Marvel are notoriously secretive, but a digital comic has shed some new light on one of Avengers: Age of Ultron’s biggest mysteries. That of course is the origin of Quicksilver and the Scarlet Witch, “The Twins” in the clutches of HYDRA who we met in the mid-credits scene of Captain America: The Winter Soldier.

As it turns out, Baron von Struker didn’t kidnap them. They’re willing test subjects who volunteered, and the villain used Loki’s sceptre from The Avengers in order to unlock their abilities. “Unlock”? That sounds an awful lot like what’s been happening to people in Agents of S.H.I.E.L.D., and adds further weight to the theory that Quicksilver and the Scarlet Witch are in fact actually the descendants of The Inhumans.

In the comics, “The Twins” are the mutant children of Magneto, but only Fox can address that in their movies because of some complicated rights issues. Transforming them into Inhumans in the MCU makes sense.

The comic also reveals that Strucker is based in the fictional European nation of Sokovia, and those protesters we saw in the Avengers: Age of Ultron trailers are recruited by him with the promise that HYDRA can given them the power to overthrow their government; Quicksilver and Scarlet Witch are the only ones he succeeds with though, likely because the Infinity Stone somehow unlocks their latent Inhuman genes.

Another revelation is that Strucker stole Loki’s sceptre because he was masquerading as a high-ranking S.H.I.E.L.D. agent before the espionage agency fell. Check out a couple of pages from the story below!
