During his interview, Whedon confirms that Scarlet Witch's powers do not use hexes that bend reality to her will. Rather, she will be using telekinesis and some sort of fear-based psi power. Could this be an adjustment to the universe altering power Wanda Maximoff has in the comic book universe so that one hero isn't completely overpowered, eventually making Thanos that much more of a threat? Will the coming Civil War be sparked by fears brought out by Scarlet Witch? And, the big question, where do their powers come from? Are they magical (hellooooooo Dr. Strange!) or derived from an alien race, such as the Kree (hellooooooo Inhumans!) Only Whedon and the MCU powers that be can provide answers. Certainly, you won't be seeing completely world altering consequences from three whispered words in the MCU, thankfully. At least, not from the Scarlet Witch.
