So, after a bunch of fast-paced issues, we finally get a nice, slow one that fleshes out what's going on. Apparently, we also have all the clues we need to figure out who's the culprit manipulating Stark...I don't know who it is, but I don't mind so far. As far as the thing in his brain; I wouldn't be surprised if it was his old techno-nervous center, as seen back in the Kaminski days, ala the same thing Kang used to control Stark during "The Crossing." Alternatively, it might also be a remnant from Stark's Ultron heart, which conveniently vanished around the time of Wanda's breakdown in "Avengers Disassembled." So far, though, I'm really liking this arc, especially the fact that I get a new issue every month (as opposed to the previous team). The Sentry/Iron Man showdown wasn't as grand as they had hyped it up to be, but again, the storytelling was good enough that I didn't mind much.
