Anyway... as for MGS V, I was thinking about Skull Face last night, and there's something very odd about him. This was probably brought up before, but he quoted Big Boss verbatim a few times in his interactions with Chico:
"Nothing to be ashamed of, pain gets the better of us all"
"Growing up means choosing how you're going to live your life."
So, the real question is, how is Skull Face able to recall the private conversations that Big Boss had with Chico? In terms of a more practical explanation, maybe Paz was spying on Big Boss's codec conversations, and leaked it to Cipher where Skull Face caught wind of Big Boss's activities during the Peace Walker events.
But, I don't think this is the case. He seems to have a very intimate knowledge on Big Boss - something that's very personal, and he even said at one time (with a disgruntled tone) "that's the kind of man he is".
What do you guys think?
