I kinda miss the old snobby, evil Emma from Hellfire Club.
She would make an excellent villain for both Scott's team and Wolverine's team. But of course, she will need her telepathy back for that. Hopefully made even stronger by the Phoenix Force possession, which unfortunately is not the case right now.
I just don't like the soft, caring version of Emma we have these days. I liked Emma the most when she was a villain.
