Yeah, Taylor wrote Adamantium Agenda - the book with the reunited core Bendis New Avengers and X-23 - not Mystery in Madripoor.
Yeah, if this version of UXM had happened, New Avengers and U.S.Avengers as well as No Surrender wouldn't have happened. Not in the form we got anyway. I wonder if THAT's why it was nixed. After all, New Avengers's AIM storyline was set up in Hickman's Avengers.
