Plotline
Approaching the hyperfield, Discovery finds a dead planet. Burnham suggests a visit to the planet in the hopes of finding information about Species 10-C. Earth General Diatta Ndoye believes this diversion is a waste of time, but other diplomats support the idea.
Burnham, Saru, Culber, and Detmer travel to the planet where they find huge skeletons of a species that once lived in the planet's former gas layers. They also begin to experience hallucinations that create strong feelings such as fear. The team deduce that 10-C fled the planet during meteor strikes that burned away the gas and killed members of the species.
They eventually work out that the species use complex hydrocarbon compounds to communicate their emotions and that these are what is now affecting them on the planet. They believe they can use these hydrocarbons to help communicate with species 10-C.
Meanwhile, Book and Tarka follow Discovery to the planet and sneak onboard the ship. Tarka bypasses Zora's sensors to allow their ship to be attached undetected to Discovery's outer shell. He takes engineer Jett Reno hostage in the process. Book convinces Ndoye to help them destroy the DMA.
