I do have a part of the CoM retrospective addressing Sora forgetting things by world, but had forgotten about that by the time we get to KH2! I'll try to add it back in when I get back.
I agree that Namine just left Riku in deliberately, but even if CoM had played out "as it appeared," (with no twist), I think we can presume that Replku being in front of Sora would have kept him in Sora's mind. After all, the same appears to happen to Donald and Goofy, too! That's one of CoM's brilliant points. The deception is so thorough that you can't help but forget parts of it when you try to look back on the game!
@Shard: Tell me about it. Explaining the Chain of Memories one revelation at a time is one of the most daunting parts of this section of the retrospective. I kept tripping over myself on previous edits and should probably make sure it isn't still confusing in the current draft!
Status Update: The internet is out at my apartment. Someone's doing some work but it doesn't seem to be done yet, and I can't say for sure when it will be done. They say it might be done tonight. If that happens early enough, great, I'll still be able to get up the CoM entry for tonight. If it's not (even if it's done today but just particularly late), the Tuesday CoM entry may be delayed or skipped. I don't imagine the delay will last until the Thursday TAY post.
Ideally, I may put the entry up on Wednesday, but like the skipped FFIV-I post a few weeks ago, it might prove easier to just skip a day as tomorrow is going to be a mess, internet or no. It's going to depend on circumstance. I'll try to keep you all informed!
