Kovich consults with Culber about Georgiou, revealing that individuals who jump both dimensions and through time suffer a physiological breakdown as every molecule tries to return to its own time and space.

Vance questions whether Burnham will be able to let Georgiou die or kill her if she becomes a danger based on her hesitation in the case of Airiam. Burnham assures him she will never hesitate again.

On Discovery, Saru, Tilly, Stamets, and Adira watch the video message from the captain, a Kelpian, of the ship that emitted the distress signal. The message is over a hundred years old and predates the Burn.

Georgiou steps through and finds herself aboard the Terran version of Discovery, being greeted by Captain Killy.
