A blast from the past: Dani Moonstar is back! But is she friend or foe?The Mutant Liberation Front has taken over a cancer research center in St. Louis, based on a tip that mutant-specific viruses are being developed there. Outside, a Zero Tolerance force surrounds the clinic. Inside, Wildside doesn't accept his tip was wrong and Locus teleports, leaving the MLF for good. The ZT commander, Ekatarina Gryaznova, allows a news crew into the research center, knowing full well they are really Domino, Sunspot and Siryn in disguise and are heading into a trap. At the Xavier Institute, Cable discusses Caliban's recent seizures with him. Outside the research center, the Zero Tolerance force captures Meltdown, Shatterstar and Rictor, while inside, three of the hostage researchers revel themselves as Prime Sentinels. Back at Xavier's, Ozymandias visits a sleeping Caliban, musing about Apocalypse's plans for the former Morlock.
