Marvel Girl is tiring of the deceptions that Professor X perpetrates on the X-Men so casually. After her strange experience in space as her teammates and the Fantastic Four battled the Z'nox, the Professor has flown her to Muir Island to be inspected by his old colleague, Moira MacTaggart... but told the other X-Men that he was taking her to Boston.
Upon their return, they learn that Cerebro has located another mutant, this one close to Beast's home. He accompanies the Professor as they go out to make contact. But while they're gone, Cyclops manages to use Cerebro to close in on Warren's location. Aided by Candy Southern, Cyclops and Marvel Girl depart to rescue their comrade.
