Birth by Sleep Completely Insane Theory

This was just completely random so don't expect a 100% theory anyway:
During the 2008 trailer I noticed that Xehanort said something about erasing his mistake and I think that his mistake would be Ven instead of the Dark Solider. Why?

• Xehanort has a apprentice athe "Dark Soldier"
• Both of them belived in the darkness
• Sometime in the story DS dies
• Xehanort tries to find a new apprentice so he turns to Ven
• Soon Ven was engulfed in darkness and became very powerful
• Xehanort started to realize his mistake
• Terra wanted to help his friend so he goes to Xehanort
• Xehanort offers him a way to defeat Ven by letting Terra go into darkness instead
• Terra soon accepts and becomes the DS

Here are some weird facts:

• DS's keyblade look like Terra's
• When Xehanort talks about his mistake the camara zooms at Ven

I know this theory has many loopholes but it is possible.

 

but if that is true... how can both Ven and Terra be fighting Master Xehanort and Dark Soldier in the FM+ secret ending??

 

Willi has a point. The secret ending happens at the end of the game so DS lives until the end

 

Like I said this is just a theory I know it has many flaws but it's just my opinion.

Which trailer said that the secret ending appears at the end?
I just can't remember.

 

When it first came out, Nomura said it was the beginning of the game and that TVA separate after the battle. But people have been saying he changed it to the end, but I haven't seen that interview myself.

 

I don't think Nomura changed it to the end because based on the trailers it seemed that TVA already separated.
But still the story is foggy so right now everything is just speculation.

 

Nomura: The secret ending [from KH2: FM+] is actually a scene from Birth By Sleep, therefore the title of the game is also the same. However, because it is difficult to express such a violent battle as playable content, the secret ending [from KH2: FM+] is an image (scene?) of the end.(

It was near the end

He seemed more interested in Terra

Where is there evidenece to back this up?
Terra looked to be the one using darkness

They are two seperate people

 

i think it may be near the nd but certainly not the end of it.
nomura always like to surprise us.

i think KH is just one surprise after another (another surprise is that someone hasnt died of shock yet)(then again youd have to be a real fan to get enough shock from the story for that to happen :D)

 

It isn't as insane as it is played out. you aren't the first person to come up with this theory. many people have come to that and other conclusions.

A few things i'd like to point out;
-Ven has no heart which means darkness has nothing to infect, which makes it impossible for him to turn into DS
-Terra has already turned to the power of darkness, Master Xehanort's trying to stop terra from plunging into darkness.
-DS's keyblade actually looks like a more keyblade like version of the soul eater.

Heres my final point and i'd like everyone to see this
Master Xehanort hates the darkness. He would not help someone turn to darkness, he would not turn to darkness and he most certainly wouldn't leave someone turn to darkness if they had a keyblade as he has explained.

I say again, HE HATES THE DARKNESS WITH A PASSION IN IS NEITHER WITH THE DARKNESS OR ASSOCIATED WITH IT OK?
