The more Rogue uses her mutant power, the more her mind becomes filled with fragmentary psychic echoes of the people she absorbs. The permanently absorbed Carol Danvers (Ms. Marvel) is a completely distinct, albeit dormant, personality in her head, and the Mastermind subtly exacerbates Rogue's psychological distress as a means of revenge against Mystique. Desperate, Rogue turns to Professor Charles Xavier and the X-Men for help. The Professor is unable to do a psychic scan of her, due to the clashing human and Kree portions of her psyche, but nonetheless decides to not only welcome her into the school, but make her a probationary member of the X-Men. The X-Men threaten to leave the school should Rogue be accepted, even though none of the active members aside from Storm and Nightcrawler had even met Rogue before. However, Xavier is adamant and convinces the X-Men to stay.
