Discovery finds a structure between two black holes, and Burnham plans a heist aboard a rival's dreadnought.
Discovery finds the Progenitor structure at a Lagrange point between two primordial black holes, but Moll and the Breen seize it first and discover a portal inside. Primarch Tahal, responsible for the deaths of Rayner's family, moves to take over Ruhn's forces, and Saru volunteers to hold off her fleet.
Burnham boards Moll's dreadnought with Book, Adira and Rhys, and Adira brings down its shields. Burnham and Book secure the structure and talk through their relationship. When they are found, Discovery rams the shuttle bay, pulling everything into space, and Moll, carrying L'ak's body in a pattern buffer, and Burnham pass through the portal before it is torn away. Jonathan Frakes directed.
