After they permeate Cassandra’s consciousness, Jean and Emma embark on a psychic journey, but are plagued by hostile manifestations of Cassandra’s personality.

Emma quickly becomes detained, but Jean presses on.

Jean locates Professor Xavier’s psyche and discovers that Xavier tried to kill his twin sister while they were both in the womb.

Once Jean and Emma regroup, they travel back out of Cassandra’s mind and Jean reveals her findings to the rest of her teammates.
