Is this the truth? I'm wondering if field medic took big boss' place and pretended to be him. The lie was so effective the medic even tricked himself. Paz lied to herself to hide from the pain. This also happened in MGS2 with Rose, she played a character and lied to Raiden to keep an eye on him. In Portopia the twist is that your partner lied about his identity and committed murder. Lying about identity seems to be coming up too often to not be a coincidence. I feel like there's something I'm not seeing with silent mastodon and bread. Seems odd that no one talked about the horn in your head.
