[[folder: Fridge Brilliance ]]

* David Hayter is mocked for his line "You were the lightning in the rain. You can can still shine through the darkness" he gives to Raiden. The truth is that it completely fits the situation as Raiden stands for "lightning bolt." After the revelation that Raiden used to be Jack the Ripper, Raiden stated he found himself unsuitable to live a proper life as he was a killer. However, Snake states that back in ''Solid 2'' Raiden stood out in Big Shell as Raiden, not Jack the Ripper. Raiden appears to accept Snake's claim later as he says "I am lightning. The rain transformed." when he saves Snake from the FROGs.
* Everyone likes to complain about the whole "nanomachines being used to explain everything in Guns of the Patriots". But in an example of CompletelyMissingThePoint, the reliance of nanomachines is a big part of the game's story. PMC's and the Rat Patrol 01's reliance on nanomachines show the dark future ahead and how lost they are without them. People disregard their own SENSES ([=MGS4=]'s major theme) in favor of technology.
* [[spoiler:The identities of the Patriots being Naked Snake's former support crew from ''VideoGame/MetalGearSolid3'' seems like a bit of an AssPull, until one realizes that it was Major Zero who coined the name of the organization, as well as the use of the term "La-li-lu-le-lo" (although the Director's commentary in the aforementioned game mentioned that "patriots" in that case were more a reference to the term rather than the name of the organization). It's also worth remembering that they aren't revealed to be the Patriots anyway, only the founders; it's just that the ''current'' Patriots, the AI system, aren't seen after the end of ''Sons of Liberty.'']]
* One of the more subtle callbacks of the game--when Raiden makes his first appearance, he holds his sword out in front of Snake and Naomi in exactly the same way that Olga did when saving him in the second game. As if to say "You will go no farther."
* Also, in ''VideoGame/MetalGearSolid3'', The Boss made EVA and Ocelot swear never to kill nor aid in killing Naked Snake (the former was explicitly stated whereas Ocelot was more implied). When taking that into account, it's really no wonder why EVA and Ocelot ended up betraying (the former openly, and the latter covertly) the Patriots and attempting to destroy them after Zanzibar Land.** The nationalities of the three most prominent founders of the Patriots ([[spoiler: Big Boss (American), Revolver Ocelot (Russian), and EVA (Chinese))]] corresponds to the three countries that founded the Philosophers. This is fitting, since [[spoiler: the Patriots used the Philosophers as their cover to make it look like they had been around longer than they really had]].
* Since Liquid was a clone just like his brother, he would have eventually fallen victim to the same accelerated aging that Snake did. This means that had Liquid survived [[VideoGame/MetalGearSolid the Shadow Moses takeover]], he would probably look a lot like the seventy-something year old Ocelot does in [=MGS4=]. When you think about it, this makes Ocelot's masquerade just that little bit more believable: he looks just like Liquid would look if he were still alive.
* [[spoiler: In ''VideoGame/MetalGearSolid3'', we learned that Major Zero is a huge fan of the ''Film/JamesBond'' movies. Here, we see how much he resembles a James Bond villain himself. He's an affable, witty British man with an evil-looking scar over his eye, and he takes over America with supercomputers. But unlike a classic Bond bad guy, his plan actually succeeds. His Bond-like nemesis (Big Boss) doesn't defeat him until over fifty years later...when he's an invalid old man, and he only needs to unplug his breathing machine. Maybe watching all those Bond movies make him GenreSavvy enough to succeed]].
* In Chinese Big Boss translates as Taipan, which is also the name of a group of the most deadly poisonous snakes in the world. (Though it's unknown if this was intentional).
* This game represents Kojima's last attempt to duct tape every errant thread in the cloth of the pre-existing Franchise/MetalGear continuity into a coherent whole, therefore an iota of contestable confusion was inevitable. That there aren't more is a testament to Kojima's writing skill.
* Jack (Raiden) was presumably named by Solidus. Therefore, Jack was probably named after the diminutive form of Big Boss' real name.
* The question has been asked as to why ''Snake'' has to go through the Microwave Hallway at the climax of the game, since it certainly appears that the Mark III does all the work anyway. Simple: the door at the end of the hallway (not the big one that Mark III unlocks, but the one before that) opens automatically, and it ''doesn't respond to something as small as Mark III''. Snake needed to be the one to deliver Three to the to GW core, simply because the door at the end of the hall had an entirely sensible method of preventing infiltration by remote-controlled drones.
** The impression I was under was that Snake had to be there to protect the Mk. III. How was Snake going to know that there wasn't going to be something that could destroy Otacon's drone? Snake's assistance was necessary because otherwise the drones that shock him would have destroyed the Mk. III.
* Snake's support team in Metal Gear Solid chide him for harming himself by smoking. When he said he didn't care about the risks of smoking compared to the risks of being a soldier, they responded that he hurt others with second hand smoke. So in [=MGS2=], he has cigs that give off no second hand smoke. When Otacon complains that he's still littering with his cigarette butts, Snake starts to carry around a portable ash tray in [=MGS4=]. [[spoiler:And after his life is free from battle, ''he quits smoking altogether.'']]
* Some consider [[spoiler: Naomi's death after stoping her nano-machines to not make any sense, since she died very quickly afterwards.]] But the [[AllThereInTheManual [=MGS4=] database]] manages to fill in the blanks. [[spoiler: Her nanomachines only work around injuries, healing things only to the point that their whole, but not very healthy as we saw with Vamp. Naomi was one of the new targets for Foxdie, and contracted it as soon as she met Snake in the Middle East. But because of her nanomachines her heart kept working even after FOXDIE went at it. Once their stopped, there's no work around for the fact that most of her organs are cancer-damaged and she has another set of nanomachines eating away at her heart. It's even subtly implied in the game itself; when Big Boss says that FOXDIE killed Eva and Ocelot, the flashbacks show Eva, Ocelot and Naomi.]]
** Can someone explain where exactly it was stated that Naomi was one of the second FOXDIE's targets? The FOXDIE article on the Database only covers the first strain.
* The Beauties. At first I thought they were [[FanService cheesecake]], but then I realized that the contrast between their attractive outsides and their horribly, horribly damaged insides made them even creepier. -{{Tropes/Jonn}}
** Laughing Octopus did that for me- during the second playthrough, her lines about people hurt and dying being hilarious sound ''much'' [[NightmareFuel creepier]] when you know what she was [[BreakTheCutie forced to do]]. -{{Regiment}}
*** Additionally, they thematically fit with the growing themes of nature vs technology in the series. Compare and contrast say, Crying Wolf with The End. One is a sniper with an almost symboitic relationship with nature and uncanny talent which was honed through years of developing technique. The other is a machine mockup of an animal who barely adheres to proper tactics because the technology that made them allows them to do so. It goes on. Compare how the Fear could run on water to how Vamp is eventually theorized to. Or just Fortune's powers in general. The progression of bosses in the series (chronologically) traces a shift between natural talent with a tad of mysticism tossed in to full on, technologically dependent, VR trained soldiers.
*** How about the fact that Old Snake's namechange makes him fit the naming scheme of the Beauties? Snake was the other member of FOX-HOUND, and the 'emotion' he carries into battle is "End", signified by his "Old"-ness. He used to be gorgeous, but now he's ugly and dependent on his suit to fight. Makes Drebin's suggestion that Snake's just like the Beauties a bit more than just a generic NotSoDifferent line.
** This Troper saw the "Octopus" advertisement as an interesting aside. However, in the codec conversation about it, Snake mentions that you have to use what you have. Octopi are some of the most adaptable creatures in the ocean. And how do the members of the Beauty and the Beast Corps adapt? By using nanomachines! The ad has a second layer, saying that adaptability is better than raw power. This sums up the gameplay of ''Franchise/MetalGear''
* It took me until my second playthrough of the fourth game to realize that, likely as a byproduct of the nanomachine control or similar, that some people are unable to hear or speak The Patriots as such and can only say or hear it as a bunch of garbled letters - La Li Lu Le Lo. It made the president's confusion at Raiden in the second game make a lot more sense, too.
** It's worth noting that A-I-U-E-O is the way that many East Asian nations learn their vowels and the combinations of consonants and vowels. To Japanese players, this is most likely seen as the Chinese way of learning L sounds as a child.
* In [=MGS4=]'s microwave hallway, one of the sequences on the top of the screen near the end is Sunny making eggs, and being happy at the result. It was a sharp contrast to every other scene which were 'sad' and 'downers', but then I remembered one of the conversations Sunny had with Naomi. It was her "sunny-side up fortune telling" - if the eggs came out well, something good was going to happen. And as such, something good ''did'' happen: the Patriots were destroyed, and the entire conflict ended.
* Cynthia wasn't her real name. It's a reference to a real spy. Call Zero after the cutscene.
* At first, the revelation that Major Zero and Naked Snake's support crew were the founders of the Patriots seemed like a random retcon in an attempt to shoehorn the supporting cast of ''Snake Eater'' into the Patriots conspiracy in ''Sons of Liberty''. But if you go back to the beginning of Operation: Snake Eater in ''[=MGS3=]'', the password Zero tells Snake to use on ADAM was "Who are the Patriots?" and "La-li-lu-le-lo".
** I kind of felt the opposite way. Like the cast of Snake Eater was created specifically because Kojima didn't know where he had intended to go with the Patriot's storyline before then. Since he hadn't intended to make another MGS game after 2, he created these characters in 3 specifically so he could have a twist to reveal in 4.
* In the second game, Otacon almost exclusively referred to his stepsister Emma as "E.E." Emma's wish was that Otacon respect her as a woman and refer to her as "Emma," which he [[spoiler: failed to honor before her death]]. Come the fourth game, he only refers to her as Emma; not once is her old nickname referenced.
* So I was listening to [[http://www.youtube.com/watch?v=lGf2b1H91JA Love Theme]]. It's got a very, ''very'' slow tempo, but it has a pattern of building up tension, pausing, then releasing all that energy in one euphoric go, gathering more and more tension as it goes (go to 3:50 for the climax of the song to see what I mean). Eventually I noticed that when I listen to the song, I actually breathe in time with it, breathing in as the song goes up and breathing out as it goes down - i.e. the song is basically ''sighing'', which fits the weary tone of the game fairly well. However, the true Fridge Brilliance came when I realised this matched up perfectly with Snake's smoking habit.
* The Patriots were composed of five AIs. Four (GW, TJ, AL, TR) are named after four famous American presidents, the ones that are engraved into Mount Rushmore (George Washington, Thomas Jefferson, Abraham Lincoln, Theodore Roosevelt), and the fifth is JD, which supposedly stands for John Doe. So what's the Fridge Brilliance here you ask? It may be unintentional, but JD is also the initials of Jefferson Davis, first and only President of the Confederate States of America.
** I thought it was because [[spoiler: John Doe is stated to be Big Boss' real name in MetalGearSolid3.]]
* There's also some fridge poetic justice in the USS Missouri, a ''WorldWarII battleship'' and a bunch of Marines and sailors, themselves without the benefit of SOP, taking on Outer Heaven [[spoiler:and ''winning'']] while Snake does his job. The ship and soldiers represent in a sense the world as it was before Zero, Big Boss and the Patriots got into the picture. [[spoiler:And once all of them are out of the picture, humanity would effectively be brought back figuratively to that point in history to move forward. Although as ''Revengeance'' reveals, that doesn't exactly stop business from going on as usual, albeit without the Patriots' influence.]]
* The symbolism of Big Boss killing Zero is rather ironic if you think about it. Zero made FOX and Big Boss made FOXHOUND, and as we all know foxhounds are specifically used for the purpose of hunting foxes. In that sense Big Boss (the FOXHOUND) killed Zero (the FOX).
* The flashbacks we experience [[spoiler: during the final battle with Liquid Ocelot? They're Ocelots own memories between his Liquid person and his true self gradually returning to him.]]

[[folder: Fridge Horror ]]

* At the end of the game [[spoiler: Snake has destroyed the Patriots, but that does not mean the Metal Gears have been destroyed and nothing will stop them from being rebuilt as long as the blueprints are still around. This was Snake's last hurrah, I don't want to live in a world without Solid Snake!]]
** Very oddly confirmed in ''VideoGame/MetalGearRisingRevengeance''. Gekkos and Metal Gears still continue to be made, and war continues like business as usual. [[spoiler: And the most Snake can do is have his soul empower a wooden, non-lethal sword for Raiden to utilize, as a bonus weapon that has no bearing on the story.]]
* After being defeated and either sleeping or dead, Crying Beauty is taken away by a wolf. It's all very symbolic given that she was known as Crying Wolf and all, but what normally happens to people taken by wolves...?
** Made somewhat better by the fact that the wolf that picked her up was rumored to be the spirit of Sniper Wolf. She's likely carrying her fellow Wolf to a peaceful resting sight.
