History Fridge / KamenRiderDouble

** This can sort of be seen with [[spoiler:Nazca R, though the fact that the Memory can evolve might joss that]].

** Actually, the T2 Memories have steel-colored tips, while the Joker Memory from the last episode is shown multiple times to have a gold one, confirming it to be the T1.[[hottip:* :Yeah, I bet you didn't know you could [[FridgeLogic put a gold tipped Memory in a silver slot]].]]

* This could also count as a TearJerker, but it works reguardless. Take the Spider Dopant's curse into consideration (in which if you touch the ones you loved, they'll explode) and how [[spoiler: Narumi had this curse, even when the Spider Memory is broken]]. There's a scene in Begin's Night where [[spoiler:Narumi slaps Shotaro]]. Notice how he didn't blow up after that? With this in mind, the conclusion soon becomes clear: [[spoiler: Narumi never really loved Shotaro, or at least as much as he loved Akiko]].

* How come they reuse the Dopant Memories from the beginning of the show in the finale and in one of the spin-offs? Because there's no one to make more Gaia Memories, so you can't have find a unique memory unless you happen to have a Gaia Memory ''before'' the crackdown (like the Commander Dopant), find a rare one ''after'' the crackdown (like the Energy Dopant). If you don't have those, you would opt for one of the ''many'' mass produced Memories, which happen to be the ones seen in the beginning.

* The [[KamenRiderDenO Cho Den-O Trilogy]] comprises Episodes Red, Blue and Yellow, starting at the same time that Accel Trial debuted. So Accel, already red, turns blue, referencing two parts of the trilogy - so what about Yellow? Well, Accel in yellow was teased for some time since he turned yellow before going Trial for no real reason (until Double Returns: Accel), which is quite appropriate as Episode Yellow is about [[KamenRiderDecade Kaito/Diend]], who ISN'T EVEN YELLOW, and ends with Kaito [[{{Trolling}} going right back to his old ways]], with none of the resolution in Red and Blue.

** The same logic applies to Accel Booster: B[[hottip:* :Booster]] is the letter after A[[hottip:* :Accel]].

** Given that quite a few times he's the ''victim'' of slapstick violence during the course of the series, it could be a reflection upon that rather than his own possible violent tendencies.

* How did Kamen Rider Skull take on the Terror Dopant without being terrified in the Nobody's Perfect PV? He's hard-boiled, as in unswayed by emotions. Fear is an emotion.
** Whereas his apprentice is terrified because he is ''half''-boiled.
* Why does TheMovie have so many names? [[SpellMyNameWithAnS Double Forever, A-to-Z, The Gaia Memory Of Fate]]. It doesn't. It just has one: (Kamen Rider Double) Forever A-to-Z: The Gaia Memory Of Fate.

* In "The Girl A", Phillip can somehow look up the way Asuka's father said goodby to her in the Gaia Library. Which can be handwaved by the Gaia Library somehow covering all existence - or maybe because enough reporters made sure to capture Asuka's father doing that on camera. It's good propaganda.

* In the ''Forever A to Z'' Net Movies, it's revealed that the Queen Memory can turn anyone into Queen - could the reaction over the actual Queen trying to use the T2 Queen Memory in the movie a justified attempt at averting DivideByZero?

* In "Forever A to Z", all the T2 Drivers seek out the people in the city they're most compatible with. So what does it say about Watcherman that he's singled out by the Violence Memory?

** The same logic applies to Accel Booster: B (Booster) is the letter after A (Accel).

** It's also a punny name, based off Double's Cyclone Joker finisher, Joker E''xtreme''.

* Ever wonder why you hear a sort of military motif in ''Stay The Ride Alive'', as well as see a bunch of soldiers in the music video? Well, consider how the movie this song was made for dug into more of the event that cost Shotaro's mentor his life. Couple this with Tsukasa's death in his portion, and it makes sense that this gives off vibes of a soldier's funeral.

* It is possible that every single thing done by Shroud was to prepare Philip and Ryu for Cyclone Accel Xtreme. Philips body was weak and he did not know how to fight, so he is paired with someone who can fight and look after him (possibly meant to be Sokichi). CAX runs on rage, and so Fang uses Philips body and send him berserk so he can learn to deal with this rage in combat. Ryu is given Trial to get him used to increased power, and the engine blade because he will use a sword in CAX. The Prism beaker takes 4 memories despite Philip and Shotaro having six because out of the normal shape ones they would have 4 between Philip and Ryu. Last Philips memories can be considered to match up with the modes of the engine blade; Cyclone=Jet, Luna=Electric and Heat=Steam. CAX was not just the latest idea Shroud had She had been planning for it from when she first met Ryu and hired Sokichi.

*** That's the case- and the [[spoiler: Spider Dopant outright says it'll kill the person the victim loves MOST. It makes sense that Soukichi loved his daughter more than anyone else, regardless of how much his protege meant to him.]]

** That or [[spoiler: it only works on Akiko]].

* This could also count as a FridgeSorrow, but it works reguardless.

There's a scene in Begin's Night where [[spoiler:Narumi slaps Shotaro]]. Notice how he didn't blow up after that? With this in mind, the conclusion soon becomes clear: [[spoiler: Narumi never really loved Shotaro, or at least as much as he loved Akiko]].

* Shotaro's favored Memory, '''Joker''', is said to possess the inherent power of the "trump card". Why should this be considered PersonalityPowers? [[spoiler:Shotaro is actually the ''wild'' card, being the outlier in both {{The Chessmaster}}s' plans. What's the wild card in most card games? '''Joker'''. Being the metaphorical Joker is what ''makes'' Shotaro the trump card, as his [[{{Determinator}} sheer determination and devotion to]] [[TrueCompanions his friends]] allowed him to pull off the impossible and shake off the paralyzing fear inflicted upon him by Terror and defeat Utopia single-handedly without transforming, things Shroud's chosen warrior (Ryu) couldn't even do.]]

* I thought it was weird how the Cyclone Dopant had that huge yellow rider-esque eye. Then when you find out who their relationship with Daidou Katsumi/ Kamen Rider Eternal it makes so much sense! [[spoiler: [[FamilyEyeResemblance He has his mother's eyes!]]

* The Foundation X plot was left hanging to follow it's FilmNoir theme. Old [[RaymondChandler mystery works]] would have many questions unanswered intentionally, and would be [[BittersweetEnding bittersweet]] at best.

** [[spoiler: Even more easier if he partnered up with Phillip to begin with as Shroud wanted]].

** [[spoiler: Even more easier if he partnered up with Phillip to begin with as Shroud wanted]].
* The ''KamenRiderDouble'' series has 'Shotaro's Delusion Diaries', comedic shorts featuring Shotaro having bizarre daydreams. In one delusion he visualizes the agency in 2060. He and Akiko are old, Ryu's haunting the place, and [[spoiler: Philip is exactly the same since his body is made of data and can't age.]] Obviously this 'future' is uncanonical and silly, but if the last part is true [[spoiler: that means that Philip is going to watch his friends grow old and die around him without aging a day himself. [[WhoWantsToLiveForever A little depressing to think about.]]]]
