History Fridge / WhatIf2021

** Crosses into FridgeHorror, every single person who warned Strange gave vague premonitions and basically told him to stop because they knew better than him. What did Mordo do? Angrily point out all the [[RealityBreakingParadox paradoxes]] that could've occurred if Strange had proceeded down his path ("Temporal manipulations can create branches in time. Unstable dimensional openings. Spatial paradoxes! Time loops! You wanna get stuck reliving the same moment over and over forever, or never having existed at all?"). Strange's universe may have been saved if someone had just told him outright what would happen and led to follow a different path to his quest.

** On the other hand, it's heavily implied that the effects of the Tesseract on the underground lake is what led the conquistadors to believe it was the legendary Fountain of Youth, which may mean the conquistadors had no ''reason'' to attack their village in any other universe.

* Kahhori's abilities (as well as that of her fellows from the Sky Realm) seem to primarily be a form of super speed, telekinesis, and later portal generation. Abilities that are perfect to inherit from the ''Space'' Stone, aka the Tesseract. All involve a form of ''moving'' things (or in the case of blocking bullets, ''stopping'' things from moving. Doubles the Fridge when you realize they seem similar (if not identical) to {{Film/CaptainMarvel|2019}}'s abilities, which were also inherited from the same source.

* The only discernible reason Kahhori and the Mohawk successfully fought off the conquistadors was because they had the power of the Tesseract. This suggests that in every other universe where the Tessaract doesn't get launched out of Asgard into North America, including the main one, Kahhori and her people were killed by the conquistadors.

* Peggy losing Steve after finally getting through to him seems like rubbing salt in the wound, until one remembers that in ''[[Film/AvengersEndgame Endgame]]'', Steve went back in time to live with Peggy and take TheSlowPath back. If this universe goes through similar events, Peggy might choose to do the same after said the war against Thanos, preventing his 'death' when assaulting the last HYDRA base (even if history still sees it as such) and otherwise staying off the grid. In effect, this knowledge gives the episode's ending a distant RayOfHopeEnding vibe, even despite her magically being kidnapped out of nowhere.

* Why during the scene with Strange learning time magic did the Ancient One and Wong show up instead of Mordo and Wong? Because the [=ST=] Strange sought out the mystic arts to heal his hands and was only experimenting with the magic out of curiosity, while Strange Supreme specifically wanted to bring back Christine with it. With her powers of foresight, it would be best guessed the Ancient One was there to stop Strange from probing further.

** It's also possible that they died at other other early points. One is in the Sokovian civil war along with their parents and thus never encountered Ultron in the first place. Two is that they died after the fight on the boat, when Wanda triggered the Hulk. [[HoistByHisOwnPetard It's entirely possible he struck and killed her instantly afterwards]].

* The characters who appear in the opening are the characters whose variants appear the most often in the season. Variants of T’Challa, Carol Danvers, Thor, Natasha Romanoff and Steve Rogers appear in four episodes and variants of Tony Stark appear in five episodes.
* Uatu filling his traditional role as an all-seeing narrator for this series seems to make Creator/StanLee's role as the Watcher Informant redundant, even if it was meant to be an in-universe explanation for his {{Creator Cameo}}s. But the Informant was only active in one universe. Now that there is an infinite number, the actual Watchers need to get involved in observing.

* The recap page notes under RuleOfSymbolism, how Gamora only identifies herself by name after her HeelFaceTurn, previously identifying herself only as daughter of Thanos. While extremely unlikely to be a direct homage, this does echo the novelisation of the ''Film/IronMan1'' in which, outside of Dialouge, Tony is exclusively referred to as Stark until Yinsen's death, the moment he truly turned from the Merchant of Death into Iron Man.

* Rocket is not with Groot on Xandar, so it’s quite possible he never escaped the [[Film/GuardiansOfTheGalaxyVol3 High Evolutionary]] in this universe.

* Loki arrives on Earth on ''Wednesday'' (Wotan's Day, aka Odin's Day), presumably on the orders of Odin (and Frigga), avenges Thor on ''Thursday'' (Thor's Day), and finally he takes over Earth on ''Friday'' (Frigga's Day).

*** This goes even further with her offense. As a woman, even though she's more well built than many of her contemporaries, she still would be found wanting in the size and strength department against many opposing soldiers. As such, her offense incorporated a lot of holds and forceful attacks at joints to help disable them. Once she received the serum she still initially fought this way…and proceeded to completely annihilate the limbs of most of her foes on her first time out with her new found strength. A combination of her prior experience, and her lack of restraint as she doesn't carry any reluctance of hurting others made her a demon on the battlefield. She notably makes small modifications to her fighting style after her first outing to avoid crippling enemy soldiers unnecessarily.
** It would also add another reason to Philips pushing for Hodge to receive the serum. If the serum didn't work on Steve they'd have put all that effort into a physical weakling who couldn't do much of anything. If it failed on Hodge they'd still have a soldier who could fight, and if it worked he'd be more powerful than Steve with the serum.

* T'Challa ends up every bit the [[MemeticBadass legendary outlaw]] that Sacred Timeline Peter Quill ''wishes'' he was. Why? Because even when he’s light years away from his kingdom, he’s still noble to his core.

* Any extremely powerful character introduced in later films that had been around before the events of Age of Ultron can also be assumed to be dead. As the episode shows, that includes Captain Marvel, but that also includes ones from phase 4 films and shows, such as the Eternals, Celestials, Clandestines, any of the gods in Love and Thunder [[spoiler:(perhaps including even Eternity, if The Watcher was also at risk)]].

* Kilmonger might not be able to hurt anyone anymore, but with him out of his own universe, there's no way to bring him justice, and no immediate hope to end the American-Wakandan war peacefully.

*** Alternatively, Uatu knows that Ultron would wipe out the horde, and so was using the Zombies as fodder, meaning naturally he wouldn't take the few survivors of the Zombie Apacolypse to die at Ultron's hands.

* If one thinks about it, the results of Arnim Zola getting his hands on the Infinity Stones could've been worse than one would expect. While Killmonger certainly intends to use the Stones for his own selfish agenda, and by possessing Infinity Ultron's armor he can evidently wield the Stones in multiple realities as Ultron had, the Stones' potential would probably be limited since Killmonger can solely use them to augment himself (or rather the armor he's wearing) into a god when taking them outside of their native universe. Zola is from the exact same universe as Infinity Ultron was and he's also a technological being with god-like powers at his disposal. So it's not out of the question to think Zola could use the Stones' full potential on their native universe to reshape it in a single sweep into a world where HYDRA dominates everything, just as the Sacred Timeline Thanos was able to use his universe's Stones to cause the Snap there in a single move; without any of the drawbacks Thanos had when trying to use them all at once.
