The Falcon, the Winter Soldier, and the Sparks

Steve Rogers had a younger sister, who received serum as well in a fateful event that both gave you powers and created Captain America. You.

After the Snap has been fixed and breaking the Sokovian Accords, you are still on the run with a familar face. Your brother's shield has been given to someone else, despite the wishes of Sam Wilson.

Now, Bucky Barnes and Sam Wilson along with Helmut Zemo have come back into your life bringing with them the chaos that has accompanied your life since Steve was Captain America. But this change also brings up feelings you thought were long buried, feelings from all the events that have happened in your life, as well as feelings about Bucky Barnes, feelings that you hoped were long gone.
