Marcus dying. Chelsea at his side. Final words: "She is still Kate. Fight for her. But if she is gone... end it quick. Do not let her become a door." Marcus dies. Chelsea weeps.

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.

Lucas confronts his survival and transformation. Kate predicts team separation. Marcus reflects on his choice to stop recording. Shuttle approaches Endeavor and docks. Dr. Yun detects biological anomalies. Team quarantined in separate isolation units.

Alexis Chen monitors Kate's transformation from the analysis center, watching as the girl's energy signature reshapes the galaxy by collapsing every warp route and neutralizing the Hollowing.
