No, I mean I genuinely don't know why Steve was mind-wiped and exiled from the Illuminati since I didn't read any of their stories and didn't even know they existed until Original Sin. What was the in-story reason? Was Jonathan Hickman the person who wrote the former's mind-erasure?

Also, considering Steve was Director of S.H.I.E.L.D., who's to say he didn't have any people working on ways to stop or survive the Incursions while he brought the Illuminati to justice? What did MARVEL rip off from DC, may I ask?
