Ms. Voughts absence is quite noticeable from the current HoX/PoX books given her history with:
Charles Xavier
Magneto
Exodus
Charles has been nothing but a massive a-hole to her from the get go right through to her last appearance in Legacy. As a result she chose a different way.
Would Vought be as accepting of being lead by Xavier as the others?
And if not is she sipping tea halfway across the world with Danger?
