Book mourns the loss of his homeworld and his family. In this situation, Burnham is delighted that Saru returns from Kaminar, ready to serve as her first officer. After a briefing at Starfleet Headquarters, the Discovery departs to investigate the anomaly that destroyed Kwejian. As the rest of the crew prepares the mission, Culber presents Gray's new body to Adira (and to Gray who is in their mind). While the ship has to remain at a safe distance, the only way to record data from within the phenomenon is to send Book's ship. Book insists on piloting himself, but a remote-controlled hologram of Stamets is to accompany him, to collect the data and to watch over him. During the mission, gravitational waves begin to hit the Discovery, causing a temporary loss of artificial gravity. Adira identifies the pattern, so the occurrences can be predicted. Since Stamets needs more data and the Discovery is taking heavy damage, the tether that connects the ships is released. However, as the engines of Book's ship are losing power, he can't return on his own. Moreover, he is plagued by hallucinations of his dead nephew Leto. Bryce comes up with the idea that he could surf one of the gravitational waves. Book escapes from the anomaly, and brings loads of data that Stamets considers very valuable. There is disturbing news about the anomaly, however: It has unpredictably changed its course.
