*ALL GENDERS* Y/N knows who they are. At least, they think they do. Joining the Avengers was supposed to mean missions, training, questionable decisions, and learning how to survive living with Earth’s most dysfunctional group of heroes. It was not supposed to turn into a decades-old mystery involving HYDRA, the Red Room, and two people Y/N already knows far too well. Natasha Romanoff once had a child she was told died. Bucky Barnes never knew he had one. And Y/N has absolutely no idea that either fact has anything to do with them. None of them know the truth. For now. Because some secrets stay buried forever. Others start with one medical result that doesn’t make sense.
