- Kovich: Now, I understand she's been presenting with physiological symptoms, but the cure won't be found anywhere in this room. Or in this galaxy, for that matter. Computer, open classified file Beta-4895-Omega. Lieutenant Commander Yor. Deceased. Time soldier.
- Dr. Hugh Culber: Time soldier?
- Kovich: Consider yourself lucky to have skipped the Temporal Wars. Amongst the many horrible things we discovered when weaponizing time: temporal travel can make you pretty sick. Turns out our molecules are designed to function in the time in which they're created.
- Dr. Hugh Culber: But everyone on Discovery traveled through time.
- Kovich: Yes, but only one of you is also from a parallel universe. Yor here traveled forward from 2379 and across from an alternate universe created by the temporal incursion of a Romulan mining ship. Before Georgiou, Yor was the only individual known to have traveled across both time and dimensions.
- Dr. Hugh Culber: So, you knew this would happen to her?
- Kovich: Suspected. Every molecule fights to either go back in time or jump a cosmic divide. By the end, Yor was in such pain the doctors petitioned the Federation for euthanasia.
- Dr. Hugh Culber: They couldn't send him back to his own universe?
- Kovich: Not without breaking the Inter-dimensional Displacement Restriction. Part of the Temporal Accords. Which are ironclad.
- Dr. Hugh Culber: But Georgiou didn't get sick when she first crossed to the Prime universe.
- Kovich: 900 years have passed. The Prime and Mirror universes have been drifting apart the whole time. Yor's experience was a breeze compared with what Georgiou is about to face.
