Kingdom Hearts II Sora's lost memories

hi guys
i was thinking about sora's lost memories about castle oblivion.
in kh 3 will sora remember about this? because i saw a cutscene(Kh 2 final mix) where sora says''i didn't thanked namine'' and riku responds him that he can still do it.
he's starting to remember his memories on castle oblivion?
another thing why sora doesn't recognize marluxia absent silhouette?i mean a sign in his heart(like when he first arrived on hollow bastion)?,his mind can't remember but his heart does,so why?

 

Well it's possible Roxas was remembering since it was Roxas' fault that Sora cried when he left Twilight Town. Also it's thought that when Roxas and Sora became one at the end of the game that he did remember everything, he just didn't make a big deal about it. Another theory is that a future game will have him remember everything.

 

If you remeber from khCoM Sora explained to Namine that even though he'd forget her that the memories themselves will still be with him so he can never truely forget.... though I do think the "Thank Namine" thing was probably a refrence to the entry in Jimminy's jornal

 

I believe he's referring to the excerpt from Jiminy's Journal. "Thank Namine"
That, or he could be experiencing his memories coming back from being back with Roxas.

 

Sora can't be remembering since namine rearranged those memories somewhere else in his heart meaning she has to undo that so he can remember again.

I would say its this because he just found out who namine is when Roxas and her went back into Sora and Kairi. So hearing her name reminds him of the Journal entry it said when first waking up.

 

I think the only way Sora can remember what happened in Oblivion is that he gets his chain of memories back the way they were when Namine first changed them.

 

Sora will meet Naminé again in KH3D, bbut probably he won't remember about Caslte Oblivion because....

I just think that KH:CoM's story is a story that is better let unknown but our heroes. After all, Sora had the choice: Keep with memories of Castle Oblivion and the False Memories, or forget about the CO memories and restore his memories -without Castle Oblivion.

And maybe he go back to CO, but don't remember about it, just "this is a new world but I feel like I already was here before... the end, go rescue Ven and done".
