I thought about putting this stuff in one of the other threads, but oh what the hell, it's interesting enough to deserve it's own thread and actually answers important questions.
And here is a list of mysteries which have still to be unanswered:
Mysteries concerning Sora (Roxas), Riku and Kairi
Q1: Why do Roxas and Ventus look alike?
A: Because inside Sora, which is Roxas’ body, is Ventus’ heart.
As was shown in the opening to BbS and the ending to Last Episode, Sora and Ventus’ heart are linked (P.646). And so Roxas, who is a part of Sora, was affected by that and looks just like Ventus.
[picture: Little Sora and Ventus’ heart]
Ven: “Can I become one with your heart again?”
When he was born into the world, he linked with Ventus filling his fractured heart. Many years later, when Ventus was on the verge of disappearing after his fight with Vanitas, Sora took him into his own heart.
Q2: Why did Roxas faint in Castle Oblivion on Day 297?
A: Because he had gotten to close to both Sora and Ventus, his “real self”.
Before Day 297 in Days Sora had been to Castle Oblivion, as well as the fact that Ventus is asleep somewhere in the Room of Awakening. Both Sora and Ventus can be called Roxas’ “real selves”, and when he felt their presence it made him faint.
[picture: Axel and Roxas]
When Roxas went to Castle Oblivion the memories of his “real selves” made him confused.

Q3: Is it possible that Roxas has a heart?
A: It is thought that it could be Ventus’ heart.
In KHII FM there were clues to him having a heart, and in Days we saw Roxas crying--proof that he could have a heart. As was said in Q1, he has taken a lot of himself from Ventus. But perhaps when Sora and Roxas were separated, Ventus’ heart stayed in Roxas?
[picture: Roxas crying]
On Day 357, Roxas cries after losing his friend Xion.
[picture: Little Sora and Ventus’ heart]
Sora links with Ventus to help heal him.
Q4: Why can Roxas dual-wield?
A: Because he can use both Sora’s and Ventus’ keyblades.
Sora can wield two keyblades at once because he has Ventus’ as well as his own. As Roxas is a part of Sora, he also can use two. In Days Roxas awakened his ability to dual wield after fighting Xion. In KHII once Sora absorbs him, he can also dual-wield.
[picture: Roxas and Riku fighting]
Roxas awakens his ability to dual-wield with his will to not forget Xion who also wielded a keyblade.
Q5: Why was Riku chosen as the original wielder of the keyblade?
A: Because he was chosen by Terra to inherit.
To use a keyblade you must have been chosen to inherit as well as been chosen by the keyblade itself. In BbS you could see that Terra performed the ceremony with Riku, and that is why Riku was able to take the keyblade that Sora used.
[picture: Little Riku and Terra]
Terra looks at Riku as he performs the inheritance ceremony.
[picture: Little Riku looks at a door with a keyhole.]
Because he has been chosen to inherit, Riku can see the keyholes of the world.
Q6: Why did Kairi end up with Sora and Riku?
A: It has to do with Aqua’s “magic”.
Nine years before KH, Kairi was thrust into the outside world, and found herself on Sora and Riku’s world. Ansem Seeker of Darkness thought that she had been able to search for a keyblade wielder, but what actually saved her was the magic spell Aqua had put on her.
[picture: Little Kairi]
Aqua: “Someday your light will lead you to a light that will protect you from the darkness.”
The magic Aqua puts on Kairi saves her once year later.
[picture: Ansem Report]
Ansem Seeker of Darkness felt a special power within Kairi and tried to use her to find the keyblade.
Q7: Why can Kairi use a keyblade?
A: Because she was touched by Aqua’s keyblade.
The keyblade inheritance ceremony is performed with a keyblade master touches someone using a keyblade. When Kairi was running away from the Unversed in BbS she grabbed Aqua’s keyblade, which performed the ceremony. That is why she is able to use a keyblade in KHII to help Sora.

The keyblade Kairi uses is the same with Aqua receives after talking to Kairi: Destiny Place.
Mysteries concerning “Xehanort” and Organization XIII
Q8: Who is Apprentice Xehanort really?
A: Master Xehanort commandeering Terra’s body
Master Xehanort wishes to bring back the Keyblade War and see what happens afterward with his own eyes, but once he found a way to accomplish this he was already an old man with only a few years left to him. Wishing to become young again, he finds Terra, and defeats him with darkness so he can take his body. That is the Xehanort that Ansem the Wise picks up, and makes his number one apprentice.
[picture: Terranort and Aqua]
Master Xehanort has taken over Terra’s body, but Aqua tries to get Terra’s heart and self to return to it.
[picture: Ansem picking up Xehanort]
Afterwards he loses his memory and is picked up by Ansem the Wise.
[picture: Apprentice Xehanort]
Calling himself Xehanort, he becomes Ansem the Wise’s apprentice and goes into the study of darkness.
[pictures: Ansem Seeker of Darkness, Xemnas]
Xehanort’s Heartless calls himself Ansem Seeker of Darkness, and his Nobody calls himself Xemnas.
Q9: Where did the Organization’s coat and mark come from?
A: Xemnas remembering his human years.
One year after BbS, Xehanort as well as five other apprentices toss aside their hearts. Then the Nobody Xemnas was born, and the Organization which he creates take a lot of things from his memories as a human. But as Xemnas had two people who he was, Terra and Master Xehanort, he takes from both of their memories.
[picture: Master Xehanort in dark coat]
The coat used by the Organization was something that Master Xehanort originally wore.
[pictures: Terra’s mark, Nobody’s mark]
The Nobody mark used by the Organization is a similar shape to the mark Terra used.
[pictures: Roxas receiving his name, Vanitas and the X-Blade]
Xemnas gives Organization members names with an X in them. This has something to do with Master Xehanort’s interest in the X-Blade.
Q9: What is the origin of Castle Oblivion?
A: It is the transformed version of Land of Departure after it was sealed.
Castle Oblivion's original form was Land of Departure, where they were in training. It is a special place between the realms of darkness and light, and has been protected for generations so that it is not used for evil. A device was set in place just in case of such an event, and after Master Eraqus was killed and Aqua closed the keyhole of the world, it put this device in action. It turned it into a castle which would draw anyone who goes there into oblivion.
[picture: Aqua in front of Castle Oblivion]
Castle Oblivion, which was born from Aqua sealing away Land of Departure. Afterwards the Organization, under Xemnas’ orders use this place for research.
Q11: Why is Aqua’s armor in The Chamber of Repose?
A: Because Aqua tried to save Terra.
When she tried to retrieve Terra’s heart from Terra-Xehanort, they both fell into the realm of darkness, and she gave him both her armor and keyblade which allowed him to escape. Because of this when Ansem the Wise picked up Xehanort, he still had the armor and keyblade, which Xemnas then put in The Chamber of Repose.
[picture: Aqua and Terranort in darkness]
Aqua gives up herself in order to save Terra.
[picture: Xemnas in The Chamber of Repose]
Xemnas creates The Chamber of Repose, and puts Aqua’s armor there which he calls “friend”.
Q12: Why is Xemnas searching for The Chamber of Awakening?
A: To find Ventus.
The Chamber of Awakening is the room where Aqua leaves Ventus sleeping in Last Episode, and is a part of Castle Oblivion. As you can see from Xemnas calling Aqua’s armor “friend”, it seems Xemnas has Terra’s memories and so is searching for Ventus, and is making the other Organization members look for The Chamber of Awakening.
[picture: Aqua with Ventus]

[picture: Xemnas and Saix]
The only one who can solve the mysteries of Castle Oblivion is Aqua, so the Organization was never able to find it.
Q13: What is the true form of Lingering Sentiment?
A: After Terra lost his body, his thoughts gathered into his armor.
At the end of Terra’s scenario, Master Xehanort had commandeered his body, so his thoughts took control of his armor. Afterward, the armor stayed in the keyblade graveyard, until KHII FM where “Lingering Sentiment” went against Sora. Because he saw that it was not his chosen one Riku using a keyblade, but Sora, he grew suspicious and thought he had something to do with Master Xehanort and attacked him.
[picture: LS and Sora]
After fighting him, LS says this because he feels Ventus inside of Sora.
Q14: Did something happen in Xigbar’s past?
A: He was Master Xehanort's accomplice.
The number two member in the Organization Xigbar conspired with Master Xehanort when he was a human named Braig. Because of this, he knows more about Xemnas, who is the Nobody of Xehanort, than anyone else. That is why he often says strange things, and can speak up against Xemnas.
[picture: Braig and Master Xehanort}
Braig was involved with Xehanort's plans, but as you can see they have some sort unknown promise between them.
-Where he got his eye patch and scar-
As Master Xehanort was trying to get Terra’s body as a vessel for himself, Braig tried to lure Terra into the darkness by fighting him. But the power of darkness that Terra released was stronger than he would have imagined, and he ended up losing his right eye and getting a wound along his cheek. Afterwards Braig’s ears become sharper, and his brown eyes change to gold. This is because he was influenced by Xehanort who he was working with.
-Things Xigbar has said in the past-
“Why are you always looking at me like that?”
(Days, Day 353: When he sees Xion as Ventus.)
“Oh yeah, he looked at me like that too!”
(KHII: Facing off against Sora in Hollow Bastion.)
At the end of Ventus and Aqua’s scenarios, they went against him in the Keyblade Graveyard, and Ventus glared at him while frozen. This is Xigbar remembering that scene.
“How many years ago was that.... when those guys with the key shaped swords appeared here and fought. After they disappeared, a man who lost his memories fell.”
(KHII FM Xigbar talked with Zexion about Xemnas’ secrets.)
This is pointing to when Aqua fought Terra-Xehanort in Last Episode.
“So you are one who has been chosen by the keyblade. Though you’re nothing compared to the ones I’ve seen before.”
(KHII: Facing against Sora.)
“The ones I’ve seen before” is referring to Terra and Aqua, who he has fought against before, as well as Ventus, Master Xehanort and Vanitas.
Q15: What sort of people were Organization members 3-8 as humans?
A: We know now that they had ordinary lives in Radiant Garden.
In BbS we’ve seen one part of Xigbar’s past, as well as members 3-8. 3-6 were apprentices under Ansem the Wise and did things like act as guardsmen, but Axel and Saix were just young boys who were friends.
[picture: Organization members and their original forms]
1-6 were the original members of the Organization, and during the time of BbS were Ansem the Wise’s apprentices.
[picture: Axel and Saix]
Axel and Saix were old friends, as we can see from their conversation.
[picture: Lea and Isa]
Lea and Isa were friends. It seems during BbS they wanted to get into the castle of Ansem the Wise.
[picture: Zexion and Vexen]
Is the reason Zexion speaks so politely to Vexen because he was under Vexen's care when they were humans?
[picture: Dilan and Eleaus]
We can see that they were guardsmen of the castle in Radiant Garden.
Q16: What happened to Ansem the Wise?
A: He is wandering in the realm of darkness.
Ansem the Wise, who banished to the realm of nothingness by his six apprentices. In KHII, he wanted to release the Kingdom Hearts made from people’s hearts that the Nobodies of his apprentices had created. The machine that he used for that end exploded, taking him with it. It looked as though he disappeared, but we know from the secret event in BbS that he was sent into the realm of darkness.
Ansem used Sora and Riku to get his revenge against his apprentices.
[picture: Ansem and Mickey with machine]
Ansem tried to test the heart’s data form with his machine, but it didn’t go as planned and the machine went berserk.
[picture: The realm of darkness.]
Ansem the Wise was thrust into the realm of darkness, forgetting all of his memories except those concerning Sora.
Q17: What made Maleficent want to take over the world?
A: Because of what she learned from Master Xehanort.
In KH Maleficent tried to steal the hearts of the princesses of light by using Heartless soldiers. The reason she decided to do this was because Master Xehanort had told her “If you gather the hearts of the princesses you will be able to control the world.”
Q18: Why was Pete put in prison?
A: It was a punishment for stepping on the hearts of others.
In KHII Pete tells us he was saved from prison by Maleficent. The reason he was put there was because during the Dream Festival he said things that showed he cared little for the hearts of others.
Q19: Why did Merlin have Winnie the Pooh’s book?
A: Terra picked it up and gave it to him.
In KH he tells us that it’s not really his book, it had just been in his bag. In BbS we see that it had fallen there as if drawn to him, and Terra had picked it up and given it to him.
Q20: Why was Scrooge so interested in ice cream?
A: He’s always been interested in ice cream.
In Ventus’ scenario we find out that the ice cream machine that Huey and the boys were using was original Scrooges machine. As he has always been interesting in making ice cream, that is why he was so interested in it in KHII.
And here is a list of mysteries which have still to be unanswered:
(?) Did Apprentice Xehanort really lose his memories?
Master Xehanort commandeered Terra’s body, and became Ansem the Wise’s apprentice. According to Secret Ansem Report 1 From KHII, the young man asked to become a test subject for Ansem’s research so he could get his memories back, After that they began the study of darkness, but did he really lose his memories? And are those memories Terra’s or Master Xehanort’s?
[picture: Xehanort and Braig]
As seen here, Braig thought that his memory loss was nothing but an act.
(?) Where is Master Xehanort’s keyblade?
As was stated in Secret Ansem Report 13 in KHII, while studying darkness the young Xehanort opened the door to the heart of Radiant Garden. This would have been possible if he had a keyblade, but according to the Ansem Reports 4-8 in KH, he did not yet know about the keyblade at the time. In Last Episode Master Xehanort used his keyblade up until going to the world of darkness, but what happened to it after that...?
[picture: Terranort sticking himself in the chest with a keyblade]
In Last Episode Terra-Xehanort stabbed himself in the chest with his keyblade, but afterward that keyblade has disappeared.
(?) What are the “seeds” that Xehanort has planted?
In the secret event, Master Xehanort tells Terra that he has already laid many plans, and that the seeds have been sown. Telling Braig and Maleficent about the “Kingdom Hearts” was one part of his plans, but what other plans have Braig and Master Xehanort laid? What other measures have been taken?
[picture: Master Xehanort and Braig]
If pushing Maleficent into trying to take over the world was one of his “seeds”, then what things has he been saying to Braig?
(?) What are the details of Ansem’s apprentices fall into darkness?
Most of what had happened with Ansem’s apprentices before their fall into darkness is unknown, aside from what was touched upon in Secret Ansem Reports. And the mystery of “the plan that was decided on after Axel and Saix entered the Organization” that was talked about in the Secret Reports in Days still remains. According to Nomura there is still much about the Organization’s humans that has yet to be said.
[picture: Dilan and Eleaus guarding the castle door]
During BbS the apprentices seem like kind people, so was it Xehanort’s influence that led them into the darkness?
(?) What happened to his heart and memories after separation?
One year after BbS, Apprentice Xehanort was separated into his Heartless (Ansem Seeker of Darkness) and his Nobody (Xemnas). The former took actions that were more like Master Xehanort, while the latter has said things that seem more like Terra, so how were Terra and Master Xehanort’s hearts and wills separated, and what sort of influences do they have over each?
[picture: Organization member (don’t remember who said this, Xigbar?)]
It is also a mystery that he would know about the room where Ventus sleeps, which should only be known to Aqua.
(?) Did they meet in the realm of darkness?
In the secret event we see Aqua and Ansem the Wise talking in the realm of darkness after the events of KHII. Over one year before Mickey traveled to the realm of darkness to search for the keyblade, but during that time did they really not see each other? If they did, then how does that relate to the story afterward?
[picture: Aqua in the realm of darkness]
Aqua wanders through the realm of darkness, holding Eraqus’ keyblade.
