Agent 13

What if HYDRA did more while hidden within SHIELD? What if, with new technology, they continued to want more? To always take it one step further? What if HYDRA had another version of the Winter Solider hidden so well within SHIELD, HYDRA themselves didn't know the programming worked? If HYDRA didn't know, how could the Soldier herself know?

Years after the fall and rebuilding of SHIELD, Fury starts to uncover just how deep HYDRA's teeth sunk into SHIELD. Some of them include old founders, great-nieces of old founders, and old enemies. As agents of the rebuild SHIELD start to mysteriously vanish, Fury knows that they need to get to the bottom of this, fast.
