Just when they think they have a handle on their powers, The Void infiltrates the school, and the girls discover that one of them has been secretly feeding information to the enemy. Tension mounts as they race to uncover the traitor before The Void strikes. In a heart-wrenching twist, Jean is revealed to be the betrayer, but only because the Phoenix Force within her is corrupting her mind. She's torn between the power of the Phoenix and her loyalty to her friends.

As the girls grow closer, they discover an organization called The Void—a shadowy group that hunts people with special abilities to harness their powers for a sinister cause. When The Void infiltrates New Avalon, the girls face their first real battle, forced to defend their classmates from rogue agents.

During the attack, Jean begins losing control of the Phoenix Force, nearly destroying the school. The others manage to subdue her, but the battle leaves the school in ruins. Jean fears her powers might make her a danger to everyone.

Jean: (crying, glowing with Phoenix energy)
"I almost killed you! This power... I can't control it."

Scarlet: (putting a hand on Jean's shoulder)
"We'll figure this out together. None of us can do this alone."

The group continued to train in secret, but Jean's control over her powers began to slip. The Phoenix Force wanted more than just protection—it wanted dominance. During a school event, Jean accidentally released a burst of energy, destroying part of the school.

Jean: "I... I didn't mean to... I can't control it anymore!"
Scarlet: "We'll figure it out, Jean. We're in this together."
Natasha: "Are we? We can't keep hiding this from everyone. They'll come for us."
Carol: "The more we try to control it, the worse it gets."

Jean became more distant, and her bond with the group weakened. Meanwhile, The Watch approached her in secret, offering to help her harness her powers—for a price. Desperate to protect her friends from the Phoenix's destructive influence, she agreed, unknowingly betraying them.
