One of the bones people picked with Avengers: Age of Ultron was the lack of explanation behind a couple of new characters' powers. The Vision and Scarlet Witch seemed both limitless and unpredictable to certain extents.
This won't be the case in Captain America: Civil War, at least for Scarlet Witch.
“We find Scarlet Witch without a home, without a family, and she ends up creating a surrogate family within the Avengers and making a decision to be a part of the team," says Scarlet Witch actress Elizabeth Olsen. "I think a lot of that has to do with Jeremy’s character – like his attitude towards her and the speech he gives her at the end of the film. So we pick up with her having started a new life, but still trying to figure out what her abilities are and if using them causes greater good or greater damage.”
Captain America: Civil War is certainly setting the stage for Infinity War in a number of ways between its massive cast and Russo Brothers' direction. However, Civil War will remain grounded and consistent with the tone of Captain America: The Winter Soldier, seeing as it is, after all, the third installment of the Captain America trilogy. For that reason, Joe Russo wants to keep all things grounded and seeming physically realistic in Civil War and hold off the cosmic madness until 2018.
“We like characters that have limitations to their powers, so there’s a cost for everything that they do,” Joe Russo says. “Wanda can’t fly, she can use her power to push herself off, launch and then bring herself back down. But she has to stop herself and it’s not the most graceful version of flying. It’s just using her power to create energy to push herself up and bring herself down, but she’s still subject to gravity.”
