That's really cool to hear that she does so well in her own private mini solos. She has a great reception when she shows up in other non-mutant books, too. She was well recieved in the Jessica Jones Purple Daughter book, the highlight for many people. She's great when she rams heads with the Avengers, and has great repertoire with tons of other heroes and villains.
Even if Emma doesn't marry Tony, I want her to be the center of that story and involved, heck, even involved in Iron Many 2020, so she gets more push. The year of Emma Frost is now!
