Star Trek: Discovery
Season 04
S04E13 - Coming Home
Tarka begins dismantling the power source’s container, causing dangerous plasma bursts. T’Rina learns that the minds of the 10-C are connected and they do not understand that Tarka is acting independently of Discovery. The crew sacrifices Discovery’s spore drive to escape the orb, but are unable to approach Book’s ship due to the plasma. Ndoye offers to make amends by ramming Book’s ship with a shuttlecraft, killing Tarka. Ndoye and Reno are beamed to safety, but Book seemingly dies. The crew of Discovery meet members of 10-C on a planet inside the hyperfield and explain that Tarka was working alone, and why. The 10-C turn off the DMA, sparing Earth and Ni’Var, and reveal that they saved Book. Discussing his grief and using his empathic abilities, Book convinces 10-C to stop using the DMA altogether, take down the hyperfield, and start working with others to make amends for the harm caused by the DMA. 10-C uses a wormhole to send Discovery to Earth, which decides to rejoin the Federation. Book is punished for his actions by being sent to help others who have been harmed by the DMA.
