In X-Blue #8 where Emma shows up shes going to be getting a new costume and Marvel says she isn't a villain...
"It was always our goal to bring Emma back into ‘X-Men: Blue,'” the editor said, saying that while Frost has been through some dark times of late, she’s not turned into a villain.
The editor also said that Emma will sport a new costume inspired by her classic White Queen style, and the diamond form of the character will be breaking back out as she clashes with Hydra."
