Collider argues that Marvel’s reported casting of Samara Weaving as Emma Frost, following Sadie Sink’s apparent debut as Jean Grey in Spider-Man: Brand New Day, could establish a major X-Men rivalry in the MCU. The article says this matters because Emma, Jean and Cyclops have a well-known and emotionally complicated history in the comics that has not been fully explored in live-action adaptations.

Emma Frost is described as a powerful telepath who began as a Hellfire Club villain before becoming an X-Men ally and teacher, while Jean Grey is traditionally Cyclops’s partner. The suggested storyline would see Emma develop feelings for Scott Summers, creating a love triangle with Jean; January Jones previously played Emma briefly in 2011’s X-Men: First Class.
