questions about movie war 2010 (and my theory)

not sure if this is in the correct place if not please move it thanks.

anyway, i have some questions to "world" in the movie. my theory:

"rider war world a": this is the same world that is in the decade episode 31. the world in the beginning movie where decade finish skyrider, super 1 and kabuto is the same world.

"rider war world b": this is the world natsumi and diend is in. it should be a different world, since decade and j is seen travelling to THIS world during their battle. the backdrop is also different from decade ep31, so in between the episode and the movie, natsumi must have travel to this world, with decade and kuuga in "rider war world a". and in the SAME world, natsumi's grandpa go to a roadside store to wait for RYUBEE (from double) and meet narutaki there.

does this mean "rider war world b" = "double world"? nazca also say he saw grandpa and ryubee talking together. this MAY be in the past. maybe natsumi hometown in decade episode 1 is also the "world of double" and this is the same world. decade is also not seen travelling from to the "world of double".

however, after the battle finish, decade travel back to another world (where natsumi is). so "rider world b" is not "double world" in this case. maybe decade travelin to "double world" is unseen.

is there someone who can clear my doubts? maybe "rider war world b" and "double world" is different but that does not explain why grandpa know ryubee. maybe this is a just a plothole the producer does not notice or choose to ignore.

the backdrop is also different from decade ep31, so in between the episode and the movie, natsumi must have travel to this world

Actually, Daiki says that Tsukasa was there (pointing to the backdrop), so it's strongly implied that they aren't in the world shown by the backdrop, somehow. Some material from before the movie's release mentioned the Rider War World revealing its true form, and I guess the new backdrop is a reference to that, but the movie didn't really mention anything about that directly.

About Double's World... It's not any of the 2 worlds initially shown in the Decade movie. The Riders had to go through a dimensional wall to meet up with Decade and Double in the 3rd part, and after the battle ended Tsukasa left with another wall, leaving Shotaro and Phillip behind, so the Double world is different from the ones shown in the Decade movie.

However, I guess Double's world might be Natsumi's world, which would explain how Eijiro and Ryubee met in the past. Considering how Ryubee gave Eijiro a memory that made him work for Dai-Shocker, he might have some Dai-Shocker connection, which would explain how he could have met Eijiro at least once in whatever alternate world the studio was (Eijiro seemingly was waiting for him when he met Narutaki in the beginning).

In your world a Decade destroys Skyrider, Super-1, Tendou, and fights some Riotroopers and J this may be the Rider War World or a different world, as Decade is now travelling worlds to find the remaining riders and destroy them, and Tendou, Shinji, Kenzaki and Onodera have presumably been travelling the worlds searching for allies. He later comes to what I'll assume is the World of W which I guess is also Natsumi's world, and I assume Ryubee and Ejiiro were old friends. I presume the scene where Kirihiko sees Ryubbe give Ejiiro the memory was the recent past, and specifically caused ejiiro to become Super Shinigami Hakase when his memory was triggered, I presume he had been using a different memory in all riders which meant he was only Shigami Hakase, which I guess Ryubee gave him prior to the series, and was destroyed in the battle in al riders. The world Tsukasa is in in the epilogue has a differen background so he could have crossed dimensions to another universe, the studio maybe being brought by Ejiiro and Natsumi.

ok lets only talk about the final world. we could say that the world that decade and j cross into and meetup with natsumi is natsumi hometown, or double's world, since the grandpa knows ryubee and they are in this world for the rest of the movie. however, if this is the case, why does decade need to go to another world in the final part after the battle? natsumi should be in the SAME world (double's). unless he just travel to another place in the SAME world (which could be the photo studio)?
