B5, "Convictions", S0302

Season three has started off pretty awesome. The second episode so far is a standalone, dealing with a mad bomber terrorizing the station.

Best part: G'Kar and Londo, stuck in a slowly burning elevator (damaged by a bomb). G'Kar refuses to help Londo and he escape, for the reason that he'd rather see Londo dead that he survive. Scene ends:

Londo: "This insane! Can anyone out there hear me!"
G'Kar: (raising his hand, and in a tiny voice, holding back his laughter, next to Londo in the elevator) "I can hear you!"
