While the whole "No one here is exactly what he appears" spiel of G'Kar's is a classic of the show for a good reason, my favorite exchange in this ep is between Bester and Sheridan after Ironheart is gone.

"That's a lie."

"Yes it is. What's your point?"

Bester's tagalong annoyed me--she was trying too hard to be sinister. Hello, you want to at least try to appear to be the good guys, you know--you're supposedly on the same side, remember? I know you're evil, honey, don't mean you gotta be stupid.
