When a dimensional rift dumps Ben Tennyson straight into the middle of a massive Hydra ambush, the Avengers expect to rescue a civilian kid.

Standing among the smoking wreckage of alien-tech tanks, Earth's Mightiest Heroes are left completely baffled by this teenager who has absolutely no intention of running away from an interrogation.
