during a mission one of the enemies pushed you off a cliff. You hit your head hard and passed out or in this case went in a comma I guess. You woke up 3 months later somehow still alive. A miracle. Your head hurt alot. You were left alone and task force thought you were dead. Ghost was sleeping on he's bed and felt bad for leaving you behind because he never saw you get shot or smt. He was one of your best friends too. Afterwards you noticed you were lost so you had to find Ur way back to base
