When W executes CycloneTrigger's Maximum Drive, he inserts the Cyclone Memory into the Trigger Magnum instead of the Trigger Memory.
It is unknown when, where or how the Time Police came into possession of the Diend K-Touch, or even if they built it (and possibly the Decade K-Touch) themselves.
Eve says that the Time Police will be protecting time from now on. However, it is unknown what took them so long; if they possess time travel, they should have been encountered long before, such as when Ryoutarou first became Den-O in 2007, especially as they considered what he and the Taros were doing to be illegal.
Somehow, when Urataros escapes from G Den-O, he has the DenGasher Rod Mode with him, despite Reiji having the Den-O Rider Pass. He should have had his natural Imagin weapon, the Uratarod. Either way, he doesn't use it and it's no where to be seen when Urataros next appears. It's not until everyone gets back on DenLiner that the DenGasher is used. The Uratarod only appears when Urataros is Kamen Rider Diend.
It is unknown why the Spider Imagin here is identical to the Spider Imagin from the series. Imagin bodies are formed from their contract holder's mind so it is unlikely two people would have th exact same mental image of the creature from the story.
Although the first transformation into NEW Den-O Strike Form and Kintaono is consistent with how Kotaro and Teddy worked together, in Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Battleship, possession by Deneb created NEW Den-O Vega Form, not a seperate weapon. It is unknown why it would be different for Deneb, although it may be that he is more compatible with Kotaro that the Taros.
Although the Time Terminal was previously shown to exist within the sands of time, here the Mantis Imagin appears to escape from it directly into the city. However, he may have exited the sands unseen or Den-O Sword Form stopped in while still in the Terminal in an area using the previously established hologram system
For some reason, the Dummy Memory has a female voice instead of the usual male one.
Unusually, Shijima's Dummy Memory did not speak its name when he transformed in the church, but did when he was later outside.
The close up of the Xtreme Memory after it saves Shotaro from the Energy Dopant shows the damage to it's left wing, but the damage switches to the right between shots as Phillip reappears.
As Shotaro and company walk down the street, Futo Tower in the background appears to be complete; even the blades are turning. However, the shots of Wakana show the tower surrounded by scaffolding with the blades immobile.
The close up of Jun's PDA that is supposed to be monitoring Wakana's energy levels reveals that the indicated 72% is actually a program being installed, as it reads "It is installing it..."
Phillip is apparently able to sense Shotaro fighting the Utopia Dopant, even though they are not connected by the Doubledriver belts.
Ryu seems surprised to see that Mick was the Smilodon Dopant, even though Phillip had looked up all information on the Dopant earlier and Ryubee even referred to it as Mick at the Museum.
Despite the Raito Sonozaki book supposedly containing all information on Phillip, the page headers visible as he reads are "Syriac Language and Literature", "Syrian Churches - Syringa", " Syrink - Szechenti" and "Taal, Mount - Tabasco"; Phillip appears to be reading an English dictionary.
Although Shotaro was meant to be reliving the day before, when he relived his cat impressions outside Futo Hall, he was facing a different direction.
Somehow Phillip new the term "super compatible person" without having heard it. Isaka had only used the phrase when speaking to Ryubee.
Phillip says that Accel is the only Kamen Rider left in the city, but he could still transform into W FangJoker at any time as it would not require use of Shotaro's injured body, only his consciousness.
Isaka is shown to insert the Weather Memory into the side of his head, but no bio connect port is ever visible there.
Although Lily says that she has no control over the Invisible Memory, she activates the invisibility with a click of her fingers as she leaves Isaka's office, indicating that he altered it for her, despite his plans for the Memory.
