i'm going to go full on spoilers so if you haven't finished every MGS game up to this point then do not read post.
Kaz Miller is killed by Big Boss
Paz is not dead.
Ishmael is Paz's son
Eli is Gray Fox / Frank Jaeger.
"Phantom Pain" is the feeling you get from losing a piece of your limbs and not got used to not having it there IE "Phantom" feeling of pain that isn't there, Big Boss loses his arm.
Kaz and chiper (Major Tom) is using Big Boss for their goals , Big Boss then turns into a "Demon" "Serving in Heaven (outer heaven)" but he goes out of his way and kills Kaz and then Major Tom (in MGS4) turning his Outer Heaven back to Zero "Better to reign in hell than serve in heaven" - Paradise Lost
Moby Dick Project is Pacifica Ocean's (Paz Ortega's real name) creation and her son Ishmael to resurrect Ahab (Big Boss) from the dead, in order to kill Kaz and Cipher and the guns of the patriots.
Kaz means Destroyer of Peace, Paz means Peace, Peace mark is "V for Victory" Paz wants victory against Kaz and Cipher (Like Liquid Snake did) , and she gets it. V is not for Peace, but for Victory
