*Minor spoilers for Captain America: Civil War lurk within*
We're going to discuss this by dropping as few spoilers as we can, but we will be discussing a non-plot related, but pretty big Infinity Stone related reveal which occurs during Captain America: Civil War.
So if you don't want to know, then get outta here! And if you're okay with knowing, take this adorable GIF of Chris Evans getting the stars and stripes scared outta him on Ellen by a guy dressed as Iron Man to decide, and if you're still cool with it, then read on.
Scarlet Witch and Vision
Elizabeth Olsen's Scarlet Witch was undoubtably one of the breakout characters of Captain America: Civil War.
After her bumpy introduction in [The Avengers: Age Of Ultron](tag:293035), the new Marvel movie continues the story of her struggling to come to terms with her powers, and expands on her relationship with Vision (Paul Bettany), which is less "will they wont they?" and more "are they aren't they?".
Comic fans will know that, in the books from which they hail, Wanda Maximoff and Vision develop a relationship and eventually are married (though sadly a series of tragic, reality altering breakdowns ended that marriage). The question of whether or not we'd see something spark between the former antagonist and synthetic android has been tossed around ever since Vision rescued Wanda from the falling wreck of Sokovia in Age of Ultron.
Civil War didn't really answer that question, though there were plenty of hints towards a pre-existing affection between the two new Avengers. But it did raise another question — a pretty damn huge question actually.
The Infinity Stone
Age of Ultron previously established a connection between the two characters, as both their powers stem from the Mind Stone, extracted from Loki's scepter. Whilst Vision carries the Mind Stone embedded in his forehead (Adam Warlock style), both Scarlet Witch and her twin Quicksilver / Pietro (Aaron Taylor-Johnson) received their powers from Baron Wolfgang von Strucker's (Thomas Kretschmann) experiments with the same scepter and stone.
Prior to the release of Civil War, Elizabeth Olsen spoke a little about the connection between the two Avengers and hinted towards common ground in terms of the Infinity Stone connection:
: "You learn a little bit more about what connects [Wanda and Vision] in [Captain America: Civil War]. And I think there's some really sweet moments between Paul [Bettany] and I, and it's more about how they relate to one another and their similarities just based on their superpowers."
But of course, Vision and Scarlet Witch do end up on opposite sides of the schism in Civil War, and it was during the scene where Vision attempts to stop Wanda leaving the New Avengers Facility (which we saw previously in the second trailer) that something pretty major occured.
Scarlet Witch uses her, still pretty undefined, powers to subdue Vision, taking over his body and forcing him to the ground. But when she does, something very interesting happens to the Infinity Stone embedded in his forehead.
Specifically, the yellow colour of the gem is taken over by the red of Scarlet Witch's energy manipulating ability as she forces Vision down. Her power takes over his entire body, and the very Infinity Stone itself.
So What Does This Mean?
Vision's very life force is powered by the Infinity Stone, so removing the stone from his body would likely kill him or otherwise shut him down. But Wanda is unique in that her powers were born from the stone and now exist independently of it.
The MCU Scarlet Witch has been massively powered down from her comic book counterpart. The cinematic Scarlet Witch has demonstrated telekinesis along with the power to manipulate minds and project energy, whilst her comic book counterpart's powers have changed greatly over time — they've fluctuated from vague witchy hex powers, to the ability to alter and remake reality as she saw fit.
It's hard to read exactly what this event means, as we only saw it for a few seconds, but it's pretty likely that this is a sign of her growing powers. And Scarlet Witch being able to take over — and possibly even control — the Mind Stone has huge implications for the upcoming [The Avengers: Infinity War](tag:738027).
So far she's the only one of the Earthbound Avengers we've seen show the ability to control an Infinity Stone. Few people have come directly into contact with one and — as seen in Guardians of the Galaxy — doing so is usually fatal.
Without spoiling too much regarding the end of Civil War, Scarlet Witch is taking even bolder new steps out into the world, and we're not expecting to see her again until the Infinity War two-parter (apart from the Doctor Strange cameo we're holding out hope for, the two characters being very closely associated in the comics).
When Infinity War rolls around, being in possession of a power which could challenge and control an Infinity Stone is a huge revelation — and could go a long way towards turning the tide of the battle towards the Avengers favor when Thanos comes to town.
Unfortunately the answer to that question is still a long way off, as Avengers: Infinity War - Part 1 isn't set for release until May 4, 2018.
