This takes place from January 19 to January 20, 2261.
When Emperor Cartagia brings Londo into his chamber where he has the heads of dead Centauri on his desk, the head that is closest to Londo during the scene is a cast of Andreas Katsulas.
The line in which Emperor Cartagia offers Londo a bowl saying, "snicks?" after explaining how he plans to let Centauri Prime be destroyed was improvised by Wortham Krimmer.
