Kate alone. The Hollowing whispers. Kate whispers back: "I know what you are. I know what you want. You will not have me." The Hollowing laughs. "We will see, little door."
Kate confesses to Chelsea about the Hollowing voice in her head, finally sharing her darkest secret. Chelsea responds with unconditional love and support, promising to fight alongside her.
Chelsea visits Marcus. He is worse - coughing blood now. Marcus: "The child is already gone. What is left is the question - weapon or victim?" Chelsea refuses to accept either.
Rylee demands options. Lucas: "We can try to sever Kate connection. Might kill her. Or we use her until the Hollowing takes her completely." No good choices.
Lucas tells Kate, Chelsea, key staff about original incursion. Dominion. Enslavement. The Hollowing as weapon. How humanity closed the portals. Cost: everyone who touched the seal died.
Lucas tells Alexis the truth. The original portal closers did not survive. They became the seal. If Kate keeps getting closer to Hollowing... Alexis: "We have to tell her."
The Hollowing is patient. Shows Kate her fears - abandonment, being used, dying alone. Then shows her the alternative. Power. Purpose. Family. It is lying. Kate knows. But the lies are beautiful.
Kate collapses during lunch. Thirty seconds of nothing - eyes open but no one home. When she comes back, she has drawn something on the table. Coordinates. A place in space.
Lucas pulls classified files. The original Hollowing incursion. The people who stopped it. Symptoms before the end - exactly what Kate is showing. He needs to warn them.
