Plotline
Tarka begins dismantling Species 10-C's power source, causing dangerous plasma bursts to erupt from it.
T'Rina learns that the minds of Species 10-C are connected and they do not understand that individuals can act alone. The crew uses the spore drive to escape the orb, destroying the drive in the process, but are unable to approach Book's ship due to the plasma bursts. Ndoye offers to atone for her actions by ramming Book's ship with a shuttlecraft, killing Tarka. T'Rina agrees the plan and it is put into action. Just as Book's ship is destroyed, Book, Ndoye and Reno are beamed to safety, but Book goes missing in transit.
The crew of Discovery meet members of Species 10-C on a planet inside the hyperfield and explain that Tarka was working alone. Species 10-C agree to turn off the DMA, sparing Earth and Ni'Var. They also reveal that they saved Book. Discussing his grief and using his empathic abilities, Book convinces Species 10-C to stop using the DMA altogether. They agree to take down the hyperfield and start working with others to make amends for the harm caused by the DMA. Species 10-C uses a wormhole to send Discovery to Earth, which agrees to rejoin the Federation.
Book is punished for his actions by being sent to help others who have been harmed by the DMA.
