Yes, I believe Storm will be the person Jean will fight and unlike others I'm here for it!! I know Storm has psi defenses, but I'm sure that Cassandra can bypass that rather easily. I feel she is of a greater threat than just the small range plans of others psychics like ShadowKing. Her treachery knows no bounds so of course she'd go after both women that caused her problems during Morrison's run.

Also they picked Wakanda to be in and yeah, that could be because of Gentle (which I have no problem with X-23 not knowing more intimately...not like he was her bestie there in New X), but he may be a key in fighting Storm. Also I get to see Storm finally interact with Jean since her return so theres that....Jean also won't go all out on her "sister" and will have to use her TK or her wits to win that kind of fight...and that's not to say that Storm herself won't be fighting for control of herself from the inside. With a title called Storm Rising, it has to be her.
