One detail from the original script of Marvel Studios’WandaVisionseries makes one hugeMCUpower theory much more likely, perhaps explaining exactly how Quicksilver got his powers beforeAvengers: Age of Ultron.Elizabeth Olsen’s Wanda Maximofftook center-stage for the first time in 2021’sWandaVision, and more of her history in the MCU was revealed during the pivotal episode 8, “Previously On.” Agatha Harkness took Wanda on a journey down memory lane, but Marvel still left out some details from the episode’s original script.
Wanda Maximoff debuted in the MCU alongside her brother,Aaron Taylor-Johnson’s Pietro Maximoff, a.k.a. Quicksilver, over a decade ago. WhileWandaVisiontried to explain some unanswered questions concerning the Scarlet Witch,Quicksilver’s backstory and originsare still shrouded in mystery, butWandaVisioncame close to addressing them.One hidden detail in the original script forWandaVisionepisode 8 could have supported a huge Scarlet Witch and Quicksilver theory, which makes their possible returns to the MCU even more exciting.

WandaVision’s Script Suggests Scarlet Witch Really Did Give Pietro His Powers
Pietro Maximoff Was Not Born With Powers In The MCU
The original script forWandaVisionepisode 8, “Previously On,” as revealed byProlix, seems to see Agatha Harkness reveal that it was indeed Wanda Maximoff who gave her brother his speedster abilities, ensuring that he survived HYDRA’s experimentation on the Mind Stone.Agatha notes that Wanda"protected him… long enough to get some powers out of the deal,“which supports the well-known theory that Quicksilver’s powers were not innate. WhileWandaVisionexplained thatWanda Maximoff was born a witch, Pietro’s powers were not explained, but this may now have changed.
For decades in Marvel Comics,Wanda and Pietro Maximoff were depicted as the mutant childrenof Magneto. However, this origin was retconned prior to the pair’s live-action debut inCaptain America: The Winter Soldier, as they were instead revealed to be genetic experiments of the High Evolutionary.This backstory was changed again for the MCU, making the twins products of HYDRA experiments with the Mind Stone, but the Infinity Stone was then revealed to have only enhanced Wanda’s innate witch powers, which couldn’t have been the case for Quicksilver.

The WandaVision Theory Could Prove Just How Powerful Scarlet Witch Really Is In The MCU
Wanda Maximoff May Have Given Her Brother Powers
BecauseQuicksilver’s power-set has remained a mysteryfor several years, a popular theory emerged suggesting thatWanda Maximoff may have used her newly-enhanced powers as the Scarlet Witch to bestow superhuman abilities on her brother. The emergence of his own powers would have convinced HYDRA to spare Pietro Maximoff, considering him a success story in their Mind Stone experiments, though he soon met his demise at the hands of Ultron in 2015. This theory implies that the Scarlet Witch is far more powerful than first thought.

Wanda Maximoff’s ability to bestow powers on other individuals has been alluded to in the MCU, but never actually directly addressed. DuringWandaVision, Wanda magically createdher and Vision’s children, Billy and Tommy, who displayed abilities similar to their mother and uncle. Agatha Harkness, also a formidable witch in the MCU, bestowed superpowers upon Evan Peters' Ralph Bohner, though this was via an enchanted necklace. Marvel is perfectly primed to reveal that the Scarlet Witch gave her brother his speedster abilities, which may make their return to the MCU more likely.

Scarlet Witch Reveals Means Quicksilver’s MCU Return Is Even More Important
Aaron Taylor-Johnson Has Been Speculated To Return To The MCU
Wanda and Pietro Maximoff had basically no time to develop their sibling bond in the MCU before the latter was killed by Ultron in the eponymousAvengers: Age of Ultron. It would be fantastic to see both the Scarlet Witch and Quicksilver return to the MCU to develop their relationship, and this return could also confirm this wild power upgrade theory. In the lead-up toPhase 6’sAvengers: DoomsdayandSecret Wars, and the conclusion of the MCU’s Multiverse Saga,there has been speculation that both Elizabeth Olsen and Aaron Taylor-Johnson will reprise their roles.
10 MCU Actors We Desperately Want To Return In Phase 6 After Robert Downey Jr & Chris Evans’ Avengers: Doomsday Castings
Robert Downey Jr. and Chris Evans have been confirmed to be returning to Marvel in Avengers: Doomsday, and many more MCU veterans could join them.
After Aaron Taylor-Johnson’s recentdisappointing stint in Sony’sKraven the Hunter, which ultimately marked the end of Sony’s divisive Spider-Man Universe, it seems more likely he’ll reprise his role of Pietro Maximoff instead. After the fake-out of Evan Peters' return as Quicksilver from 20th Century Fox’sX-Menfranchise inWandaVision, it’s high time an official Quicksilver comes back to the MCU.Bringing Wanda and Pietro Maximoff back together could see the origin of their superpowers finally explained on-screen, with the Scarlet Witch perhaps being confirmed as the cause.
