I'd just have an idea about Lea in Kingdom Hearts 3 trailer.
Lea was fighting with Kairi to Heartless when the Heartless start wars front of them after he protect Kairi from huge stronger Heartless, but he was flew away from this place when he dodged it as look around at someone did hit it "Who are you! "
SomeNobobodie was stand front of him behind and spoke in deep familiar voice "I thought you forget about my voice to you, Number VIII."
He frozen in shocked it as knew that voice was his ex leader as he look around at Xemmas look calm downed with glared it, but he with someone he don't know yet it "Xemnas... What are you doing here? Or Kill me?"
He look at him as silent tone but he let someone start fight with Lea don't recognize that keyblade but he feel he seen this keyblade before "Number VIII... Why could you join this boy Sora and his other for this?"
Lea glared it as kept fighting with someone hold keyblade "Because Roxas is my friend! But, I don't abandoned my friend Isa I left it!"
He stopped someone froze after disappeared into dark portal front of Lea confused for not understand what he talk about something "I see. That's why you feel different when you were Nobodies after you betrayed us for care Roxas, but because he used you for his tool to making you feel hurt he wanted it. you'd never knew what you feel it because itself chosen you are Darkness of human where you wearing your coat as you are one of us."
Lea shock in widen as not believe what he said it "... Who are you?"
The blue haired long and look at them before he was stand front of Xemnas behind "Because we take you back to Organization where you belonged it, Lea."
Lea feel like his heart ripped in piece but shouted it "No, I'm not going back to where I belo-" He gasped in surpise when Xemnas use his power to darkness circle front of Lea stand after bean light hitting into his chest
Xemnas starting at him "It's for getting sleep where you belong... That is time for sleep."
The Princess moan in pains when she was hurt a bit from Heartless attacked it but she saw Lea was hitting in bean light from Xemnas "Axel!" She runs to save his life after she hitting Xemnas's head behind but she missed it when Xemnas disappeared with Isa away from Lea fall down on the ground
Lea lost his conscious on the ground after she put him on the rock behind and shouted it "Axel! please wake up! "
Something with wrong happened to Lea she felt it about different more when she look around Heartless flew around to then as she gasp in shock and jump to trying protect Lea "Axel!"
She look around at her friend Sora yelled in her name was too late into the darkness last time
When she was with Lea on unknown place before she woked up and worried about Lea don't wake up yet, but someone just come out of dark portal front of herself "Who are you!"
The blue haired ignored her as walk to him "Lea... Let me take you to home back." He put his arms around on his neck and carries Lea in his arms
Kairi shock in widen and summons her keyblade point at him "Give Axel back to me! I don't let you take him away!"
Isa look down at herself as summons the dark portal front of Kairi stand on the ground after she gasped as she fall down into the darkness "Axel!" She saw Lea sleeping in his arms last time.
What's I thought it from the trailer of Kingdom Hearts 3 as about Lea is really the vessel of Xehanort? Or not?
