Michael and Book Are Parting… But Not for Long
One of the more emotional fallouts of season four’s plot with the DMA was the anomaly’s destruction of the planet Kwejian—the homeworld of Cleveland “Book” Booker, played by David Ajala, the smuggler turned paramour of Captain Burnham over the course of Discovery’s third and fourth seasons. The loss of his home drove Book to surreptitiously betray Burnham and Starfleet to work with the rogue scientist Ruon Tarka, as they worked on a way to completely dissipate the DMA even after its true nature and extragalactic origins were discovered.
Booker saw the light by the end of the season, and nearly died in the process alongside Tarka, but after being saved by the Ten-C he turned himself over to the Federation to pay for siding with Tarka—pulling from Burnham’s side and from the home he’d made with her on Discovery, and assigned to community service, aiding Federation relief efforts on Europa for families impacted by the DMA’s fallout.
