I’m afraid I don’t understand how there’s going to be a civil war in the Marvel universe, at least not on movie theaters… HYDRA’s exposed and on the run. Everyone on Earth already knows the secret identities of every Avenger (and SHIELD member) with the exception of Falcon, Ant-Man, Wasp, and Vision. …so the “no more secrets, everyone reveals themselves” match is no longer there to set the Avengers aflame into a civil war.
