What is it with Babylon 5? IIRC that's the *seventh* major cast member from that series who's died, whereas Star Trek: TNG and DS9 (which were both around the same time) have had *one* of theirs die (Rene Auberjonois passed last year). Anyway, very sad news--I can still remember her announcement to the ships who were trying to take Babylon 5 for President Clark:
"Negative, ma'am, this is our juridisdiction. Do not force us to engage your ship."
"Why not? Only one human captain has ever survived an encounter with a Minbari fleet. He is behind me. You are in front of me. If you value your lives--be somewhere else."
