From "Babylon 5: And All My Dreams, Torn Asunder (#5.16)"
[G'Kar tells Delenn that he plans to accompany Londo to Centauri and act as Bodyguard again
Have you told him this yet?
No, I was thinking of making it a surprise. I even booked the seat right next to his. It will give me someone to talk to during the flight.
Londo once told me he hates it when people talk to him on long flights. He prefers to sleep.
