"-I don't know about that, but it is powered by the Cube" -Nick Fury

(looking at the Chitauri Scepter, as it glows significantly more than previous) "-what we have here is more powerful than any of them ever knew" - Wolfgang von Strucker

Marvel is trying to tell us something. As of now, it is unclear of the Maximoff Twin's origin. They could be Inhumans, but I don't think that's the case, I think they were exposed to the Chitauri Scepter's power under HYDRA's manipulation and experiments. I think the reason Fury and the Avengers mistook the Tesseracts power as the Scepter's is because they are both Infinity Stones, they were created by the same force at the same time, of course they give off similar power. But, no one had studied the Scepter before, only the Tesseract was being studied. The Scepter had only been on Earth for a short period of time. But after examination by HYDRA, they realized it was self sustaining, but has exactly the equal powers of the Tesseract. They might have tried to turn off the Scepter, the Tesseract was in Asgard, it should have worked. Also, Fury didn't know that the Scepter was powered before Loki arrived on Earth. The Scepter is also to play a big part in Age of Ultron. It's even in the trailer. And the LEGO sets contain the Scepter, and the LEGO sets from the Avengers were based off of actually scenes in the movie.
