>>80566061I get the impression from what Olsen has said, that she is worried her powers may do more harm than good.
Impression I get is she has to choose between the comfort of her surrogate family and dealing with her powers. "The safest hands are our own." -Cap
Her leaving and wandering alone (her name means wanderer..."gypsy witch" etc), is perfect set-up for her friendship with Stephen Strange.
She might do a Banner and nope the fuck out, Zemo might go after her when that happens and she then "discovers just how powerful she is" and warps to another dimension. Something like that.
Also makes Wanda/Vision a mirror of Steve/Peggy.
