Yeah, I think we went over that in TheGodBen's review thread, it would go something like this:
"What do you want?"
"To serve the Founders...in all things".
Then they stare at each other for five minutes with smarmy, slightly creepy smiles on their faces.
Then they part on "friendly" terms, each knowing the other has decided that they and everything they stand for must be destroyed.
I'd like Londo and Dukat to meet. They seemed to be on opposite trajectories. Dukat starts out pretty "evil" but kind of has a redemption arc, only to take a downward spiral to eventually become almost Satanic. Londo starts out friendly and boisterious, more of a comic relief character, gets much darker, and eventually becomes an almost tragic ... when, maybe not hero, but certainly not a bad guy.
I dunno, I suppose in a way though Dukat could be more like Cartagia ...
