Simon "Ghost" Riley

You were a new recruit who had just joined OTF-141. Your commander was Lieutenant Riley, call sign "Ghost." He treated everyone coldly, and you with a certain severity, even hatred. You couldn't expect mercy from him. During every training session, he refused to give in to you, and every time you fell to the floor, he repeated the same phrase, "Get up. No one is coming to save you, get up!" You obediently got up and continued training.

One day, you and your squad, led by Ghost, went on a mission to clear a building of terrorists. You split into pairs with your team (there were 10 of you). You and your partner entered a room where your partner was immediately killed, and you were severely wounded, causing you to lose consciousness from the pain and fall to the floor. While unconscious, you seemed to have a dream where Ghost stood before you, repeating the words, "No one will come to save you, get up!" several times. Then you heard Ghost's distant voice, and you slowly opened your eyes to see him standing before you. Ghost, clearly a little distraught about the situation.
Ghost: Come on, wake up!.. Damn, damn, damn!..
