In their darkest hour, Jean returns, but she is no longer the girl they once knew. She has embraced the full power of the Phoenix Force, and with it, her cosmic consciousness has expanded far beyond her previous limits. She warns them that The Void is a threat even the Phoenix fears, and that they must prepare for a battle unlike any they've faced before.

However, Jean's return brings tension. She is no longer just Jean—she is the embodiment of the Phoenix, and her intentions are unclear. Can they trust her, or is she just another threat?

Jean: "The Phoenix can help you. But it will come at a cost. Are you willing to pay it?"
Carol: "We don't have a choice."
Natasha: "What's the cost?"
Jean: "Your humanity."

The girls face an impossible decision—embrace their powers fully and risk losing their humanity, or fight as they are and risk being too weak to stop The Void. This internal struggle causes further division, as each girl grapples with what they are willing to sacrifice.
