From the Lifestream, all things originate, and to it all things return. Meaning people are knitted together from spare fragments of spirit energy, go live in a crappy world, then when they die, their spirit and consciousness is completely dissolved bit by bit and the cycle starts again. Then there's the fact that even as a living being, contact with raw Lifestream results in mutations, insanity, and other unspeakable things.
Also, that lightbulb in your room? Powered by your dead grandfather's soul courtesy the ShinRa Electric Power Company.
Also, what happens to Grandpa's soul once it has been used to power that light bulb? Is it thoroughly spent? Is it trapped somewhere? Think about it. Or better yet, don't.
Not exactly Fridge, since there's a cutscene where Bugenhagen shows you a simulation/vision of all the Lifestream drained from the world, leaving it a lifeless rock...
I would disagree there, I think he's quite right about it being fridge- the point isnt about what happens when the whole lifestream is gone, it's what happens to the part that was your grandpa's soul. After all, the energy in a light bulb is released as light and heat, so those photons energised by ol' grandpa? Flying off into space, perhaps? Dissipated into the air across millions of square metres, never to rejoin the planet? Fridge indeed.....
Grandpa's soul wouldn't even have reached the lightbulb. It was already burned in an atomic furnace to create normal electricity.
Natural materia is quite rare, and with good reason: it's formed from the condensation of Mako over the course of many many years. Materia can be manufactured too, though it's said that man-made materia is less powerful than natural. Materia allows you to focus and call upon the powers of the land, or so they say. No matter how you slice it though, materia is spirit energy balled up into a crystal and used to perform magic. If you've ever used materia, you're a necromancer.
Another spooky thing about Midgar: We all remember the scene where ShinRa blows up the support beam holding up Sector 7, right? And how Reno mentions how its self-destruct is set to go off if anyone messes with it too much...while this was undoubtedly to prevent anyone from messing with it once they'd set it to get ready to blow, this opens a whole other can of worms. Think about it: A team of 8 people could get to each tower's control unit, goof around mindlessly a few times, and completely wipe out the entire city.
What he's saying is that if the heroes mess with the self-destruct that he just activated it will go off. Not that if anyone just futzes around with the console on a normal day it'd go off. That'd just be stupid. He's describing the current, specific circumstances, not how it always works.
Hell, just to take that bit of FH one step further: Why the hell were the primary support beams designed to be able to self-destruct in the first place!? Thank goodness nobody in this world thinks like that when designing major cities....umm, they don't, right?
Worse still: A member of your party is Shinra's Head of Urban Development!
Even worst; when ShinRa caused the plate to fall they killed two towns worth of people just to get at a group of six. This at first sounds like ShinRa holding a Villain Ball, until you realize how Mako works; they were refueling.
Aerith works as a flower girl. Sweet and innocent, right? Until you find out that "flower girl" has been used as a euphemism for "prostitute" in certain cultures, including China, and you think about where she works, and wonder if her price of 1 gil a bloom is enough to make the rent, and think about how readily she agreed to date Cloud, and how comfortable she was pretending to work at the Honeybee Inn, and...well, it's WMG, but let's just say the poor girl might have had more than aphids to worry about...
If you talk to some of the men outside the Honeybee Inn after Cloud enjoyed the company of 20 burly men (or just had a freak out, depending on which room you went in), you find out that Aerith sold some flowers to them for 500 gil. Maybe not a prostitute, but definitely a tease.
One of the men also says that Aerith told him that she wouldn't go out with him even for 1000 gil! It's actually more Fridge Brilliance than Fridge Horror in that it's Aerith'slittle joke. Aerith presents herself as a "flower girl", and if men take that the wrong way, she charges them lots of gil to "buy her flowers." (Remember when she was clearly literally selling flowers towards the start of the game, so only charged Cloud 1 gil.) And so when it turns out that she really was just a flower girl and not THAT kind of flower girl, it's too late for the poor horny guys to get their money back!
Building off of that, in the film sequel Advent Children, the villains bring all the sick kids to the Forgotten City and have the kids drink from the water there. And then you remember that Aerith's body has been down there decomposing for the past 2 years. Ewww.
...Or rather, her body and soul became part of the Lifestream. That water's clean. ...Well, until Kadaj... does that weird black inky thing to it.
"Peeing in the water", as this troper's friend put it. Let that sink in...
Even more strange is the way Cloud is clearly standing in the water, but as soon as he lets go of her, she sinks at least a few meters to the bottom.
How did Lucrecia find out she couldn't die, she tried to kill herself.
There's the Hell House, an enemy that is powerful for its early appearance in the game in the Sector 6 slums. It looks like a fairly innocent house, but rams and guns down those who attempt to approach it. Do sufficient damage to it, and its innards pop out, which include a skull-like head and several arms. The horror becomes apparent when you remember that most people in the Midgar slums live in appalling squalor; Many live in shacks constructed of scrap metal and abandoned equipment. The Hell House seems to take advantage of this by luring its victims to what appears to be an actual, well-constructed and pleasant house.
There's the moment when, after you've been taken prisoner by Shinra, you wake up to find all the guards brutally killed and the door to your cell unlocked. One of the guards' corpses is just to the left of your cell. Sephiroth was right outside as you slept. He may very well have been the one to unlock your cell.
Rufus Shinra's Heel-Face Turn is actually foreshadowed during the game. Despite his talk of ruling the world through fear he expresses nothing but disgust towards the monsters his father had placed in charage of Shinra and likely would have replaced them once the crisis was over, he never commits any acts of mass murder while several happened under his father's orders. The biggest however is easily missed, after Tifa wakes up after the incident at the Northern Crater Rufus sentences her and Barrett to be publicly executed. The foreshadowing? He apparently let the rest of the team go, Barrett and Tifa however are terrorists responsible for the deaths of hundreds of innocents from their bombings of the reactors, they deserved a death sentence anyway so Rufus only punished the people who actually deserved it.
So you know how when a Materia's level maxes out, the original Final Fantasy VII will spawn a new materia and tell you "X is born!" I thought that was a result of the "Blind Idiot" Translation...but think about it. Materia is make of Mako, and Mako is the LIFE of the Planet...so that means that whenever a materia spawns a new one, it is literally giving birth, amoeba style. Nice one, Square Enix.
The first time Cloud tells the story of the Nibelheim incident there's a lot of little foreshadowing tidbits that you cannot but notice on later playtroughs, namely:
Cloud's POV during the train scene is evidently Zack right until Sephiroth starts talking about Nibelheim being "your hometown". Although the speech bubbles still come from "Cloud", the dialogue is from the real Cloud (the sick grunt).
In that same scene Cloud starts doing squats when he gets excited. Which is a Zack mannerism that the real Cloud never displays IIRC.
Sephiroth tells Cloud he can go visit his family and friends right at the moment in which a grunt enters from the left side. That grunt is actually the real Cloud, who is who Sephiroth is addressing.
For someone who left only two years ago, everybody in Nibelheim sure takes a bit too long to recognize Cloud. Evidently, it's because of the helmet in his grunt uniform.
Cloud's Mom asks Cloud if what he's wearing is a SOLDIER uniform, presumably with excitement, and Cloud replies "Mom, I...", presumably embarrassed at her delight. Actually Cloud's Mom's question is probably she sensing that something went wrong because she sees it as a "low rank" uniform, and Cloud's embarrassment is about his failure. That's why Cloud's memory has so many blanks in this part; a good deal of the conversation was probably about Cloud's failure. You probably thought sometime that Cloud seems weirdly uncomfortable being around the mother he should have been eager to see.
Either that, or his mother was never there to begin with; she's the only person in the current Nibelheim town who doesn't have an actor to take their place and can't be accounted for elsewhere in the world; plus, when Cloud finally gets back around to himself, he never even mentions her. But, we do know that Zack had loving parents in Gongaga. Cloud probably "remembered" going to visit his mother because going to his parents' house is what Zack would have done.
That makes no sense. Cloud talks about his mother being killed there.
Tifa asks afterwards if she was very hurt when Cloud found her. Your first reaction is to think whether she didn't remember the details of what happened. On the contrary, she is beginning to think that Cloud has assumed Zack's role in the story and is asking him something that only the person who attended her would know - just to affirm her suspicions that the real Cloud was the grunt she remembered being with them, and to see how much of the real Cloud is still there. Her constant interruptions when Cloud is visiting her house might have something of this as well.
Another possible interpretation is that she was, at the time, doubting her own memories and trying to make sense of what actually happened. Sure, Cloud clearly wasn't well when she found him, and she was sure he wasn't at Nibelheim... but she had been badly hurt, he knew things he shouldn't have unless he was there, and our minds do have a funny way of messing with our memories. IIRC it's not until they're in the Lifestream that she realizes Cloud was the grunt.
The ending, or rather the complete lack of one. Cloud cuts off once he and Sephiroth face down in the reactor and doesn't elaborate further. He doesn't believe for a second that he could have killed Sephiroth, but Cloud obviously didn't die either. All anyone knows at that point is that Shinra has officially stated that their best SOLDIER is dead. They're correct. And Cloud did it.
The reactions of everybody after Cloud tells the story: Tifa asks for a small detail, as discussed above. Aeris dodges Cloud's personal issues and changes the subject directly towards Sephiroth and the Ancients. She probably suspected she was seeing Zack inside Cloud since some time and Tifa's small questions probably confirmed her doubts. Barrett says the story doesn't make sense. He's right. Red XIII says "What a fascinating story". Which doesn't imply he believes any of it.
If you date Aerith at the Gold Saucer, she and Cloud have the following exchange (which, in hindsight, is a hint that she knows that Cloud has adopted Zack's personality and memories as his own):
Aerith: Cloud...I'm searching for you.
Aerith: I want to meet you.
Cloud: But I'm right here.
Aerith: I know, I know....what I mean is...I want to meet...you.
When Shinra opts to drop the Sector 7 plate onto the slums, it seems like overkill to take out an Oddly Small Organization, and demonstrates just what a ruthless pack of immoral bastards most of the higher-ups are. And then we remember that it happened not long after Cloud presented himself to the president as an ex-SOLDIER. Crisis Core showed that SOLDIERs are so Badass that they needed to send a small army in just to deal with one who had gone rogue. As far as Shinra is concerned, AVALANCHE had crossed the Godzilla Threshold by taking in a rogue SOLDIER.
If you look at Aerith's profile in FF7 website you will see that her blood-type is O. People from this blood group are known as "universal donors", meaning that they can donate blood to people from any blood group. It fits as a fiddle with Aerith always giving the best of herself for the good of the planet, specially with her death.
On the other hand, Cloud's blood-type is AB, making him an universal recipient.
