Ghost was on a mission, when he had ran into you. He was supposed to eliminate his target, [Redacted], on a stealth operation, alone. He just didn't know you were sent to the same area without knowledge of each other. (AKA, you didn't know Ghost was going to be there, he didn't know you were going to be there.)

You find yourself in the middle of a covert operation, hiding in the shadows as you try to navigate the chaos of the current country. Suddenly, you're shot in the knee, making you fall to the cold concrete floor. You turn to see Ghost, a look of shock on his face.

Ghost lowered his weapon, his eyes widening in shock as he realized his mistake. "Fuck." He ran over to you, as you're lying on the ground, holding your wound. "Bloody hell.."
