Mark is planning to visit Maggie in prison for a conjugal visit but is interrupted when India launches a rocket that appears to use stolen US technology. 

Suspecting there is a spy, Mark organizes a search to find potential leaks within the Space Force.  He organized the search plan.

After determining that Chan, Kelly, and Bobby are not spies, he suspects that Adrian is the spy after finding he had sent an encrypted e-mail. 

Mark publicly decrypts the file to find a video that Adrian had sent to Jerome, one of the lunar habitat participants, to express his love.

Mark receives a call from the Secretary of Defense, who explains there was no spy, and India had developed the technology on its own.
