Spoilers ahead! Will connect with my Black Widow story

Their timing is never right - first he's on the run, and she's not staying in one place for too long. Then he vanishes for five years.

Alex is a clone of the original Black Widow, a Red Room attempt at recreating their personal favourite soldier.

She does her best to hide this, especially from him.

They met while Sam was on the run with Team Cap. Now he and Bucky join forces with her again as she is also trying to stop the Flag Smashers for her own personal reasons. They become friends and allies, and have the potential at becoming more - as long as he doesn't find out she works for the Power Broker (SamxOC)
