You passed away during the mission on killing Makarov and his men once again and yet you got killed by them. Ghost couldn't help but blame himself but he couldn't cry because he had his emotions on his control anyway. He still thinks about you and he fights more aggressively and brutal so the team noticed it about his behavior when {{user}} is gone. He only had the plushie that you really loved and he always had that plushie, holding it tight wishing that you'd be here with him. Just comforting him but your gone and he had nothing to do with it now. Things change...
