WMG: Return of the Jedi

R2-D2 mind-controlled the Death Star, wanting to destroy it more awesomely
This would explain why Luke, who was a great pilot, was on the strike team instead of piloting an X-wing. R2-D2 begged him not to, not wanting to destroy his own project in such a lame way as torpedoes, and probably intending to self-destruct it in an awesome way. Luke agreed, but the Rebels still went ahead with their own (generic) plan.
  • So, R2-D2 really was played by Pete!!!

The ending celebration montage takes place over several years
As someone pointed out on the "Just Bugs Me"-page, there's no way Coruscant - The Imperial Capital - would be in open celebration, only hours after the destruction of the Death Star and the death of the Emperor. Riots, stormtroopers everywhere, etc, seems more likely. The solution? The different scenes in the montage doesn't take place during the same time period. The shots of Luke and the others on the moon of Endor are obviously set only hours after the destruction of the Death Star, but the celebration on Coruscant could be months, or even years into the future
  • It's actually possible. See, for example, the initial uprising in Libya - Tripoli rose up, before Gadbastard sent in the aircraft. And a technologically-advanced society would be able to know that Palpatine was dead. The EU also states that that celebration ended with a brutal crackdown by the stormtroopers...

"Last of the Jedi will you be" is Yoda-speak for "You will be of the last Jedi"
So, more Jedi do exist, but there are so few of them. This might help reconcile all the Jedi that survived without making Yoda either a liar or misinformed.
  • "I am the last surviving member of the Grand Council, not to mention the most senior. So if you do this, you'll still be a Jedi, unlike those other jerks who use the Force and play with lightsabers without my blessing." Bloody "From a Certain Point of View". Alternately, replace the period in the original statement with a rhetorical question mark.
  • But doesn't "a liar or misinformed" describe every last Jedi we see on-camera in the entire series?
  • I'm sorry, but this WMG is not very grammatically sound. You have the clause "last of the Jedi", and then separately from that the expression of Luke being, the proper word order being "you will be" and Yoda's way of speaking going "will you be". Were Yoda to say what you were suggesting, the way he'd put it is, "Of the last Jedi, you will be," or, "Of the last Jedi, will you be."
  • I always thought that it was supposed to be a question "will you be the last of the Jedi?" makes perfect sense in that context.
  • Except there are no more Jedi. Force users, sure, but not actual Jedi. The handful of Jedi who escaped the Imperial purge did so by not being Jedi anymore. Some were corrupted to the Dark Side and became minions of the Emperor. Others just went underground and lived ordinary civilian lives.
  • In a novel, Ben tells Luke he's not the last Jedi, but "the first of the new".
  • Alternatively, (and I'm not to well-read in the EU, so take this with a grain of salt), if Yoda is indeed the last of the Jedi's Council and the Jedi Council is ruling body it seems to be, then Yoda's statement can be taken as a dissolution of the old Jedi Order, and a prosciption for Luke to create a new one. My evidence for this is that Luke does found a new Jedi Order, on Yavin 4, rather than the ancient Jedi temple of the old Order on Coruscant. Moreover, Luke rejects the philosophy of the old Jedi Order: he redeems the Sith Lord Darth Vader, rather than killing him as the two members of the old Jedi Order would have/told him to/tried to do(I count leaving someone without limbs to die on the edge of a pyroclastic flow, after they've caught fire, as trying to kill them).
  • As far as the movies are concerned, Yoda is telling the truth at that point. Between his death and Vader's redemption, then after Anakin's death, Luke is the only Jedi alive. On the note of the EU, while it supplements the movies, it is defined by the movies, the movies are not defined by it. If not including parts of EU make parts of the movies work better, it didn't happen.

Ewoks are eaters of their defeated enemies.
The Ewoks were completely ready to roast up Luke, Han, and Chewbacca for feast to honor their new god. While they get out of this unscathed, at the end there are quite a few Imperial helmets being used as drums, which makes you wonder what's the main course in the feast to celebrate their defeat of the Empire.
  • During the celebration, I sure hope our heroes warned their Rebel allies to stick to the salad.
  • This raises the question: are we talking already dead ones or live ones? 'Cause the Rebels took at least fifteen guys prisoner when they finally took the shield generator. I just can't see the Rebels murdering prisoners. So I think they could've given the Ewoks the numerous already killed Imperials, but I doubt they'd turn over the ten to fifteen guys they caught outside the generator.
    • Quite frankly, there's probably quite enough already-dead troops to satiate their appetites. Previously they were only going to eat Luke, Han, Chewie... and R2-D2? (Good luck to them if they'd tried!)

Palpatine threw the final battle.
If you watch the battle among Luke, Vader, and Palpatine in the second half of the movie, you come to realize that Luke would have turned to the Dark Side instantly if Palpatine had just shut his mouth. This could have been Obfuscating Stupidity and the Villain Ball that he was carrying for the entire movie, or it could be that he had had enough of the Dark Side and wanted to die. (Then again, given how he spends the entire EU trying to come back, it was probably just the Villain Ball.)
  • Or he's just lost it. He's not exactly very bright in that movie.
  • I reject this for the same reason I reject the theory that he threw his fight with Windu: he's just plain too proud. A master manipulator like him could easily find a way to accomplish the same things without having to suffer humiliation or harm, and he would never allow himself to end up on the short end of the stick to the pitiful likes of...well, anyone, if there's anything at all he can do about it.
  • Palpatine didn't want Luke to fall to the dark side. He wanted Luke to fall to the dark side and become his apprentice. The last fight with Vader started with Luke attacking Palpatine and Vader trying to stop him. In other words, Luke is fighting Vader in defiance of Palpatine. If Palpatine said nothing and let Luke kill Vader, then Luke is killing Vader (Palpatine's apprentice) in defiance of Palpatine. He may have fallen, but he would have become a Dark Jedi rival to Palpatine. Even if Palpatine was certain that he was more than powerful enough to destroy Luke in that situation, in the end he would have no apprentice. So he had to interrupt when he did. It was a test of Luke's loyalty. Now, if Luke kills Vader, right after Palpatine tells him to, then that act would be one of obedience and submission to Palpatine. Only then would Palpatine be sure that Luke is falling and becoming his loyal apprentice. If Luke remains defiant and refuses to kill Vader, then Palpatine would kill Luke, and he gets to keep Vader alive as his apprentice. There was nothing, nothing, stupid about Palpatine's actions and words there. It was all deliberate and consistent with his plans to that point. His only mistake was not anticipating that Vader would turn on him for Luke's sake. His arrogance was in his assumption that his manipulation and breaking of Anakin Skywalker was complete and irreversible.
    • Oooh, great point.
    • Nah I think Palpatine was really arrogant. It seems that perhaps to service the force he wishes to get Luke to give into his hatred, get more powerful, and in his anger turn to the dark side. Which might have had a chance of working if the Emperor could've kept his gob shut for five seconds.
      • In Palpatine's defense, he has reason to be arrogant: the guy has had everything go swimmingly for him for the past 36 years, and unlike most worlds-ruling tyrants did it through unmitigated skill instead of sheer power. If that doesn't cause a tyrant to lapse into Smug Snake territory, I don't know what would.
      • Palpatine had been using the Force to see the future since way before the Phantom Menace. The point of the Battle of Endor was never to destroy the Alliance, but to turn Luke to the Dark Side; the Rebels were a powerful propaganda tool for the Empire(kinda like Al Qaida and Hamas are in our world). He followed the path the visions showed him right up until Luke refused to kill Vader, which he hadn't seen. Enraged that decades of planning hadn't gone the way he'd forseen, Palpatine decided to have an electric tantrum on Luke; but, like Voldemort, the Emperor didn't understand how love really worked...

The Sarlacc is a larval space slug.
Back in The Empire Strikes Back, we saw a gigantic worm-like creature which tried to eat things and had a breathable atmosphere inside it, in an asteroid field that looked kind of like the results of the destruction of Alderaan (so it might originally have been on a planet). In Return of the Jedi, we see a smaller worm-like creature that tries to eat things; it was on a planet with a breathable atmosphere, no vegetable life, and a lot of Dune references. In Dune, the sandworms provided the atmosphere of Arrakis, and the atmosphere of Tatooine has to come from somewhere.

Also consider that the Galaxy Far, Far Away is home to a very large number of very nasty organizations, all of which are eager to inflict the most horrible deaths they can on their enemies, but only one of them, and evidently not one that's exactly on the cutting edge of things like scientific knowledge and military equipment, uses the Sarlacc for executions.

Thus, the Sarlacc is a larval form of a space slug, and space slugs are terraformers originally created by the Rakata or one of the other species of Precursors that the Galaxy Far, Far Away is positively swimming in. Like a space slug, it eats anything that gets close, but it digests things over a normal, less-than-a-thousand-years timeframe — it needs the biological molecules. (It can probably also handle metals and use those for structural purposes as well; it must get its energy from an internal cold-fusion reactor or thereabouts, as neither the Sarlacc nor the space slug had a diet that would provide enough energy for its extreme activity level.)

Ask any xenobiologist, and he can tell you as much — and can probably give you a DNA sample and tell you where other creatures of the species are located, how long they take to mature, how long it takes a mature one to transform a desert wasteland into a comfortably habitable planet, and whether they die after the end of their Roaring Rampage of Terraforming or whether you have to kill them.

Jabba, of course, was too clever for the xenobiologists and asked the local Jawas instead, explaining why he's the only person in the galaxy who throws people into the Sarlacc as opposed to inflicting some other, more conventional, form of horrible death.

Its form as depicted in the original version of Return of the Jedi is a very "newly-hatched" stage, where the characteristic space-slug mouth is still developing; its form as of the Special Edition (which was what Lucas wanted to do to begin with, although he didn't have the budget) is a later-stage juvenile space slug.

The Ewoks are the most bad-ass race in the Galaxy.
They're willing to take on enemies with far more advanced weapons, like AT-S Ts and blasters, which takes guts. They are able to create huge suspended villages and set up effective traps in a short amount of time, which shows good planning and discipline. They aren't afraid to use unfamiliar technology, which makes them adaptable. And finally, there appears to be thousands of the little buggers, which could indicate rapid breeding. If they ever get off planet, they might start their own empire.

The Sarlacc is actually an Eldritch Abomination that serves as a portal to Hell, and the people telling otherwise were making the whole thing up
Hence why the people who falls in there will be in great pain, for a thousand years, if not eternity. On the other hand, it's not just a thousand-years digestion, it could be worse....

The Ewoks are the Furlings of Stargate fame.
Think about it. The Ewoks created huge villages suspended from the trees, and fended off a troop of Imperial forces, armed with slingshots and rocks. A species with that much intelligence and skill could have easily been one of the four races if they had a stargate.

Simply Striking Down Palpatine Wouldn't Have Turned Luke to the Dark Side...
...and Palpatine is fully aware of that. Killing Palpatine would've effectively been something heroic, it would have saved the lives of millions, so it was only justified. However, Palpatine is a Magnificent Bastard, after all. Once he directly points out that he's defenceless (except for the electricity Luke probably doesn't know about) then it stops being outright heroric. Palpatine then messes with Luke's head. If Luke did strike Palpatine down, he would've gone to the Dark Side because he believed he'd fallen to the Dark Side, due to misplaced guilt and all that.

Imagine if Luke wasn't so lawful and was instead an Anti-Hero, and simply went "Shut Up, Hannibal!" and Force-pulled his lightsaber and chopped him down then and there. Would that really have dragged him to the dark side on its own?
  • Presumably if he tried at that point, Vader would have intervened, and the fight between them would have just started earlier (and if Vader didn't intervene in time, Palpatine surely could have Force-pushed or lightninged Luke to defend himself). Palpatine's plan was probably to provoke Luke into aggression, get him to start a fight, and let it snowball from there.

And of course, by making it seem like such a wrong thing to do, Palpatine pretty much guaranteed that Luke wouldn't kill him. Fortunately, Vader intervened and killed the Emperor.

Anakin brought balance to the force by killing Palpatine
The Sith is not what was causing the imbalance, it was Palpatine. So, with the death of Palpatine, the Force was brought into balance.
  • Actually it was the Sith. Basically, the idea behind the prophecy is that the Sith and the Dark Side is a cancer upon the Force. A balance isn't an equal amount of Sith and Jedi, it is the complete absence of the Sith. Anakin killed his master and in so doing died himself. He brought balance to the force yet was at the same time one of the things unbalancing it since he was a Sith, as there are only two true Sith at any given time, of which Palpatine was the master and Anakin the apprentice. His self-sacrifice killed his master and himself and brought balance. The prophecy wasn't misread, it simply came at a time when it wasn't expected.
    • Well of course the Sith are causing the imbalance: half of what they do is abusing life for their own benefit, and the Force is basically The Lifestream. The Force doesn't like people siphoning it off like that.
    • This troper always interpreted the prophecy differently. From what we know of the prequels, there were literally thousands and thousands of Jedi, whose vast presence in the Force was deeply rooted in the light side, and in a perfectly balanced system, especially in a duality like the Force, one side cannot exceed the other in volume and strength. The Jedi were the Sith, but on the extreme opposite end of the spectrum. The only difference was their values. Remember Obi-Wan's line in Revenge of the Sith? "Only a Sith deals in absolutes." That itself is an absolute, but from the other side of the coin. That's why the Jedi had to die, because the Force was not perfectly balanced under them either. And recall Kreia's line from Knights of the Old Republic: "For every Jedi slain, for every Sith slain, another will arise." This is a cycle of light and dark struggling to overpower one another that has been raging for millennia and will continue to do so until the universe eventually just burns itself out. Therefore, bringing balance to the Force is nothing unique. It's just part of the overall natural design in the Star Wars universe. It's the system correcting itself for an overflow it can't handle. If the Jedi truly wish to bring the Force into perfect balance, they need to be less rigid and inflexible in some of their ideals, and try to learn to incorporate the usually hateful aspects of the dark side into their teachings in a positive way, as we've seen many Force practitioners accomplish this successfully throughout the Star Wars mythos.
  • Or, it was balanced because Palpatine was the last Jedi or Sith in the galaxy. Remember, Yoda told Luke he wouldn't be a Jedi unless he killed Vader, and he didn't. The Jedi were the action, and the Sith were the equal and opposite reaction. Both authorities are now eliminated.
    • Nope, Yoda said he wouldn't be Jedi unless he confronted Vader, which he did. Plus Luke actually says "I am a Jedi."
  • Palpatine wasn't the last Jedi or Sith. Luke was. He became a full Jedi when he defeated Vader and turned him to the light side. That meant Palpatine was the only Sith left, and Vader killed him. No more Sith = balance was restored.

  • Alternatively, Darth Vader did bring balance to the Force...in Episode III. Vader(under Palpatine's order's but still) destroys the Jedi Order. Eventually, we see in the movies only two surviving, Obi-wan and Yoda. After Obi-wan dies, Luke becomes a Jedi, so that there only two Jedi left...a master and a apprentice, just like the Sith. 2 = 2, the light side of the Force is balanced with the dark side of the Force.
    • While there are others besides Vader who kill off the Jedi over the gap between episodes III and IV, such as clone troopers, stormtroopers, bounty hunters, etc, they aren't killing the Jedi. They're killing individuals. The Sith are individuals. The Jedi, conversely are an Order, a group, a community. Thus it is Vader, by attacking the Jedi temple, killing off the younglings (and thus the next generation of Jedi), and preventing more Jedi from being brought up, is the one who actually kills of the Jedi.

Palpatine lied about being unarmed
In Revenge of the Sith, when Mace and several other Jedi came up to his office to arrest him, he had his lightsaber pop out of some kind of springloaded sleave holster and went on the attack. It would hardly be a stretch of the imagination for him to still use that lightsaber and its rig, since he would be able to defend himself if a would-be assassin defeated his elite bodyguards (Vader can't be at his side all the time, you know). Why he didn't whip it out and use it is the real puzzler though...
  • Why would he? Vader was there and Luke fighting Vader was key to the "turn him to the Dark Side" plan. When Vader grabbed him he didn't really have time to grab his saber and it wouldn't have done much good anyway.
  • He might not even have bothered to use his saber anymore since he hadn't had to duel anyone for over twenty years. He seems to prefer to rely on Force powers instead of swordfighting if he can, like when he fought Yoda and started tearing down parts of the arena and throwing them at him. His lightning is more than enough to defend himself.
  • Agreed. He may or may not have had it on him; if not, he probably had it stored away and might have been able to Force-summon it. In any case, it doesn't really matter, as it's been implied that the Sith don't really need lightsabers: they just use them to mock the Jedi. His Force capabilities as, you know, the most powerful Sith in history would have been more than sufficient to take Luke apart piece by piece. As we of course eventually saw, albeit after the moron threw away his weapon in a largely pointless display of pacifism. In an action movie.

Vader threw the fight with Luke because he couldn't bring himself to kill his own son
The only time you see Vader really try to kill Luke is in A New Hope during the Trench Run, and he doesn't even know who Luke is at that point. When the Emperor tells him that "I have no doubt this boy is the offspring of Anakin Skywalker." Vader's first thought is how to turn Luke, so that they could overthrow the Emperor and end the war, ruling the galaxy as Father and Son. Him fighting Luke at Cloud City was a test, to see what his son's strengths were, and to try and sway him to Vader's side. Cutting off Luke's hand was an accident, which is why Vader stops attacking him at this point in the duel and instead reveals the truth, hoping to finally sway Luke to join him in overthrowing the Emperor.

Come Return of the Jedi, Vader is reluctant to bring Luke to the Emperor, but does so mostly out of hope that Luke will join him. His comment "It is pointless to resist" is him telling Luke to give in to his hatred of the Emperor, so that they can kill him and become the new rulers. When Luke makes a move to kill Palpatine, Vader steps in to stop Luke from turning to the Dark Side because he knows that Luke, having been swayed by Palpatine, will merely replace Palpaine rather than join with Vader. Notice that never once does Vader even come close to killing Luke, and Luke even manages to get the upper hand a few times (Force Kicking Vader down the stairs). When Luke hides in the shadows, Vader once again tries to talk him into joining him in striking down Palpatine ("Give yourself to the dark side. It is the only way you can save your friends.") His talk of turning Leia to the Dark Side is a furtherance of his goal of having the Skywalker family united and ruling a peaceful galaxy. When Luke attacks him this time, he cannot fight back without hurting/killing Luke, which leads to him losing a hand and almost dying at Luke's hand. If you look closely when Vader is lying on the catwalk, you can see him moving his hand as if to say, "Calm down, control yourself," to Luke, who is still wanting to kill him at that moment. He is trying to calm his Luke because killing Vader would leave Luke to be trained by Palpatine i.e. not part of the Vader Master Plan. In the end, he turns back to the Light Side and kills Palpatine once he realizes that this is a replay of the moment that he turned to the Dark Side: a Jedi is about to be killed by Palpatine right in front of him, and he has to make a decision who he will side with. This time, he chooses to reject Palpatine in order to save his son, and dies for it.
  • I don't believe Vader taking Luke's hand was an accident. You must remember that limbs are easily replaced in this universe (comparable to fixing a broken arm). Luke was not going to stop fighting until he died or was disarmed. At least two times, Vader basically stopped fighting to tell Luke to give up and that he's been beaten, only to piss off Luke more to keep fighting. Couple that with the hit that Luke scored on him (shoulder, I believe), Luke was more powerful and determined than Vader thought. Taking his weapon (and his hand) was the only way to stop the fighting that would end up with one of them dead so that Vader can try to convince Luke to join up.
    • Also, Vader wants Luke to join the Dark Side which you need frustration, anger, and other negative emotions to do. What pisses someone off? Cutting off their good hand is certainly one way. Plus if Luke had simply fainted from the pain and shock. Vader could hold him prisoner or at least take Luke with him so he could get him to turn in a environment that more suits Vader's needs.

Ben and Yoda lied to Luke specifically so he could kill Vader.
While Yoda tells Luke that they lied because they didn't think he could stand the truth, he was still lying. When he and Ben told Luke that Anakin was utterly lost to the Dark Side, they were lying. They knew that Vader might still have some spark of good left in him, but they didn't want that spark revived. Why? Because they didn't want Anakin redeemed.

After years of brooding over their failure and mourning their dead friends, Ben and Yoda wanted Vader punished for his crimes. They wanted him dead and rotting in Sith Hell, not redeemed by the Light Side and getting into Jedi Heaven. So, they lied to Luke so that he'd feel righteous anger (though not Dark Side anger) towards his father's supposed murderer, then go off and cut the armored buzzard down without a second thought. That's also why they didn't want him to try to save his friends: more programming for their cause and more reasons to hate Vader's guts.

Fortunately for everyone, Luke saw the truth and took the right path, resulting in Anakin's redemption, Palpatine's death and freedom for the galaxy.
  • In a less callous judgment of them, they probably did a risk/reward analysis and decided that even if Anakin did supposedly "have a spark of goodness left in him", Vader betrayed their order, slaughtered children, helped enslave much of the galaxy, and served as Palpatine's attack dog for nearly two decades, so that spark would be extremely difficult to bring out. Luke was too valuable to risk doing what they thought was likely a pipe-dream.
  • The problem with that is that all of that stuff is extremely contrary to the Jedi's teachings. Jedi don't seek revenge, they don't believe in using anger (even righteous anger) and they don't believe in killing where it can possibly be avoided. They would rather see a fellow Jedi redeemed than dead any day, especially considering they were almost extinct at the time. They probably just thought Vader was too far gone to try, since Obi-Wan already tried to bring him back and he failed.

The second Death Star was built faster than the first one because of spare parts.
The original Death Star was the first, so most of its elements had to be specifically created. While doing that, the Empire decided to produce spare parts as well, just in case. When the Death Star was destroyed, the Empire built the shield generator on Endor (which took longer than actually building the Death Star II) and then built the second Death Star using spare parts.
  • Or, it's just a simple case of a copy being easier to make than the original. It took decades of research, planning, fundraising, politics, testing & re-testing, and the inevitable "back to the drawing board" moments to get Death Star I built. For Death Star II, they already knew how to put one together; they just needed to fix the exhaust port.
  • The Empire already had the know-how to build a Death Star and the resources. Their government was more consolidated by 4 ABY than it was in 19 BBY, so they were able to order the project built and compel their shipyards to make it. (Command economies are generally good at large-scale industrial production, if not much else.)
  • This actually crosses into the realms of Fridge Horror when you think about it too much. If we reasonably conclude the Empire had spare parts to assemble a second Death Star battle station so quickly, one must then ask why they had spare parts. The solution is simple: They were planning to build more Death Stars! And this makes a bit of sense, too. For however mighty the Death Star was, it simply could not be everywhere in the galaxy at once, and in a situation where tons of planets have become active hotbeds of resistance, you can't wait around for it to travel to each rebelling planet individually. So what do you do? Create an entire FLEET of Death Stars!
  • Here's one more theory. There were members of the Imperial Senate that were sympathetic to the Rebels and they purposely held up construction of the first Death Star. Remember that the Senate was dissolved by Palpatine only four year earlier during A New Hope.

The Ewoks will eventually take over the galaxy.
The little Badass Adorable teddies can wipe out an entire army of apparently highly trained super soldiers, who have high tech weapons. The Ewoks used nothing but primitive sticks and stones. Surely the dead stormtroopers must have left much of their technology behind after their defeat. Just imagine once the Ewoks get the hang of using that technology.
  • It will be a long time before that happens. Most likely, it would simply lead to a case of Low Culture, High Tech. There would be no way the Ewoks would have the knowledge to use it to its full potential- or at least, not without outside help from the rest of the galaxy's inhabitants.

Leia's memories of her mother are visions from the Force.
In The Empire Strikes Back, Yoda told Luke that, through the Force, Jedi could see visions of the past, as well as the future. A young Leia, being strong in the Force, saw visions of Padme, her birth mother. However, Leia, not knowing about her true heritage, didn't realize just what she was really seeing. So, she interpreted them as being actual, if fragmented, memories of her mother. It's possible Luke had similar visions, but he responded by just putting them out of his mind, since he apparently knew next to nothing about his real mother and had no true frame of reference.
  • Jedi don't seem to be able to tell what visions they'll get. Sometimes if they meditate hard they'll have one, but sometimes they're unbidden (like Anakin's dreams about his mother or Padme dying, or Luke's of his friends being held captive). So Leia might have had some about her mother, but Luke never did for whatever reason, even though neither of them ever knew her.

Darth Sidious saw Vader's betrayal coming yet not as soon as it did.
Darth Sidious's reaction when being picked up by Darth Vader was like he was expecting Vader's betrayal yet was not done killing Luke yet. He most likely thought that he had enough time to kill Luke and truely turn Vader to The Dark Side. He saw Vader's hesitance to kill Luke during his Holo message and realized Vader still had good in him so when Luke refused to turn to The Dark Side he decided to finish Vader's turn to darkness by killing Luke and inciting Vader to vengance. What he did not expect was that he took too much time in killing Luke that Anakin would spring into action to stop him during the killing not after. Darth Sidious's fall wasn't an EvilCannotComprehendGood it was a DrunkOnTheDarkSide moment which as all such moments do took too long and ended ruining his plan.

Yoda didn't fancy Luke's chances much.
His training was clearly incomplete. Yet Luke will, according to Yoda, become a Jedi if he confronts Vader. Essentially what Yoda was implying was basically "if you manage to confront Vader and survive the experience/aren't turned to the Dark Side, you might just be good enough to be a Jedi after all." Except he doesn't quite put it like that, lest Luke be discouraged.
  • Alternatively, what makes a Jedi a Jedi? Standing up to a Sith Lord, and not being turning (regardless of whether you live or die) may be enough to make the grade.

Luke and Leia being siblings was a last-minute addition by Lucas.
Though Lucas may claim that he planned it all out, that would make the kiss between the two and the semi-flirtation really squicky(or hot), making us question Lucas' tastes. Originally, Lucas wanted a Love Triangle between Luke, Han and Leia. However he had to resolve it with Han and Leia pairing up, considering how popular the pairing was. And as we all know, Lucas is known for two things: Shocking family revelations and piss-poor romance stories. Leia being Luke's sister combined them both. Lucas thought we'd just forget the original Love Triangle angle, but even before the internet people are going to jump to conclusions.
  • Agreed. This is part of a larger issue with the Star Wars series, in that there have been several films made by George Lucas over many years, and the films contain contradictory information. Those contradictions can be explained easily by the fact that Lucas kept adjusting his fictional universe as he got new ideas, as any creative mind would.
    • This also explains why Obi-Wan told Luke that Vader killed Luke's father. It's because, at that point in the production of the story, that was what was to have happened. George Lucas made up the rest later.
    • Also notice that there is absolutely no evidence of midi-chlorians in the original trilogy. Instead, the Force was basically just magic in space. Later it was someone's idea to come up with a more "realistic" explanation for the Force, so that's the answer they came up with. If midi-chlorians existed in the Galaxy Far, Far Away, there would have been knowledge of them at least among the Force users Obi-Wan, Vader, Palpatine, and Yoda, yet none of them mention it ever.
    • C-3PO and R2D2 were present in the prequel trilogy, yet no mention of it was ever made in the original trilogy. Conveniently explained by C-3PO's mind being wiped, but neither Obi-Wan nor Vader remember the droids. And young Anakin supposedly build C-3PO himself!
