Jamie Madrox comes face-to-face with the thing that terrifies him the most: having to make a decision. The divisiveness of Civil War has spread to his own team: Half of them want to cooperate with the government; the other half wants to take a stand against it. It's Jamie's choice that may well decide whether X-Factor stays together or cracks apart. And matters aren't being helped by Quicksilver, who offers Rictor the opportunity to get his powers back -- but at what price?
Plus: They've been a thorn in X-Factor's side since the beginning, and now things are coming to a head. X-Factor's newest assignment causes them to again cross paths with their arch rivals, Singularity Investigations. The result is revelations that strike to the very core of who and what Jamie Madrox is.
