The 2017 we see in episode 1 in the scenes with Sento and Banjo had a skywall, a Smash and their secret hideout from during the show.

The 2017 we see when Another Build is created (and throughout all of episode 2) had none of that. It was just the standard world. So, we see two different versions of 2017 in these Zi-O episodes even though none of the characters comment on it directly since it's not really related to Zi-O's plot.

Build's epilogue scene in the "New World" was heavily implied to take place in 2017.

-2017 is the only date shown (through the Cross-Z RideWatch)
-New government cabinet announced on tv, and Japanese general elections were in 2017.
-They show a remake of the Sawa/Gentoku meeting from the beginning of Build.

So, they basically showed the Build World 2017 in episode 1 in order to make Build references with the skywall, Smash and their hideout, and then just had Sento and Banjo in the main world's 2017 for episode 2 since it works better for Zi-O's setup.

I'd guess they didn't attempt to explain how that works for several reasons, like Zi-O still establishing its basic premise and cast during these episodes too, so commenting on an unrelated alternate world set up (and that world being fused away) would just overcomplicate things.

Ooooh, right see that makes sense. Yeah no okay, I guess that just makes everything work. That also makes it alot more clearer how Sento and Ryuga could like continue existing in the main timeline.

I don’t understand a thing of what I watched...
Basically Episode 1 was the Skywall world from Build and Episode 2 was when the Skywall World fused with the Original world...

After their encounter in original 2017 Sento and Banjo don’t remember a thing about who they are and they lost their powers...

We see them in 2018 and they regain their memories after giving the Ridewatch... basically?

And Geiz says that Build is not back...so what does that mean? Sento and Ryuga permanently lost their powers? Do they remember who they are?

If someone can clarify....

It's not really a perfect loop. Sento and Banjo initially lose their memories and powers due to the Another Rider, but afterwards even with the Another Rider destroyed they're still lost for some other reason (which will be explained in the future according to 2.5), although the episode implies that it's related to Zi-O and it's outright stated by Geiz to be part of the timeline that leads to Oma Zi-O. Sogo believes they will become Riders again though and we do have a movie in a few of months with Build and Zi-O together again...

This is my face attempting to understand how all the time travel works in this show. It pretty much doesn't, so we're going with a "No Rules" scenario. (Or rather, three rules, one of which is 'Don't think about it to hard'.)

And, considering that rule, this wasn't a bad episode. All the characters get to show off a little personality, Sento and Ryuga's cameos are neat, and I will never be sick of "Let's get Yanikiku Tonight" references. And they have me hooked for next episode with the promise of the Only Winner. I'm definitely EXCITE.

So Zi-O is damned if he does and damned if he doesn't. Letting the time jackers fuck with the past and replace riders with another riders is no good but just Zi-O being there and obtaining the rider powers also erases the original timelines. Damn. Sougo is asking a lot from Geiz, Tsukuyomi and the audience to believe in him and his ability to do the right thing in the end.

I'm interested in where this goes. It's kinda funny that the anniversary season is "destroying" every season before it haha.

Oh and why is our boy Emu always so pissed off? lol

I am sorrow. I am disappointment.
Zi-O sucks 'cause it's written by incompetent.
Episode 2.5 is a pathetic excuse
to deliver a wild card to plot hole abuse.
That will be a record for me
to drop a KR show before episode three.

Correction: It wasn't Zi-O & Geiz "beating" Another Build in 2018 that jogged their memories back, it was Zi-O & Geiz beating Another Build back in 2017. It's just a timelapse thing. Around that time, simultaneously, was when Another Build was defeated.

Umm, what??? Just cuz it doesn't show the Skywall consistently doesn't mean it's not there. Build's Series in of itself had multiple instances where the Skywall wasn't shown at all, yet we always knew it was there obviously. This claim is moot.

-Not enough proof. The RideWatches simply display the year that the Rider's show started.
-Fictional universe, bud. Their elections don't have to coincide w/ ours.
-This....is actually a pretty good point. But it's your ONLY good point, so still, this statement is still pretty shoddy of proof beyond a reasonable doubt.

No, the Build World we see in Zi-O's going back to 2017 is the original world, where the Skywall existed. 2017 is when that world still existed, therefore, it's available to go back to. After all, if they really did go to the New World, where the Skywall & Evolt never happened, then why would Sento & Ryuga have their powers when there's no threat to fight, and why would Sento still be a thing & not be Takumi Katsuragi & Sato Taro instead?

-Delete this

I mean, they made it a point to show the Sky Wall in the first place. That last scene with Banjou waving to the Time Mazine's would've featured the Sky Wall if this was the Sky Wall World.


Because the main timeline has a Takumi Katsuragi and Sato Taro, it doesn't have a Kiryu Sento. They point this out in Build's ending that because Sento is neither Katsuragi or Sato he continues to exist in the new main timeline, same with Evolt DNA Banjou.

In episode 1 of Zi-O they also show two different 2017's, the Skywall one (That Geiz knocked Zi-O into, as in forced into another timeline) and the main one where Another Build gets made.

The only way for Sento and Banjou to actually be in the main timeline while also being able to forget everything that happened is that the merge brought them back to 2017. If this was the Sky Wall World, Then that means that they never would've gotten to the main timeline in the first place.
