My thought is she is suffering from the return of the Fireflight personality. This personality would not want her to remember a potential chance of it's death. The concept of absolute power corrupting absolutely is taking to the extreme. You get to see this in the actions of the Professor. Maybe it is a form of P.T.S.D. or short term memory loss. But I think the powers personality is another type of antagonist. One that fights the character inside their own mind.
