It seems Elizabeth Olsen is well-versed in the comic book connection between her character, Scarlet Witch and Paul Bettany's Vision. However, the connection between those two in
Captain America: Civil War won't purely be romantic.
"I think there’s something unique in the fact that her powers come from the same thing that powers him, and that is how we’ve made them have that kind of… that specifically in common, as opposed to it being something else that the comics kind of created, which has been pure romance. But they do have something uniquely special because of that."
Though the end of
Avengers: Age of Ultron showed Vision and Scarlet Witch among Captain America's
New Avengers, it appears they will be on opposite sides of the conflict between Cap and Iron Man.
If certain rumors are to be believed, the mind Stone will have a pretty significant development in the film that stems from the relationship between Vision and Scarlet Witch.
Civil War opens in US theaters on May 6.
In The Avengers (2012), Thanos gives Loki a scepter that allows him to control people's minds. After Loki's defeat, it comes into the possession of Hydra leader Baron Wolfgang von Strucker. The mid-credits scene of Captain America: The Winter Soldier (2014) reveals that von Strucker has been been somehow using the scepter on humans to unlock superhuman abilities. The only two surviving subjects of these experiments were Quicksilver and Scarlet Witch. In Avengers: Age of Ultron (2015), the scepter is revealed to contain the Mind Stone, which Ultron incorporates into his "Vision", a synthetic android.
In the comics, Vision and Scarlet Witch become and item and eventually marry, despite the fact that Vision is a robot.Wanting to have a family, Scarlet Witch uses her powers to have two children and she and Vision leave The Avengers.
