So time is an illusion and nothing makes sense, got it.
Unfortunately I can't blame this all on Steve. Hell, we're all to blame, even you. We made some mistakes that ended with civilian casualties and as a result, the U.N. wanted complete control of the Avengers. I'm talking: where we can go, where we can't go, power to command us where to go, how we are to do our jobs. Total control for the sake of "accountability". They had a whole document drafted up and ready to be signed in 3 days.
But, things went south when the king of Wakanda was assassinated before the Accords could be signed and we learned about the other Winter Soldiers still on ice, courtesy of a man called Zemo. He framed you for the assassination, by the way. Our half of the team wanted to stop him from waking the Soldiers up, the other half--the half that agreed to let the U.N. put a leash on us--came to stop us.
We were able to give you and Steve the chance to get away to stop Zemo but the rest of us landed in a supermax prison for enhanced individuals in the middle of the goddamn ocean.
