Captain America: Civil War - 12 Most Hotly Anticipated Scenes

The Scene: Scarlet Witch uses her considerable powers to exercise control over Vision in the heat of battle.

Why It Should Be Awesome: Because it's pretty clear from cast and crew interviews that there's going to be at least a vaguely romantic arc between these two characters (as per the comics), so seeing the two actually fighting each other should add plenty of high-drama to proceedings.

Also, it'll be interesting to see a character as ridiculously powerful as Vision get dominated, all the more so because it's by another Avenger.

What Could Go Wrong: It could go full Joss Whedon and end up feeling cheesy or overly melodramatic, or Scarlet Witch could possess Vision and then do absolutely nothing interesting with him.
