Life, Itself
Summary
The portal takes Burnham and Moll to a higher-dimension structure where Burnham convinces Moll to work together. Book and Culber hold the portal with a shuttle's tractor beam using knowledge Culber inherited from Jinaal, and Saru convinces Tahal to stay away though she sends a scout ship to investigate. Burnham accesses the technology and connects with the consciousness of a Progenitor who explains that she is free to use the technology but it cannot bring L'ak back to life. Burnham leaves with Moll as the Discovery crew use their unique spore-based propulsion system to send the Breen dreadnought and Tahal's scout ship to the edge of the galaxy. Burnham decides that no one should control the Progenitors' technology and releases the portal into one of the black holes.
