I'm a little confused. This article makes it sound like Emma knows Moira MacTaggert is alive, about her mutant power to reincarnate, and about the multiple timelines: https://www.cbr.com/x-men-emma-frost...l-after-moira/.
But, so far as I know, the only three people who know about Moira and her power and the danger it poses, are Xavier, Magneto, and Moira herself.
Have I got this wrong?
