of Tony Stark, Bruce Banner, Natasha Romanov, Steve Rogers, and Wanda Maximoff. Clint's proven wrong in thinking that his life might find normalcy after the battle with Ultron as Tony and Bruce succeed in something nobody anticipated or believed possible - bringing Pietro back to life.
Slight Brutasha, and Clintasha if you squint your eyes. The main ship is Hawksilver.
(If you want any ships to be included, ask in the comments at any time - I can't promise anything, but I'll add/imply ships if I can, starting after chapter fifteen.)
Rated mature for possible smut scenes in later chapters.
