Big Boss, dying in the graveyard: Anyway, now that we've established that you didn't really fight me in Outer Heaven.
Old Snake: That's horseshit, but okay.
Big Boss: I'm surprised your friend Hal turned out okay. His dad was a real prick.
Old Snake: All I know is that he was born on the same day as Hiroshima and he possibly drowned himself in a pool because he found out that Otacon was sleeping with his new wife.
Big Boss: Oh. Well...
Old Snake: Otacon beats himself up over designing REX and causing all that and shaming his father into death.
Big Boss: Oh, well it's good I'm here then, you can tell him that neither of those are really his fault.
Old Snake: what the fuck now
Big Boss: His dad actually built the first Metal Gear that was basically just an anorexic REX, then he built another one that was REX but it could stand up like a person and had a sword and whip. Little Mantis controlled that one but it had a cockpit for little kids only.
Old Snake: what
Big Boss: Yeah, Hal probably stole all that shit. Didn't do a thing, really. Anyway, Huey - that's Hal's father, by the by - probably killed himself out of the shame of setting my mercenaries up to be slaughtered like twice, then helping a bad guy named Skull Face, then wanting to put Hal in the cockpit of a Metal Gear as a test subject, then killing Hal's mother for not wanting that last part.
Old Snake: Otacon has been tormented by the knowledge that he indirectly killed his father for decades. Which is kind of familiar, but I'm having second thoughts about the regrets part.
Big Boss: Nah, Huey was a huge asshole, it's fine.
