Marvel has been pretty hush-hush when it comes to Captain America: Civil War. We haven't received much solid information other than multiple rumors and speculations about the plot. One thing that has been heavily speculated on is Vision's true allegiance during the climatic battle of superhero teams.
A theory surfaced a while back that suggested, due to Vision and Scarlet Witch's intimate relationship, he would inevitably switch teams and join Captain America's squad. While this initially began as a rumor, Paul Bettany's recent comments may have just supported it.
Did Paul Bettany confirm the rumor?
Paul Bettany was doing a bit of promotion with Collider when he made some comments about his character, Vision, and the script of Civil War...
“What I love about my character is that there are so many places for him to go,” he said. “I think he’s very interested in what it means to be human and what love is. The only way one can guarantee one’s loyalty is love. Loyalty is beyond logic, really. Logic doesn’t really provide for loyalty. If your logic changes suddenly and things not make sense, you can alter your allegiance, but love stops you from being able to do that.”
The big takeaway from that statement, to me, was when he said, "The only way one can guarantee one’s loyalty is love."
It seems that Vision's loyalty will be in question when he sides with Team Stark, opposite of his love interest, Scarlet Witch. This is a battle internally that Vision will have to deal with as he begins to feel more and more humanlike.
So, yes, I think it's pretty likely that he will be switching his allegiance in Captain America: Civil War.
I really believe in this theory, especially now that Paul Bettany made these possible spoiler-rific comments. It makes a lot of sense and seems very likely that this is how Civil War will shake up. Cap's team, on paper, seems at an extreme disadvantage and Vision could balance things out a bit.
Hopefully you are decisive and know what team you stand on when [Captain America: Civil War](tag:994409) begins on May 6th, 2016!
