She wasn't taken because I wanted to keep her around longer. The in-universe explanation was that no one else was in the infirmary with her, and thus she never talked, saying all that stuff about time travel. Thus the military was never alerted, and she stayed. She joined Team Victory because 'Brainzilla' is a different person from Izzy, and Team Victory has less people (but Team Amazon will gain an additional member when Ezekiel re-joins in I See London...)
