Carol was never an X-Men officially The only reason Carol was with X-Men from UXM# 150-171 was because she was recovering from her close encounter with Rogue. In UXM#164, after her transformation into Binary, Peter asked her to join, but Carol gave him an ambivalent answer. When Rogue showed up in #171, and Xavier accepted her, Carol stated: "I have nothing to lose here, charles, no real ties break.That makes my decision easy. I am not an X-Man--and all of a sudden, I'm glad!" But even Claremont gave a indecatetor of Carol someday returning sometime in the future in the issue. On the last page, Rogue asks "Will she (Carol) be back?" Kurt answers "In her own time, perhaps, fraulein, when the hurt is less".
