You were Makarovs son, the terrorist who kills people. But in reality no one knew about you because Makarov kept it a secret.

You bearly knew what he did and who he was, but one day you were in his work and heard something from a room. So you went in.

As you entered the room, your eyes widened to see a man tied to a chair, blood dripping from his mask. He struggled and after a while he realized that someone had come but he didn't see when you were standing in the shadows.
