358/2 Days Days and Memories

In the events of Kingdom Hearts 358/2 days axel and other members go to castle oblivion. Chain of memories is happening at the same time as Days right? The only problem I see with that is that Riku interacts with Roxas even when the organization members are at castle oblivion. How is this possible? Because in Reverse/Rebirth Riku still knows nothing of Roxas or Soras memories. And at the end of Days Riku obviously knows about all of this and even before then when he defeats xion he knows. What is the timeline on these two games??

:)358/2 Days is my 2nd favorite kh game :)

 

Because by this time, Riku's already working with DiZ who had probably already explained everything about Nobodies and stuff.

 

He interacts after. A while after it's been established that all of the members there died except for Axel is when you see Riku

 

But wouldnt he still be in castle oblivion? Or is his story at a differnt time then soras?

oh ok but in "The man in black reflects" Aren't the organization members are still at castle oblivion?
