Science Bros.
All of our Avengers know how, so at least me, Janet, and Pepper. Whatever equivalent might exist in that other timeline, the ones where the Avengers that look like us are from might know too if they've had a similar event. Abomination went wild on New York and there wasn't a choice. I don't like locking people up, but sometimes you have to step the hell up and do what is necessary. One of the less damaging things we've done over the years if you ask me.
