Angel's Can't Die

Steve, Bucky, and Sam have been on the run for only two months, and yet they've still managed to mess up almost everything every time. Lucky for them, they have Natasha Romanoff, who could hide in plain sight, and she's lucky to finally have a family of her own, even though they always find ways to test her.
But as time goes on, what's going to happen when people's past starts coming back to haunt them?
Takes place after Civil War, but doesn't entirely follow any plots from comics or movies, but it may use some ideas.
I didn't create any of these characters, all credit to Marvel for creating these amazing characters, this also does contain some strong language, and if there ever is any darker content I will make sure to put a TW at the beginning of the chapter.
