It would be ideal if Marvel used Wanda (with or without Pietro) in an Avengers sequel before Fox decides to **** them over in one of its wretched X franchise films. The way Fox operates, I wouldn't put it past them to tell Vaughn to use the Scarlet Witch and Quicksilver solely to ruin Marvel's chances of ever including them in The Avengers. (And based on the way Vaughn's last film treated female characters, Wanda would probably be a stripper with Pietro as her manager.)
But then the question becomes... if Scarlet Witch really breaks out in an Avengers sequel, wouldn't Fox just immediately turn around and put their own version of Scarlet Witch in their movies anyway?
