Five words to strike fear into the hearts of spies and evildoers everywhere: Jamie Madrox, Agent of S.H.I.E.L.D. Except that when Madrox decides it's time to start gathering in the stray dupes that are still wandering around, the S.H.I.E.L.D. agent doesn't especially want to go...and S.H.I.E.L.D. isn't especially inclined to let him go. Plus: Peter David and artist Pablo Raimondi evoke memories of the classic "X-Aminations" with "Re-X-Aminations" as the new team unloads their hopes, fears and darkest secrets to an attentive Doc Samson.
