Yes! That broke my heart. Especially since he did get what he was so desperate to get - and then had to play the heavy with Sheridan, so Sheridan and Delenn believe that he granted only grudgingly what he begged and sacrificed for.

Past the ground-level nope nope nope fuck nope of Drakh control, so much of what makes it Londo's particular hell is that he had finally gotten out of playing that role—the doubling-down Londo of the Shadow War, throwing his weight around for the honor of Centauri Prime even when he knew that his beloved homeworld was in the wrong. And now he's forced back into it, not for the honor of his people, but for their survival, and it is the last way he wants to be especially with these people he loves. Peter Jurasik should have left this series with several Emmys before its final season, but just for his almost subcutaneous communication of a Londo who is no longer completely himself, just hand him another one and leave me to emotionally decompensate.

If nothing else, in that last scene with Londo and G'Kar in season three, G'Kar isn't surprised by the sight of the Keeper, so he clearly found out about it at some point between now and then. I just like to think it was on the slightly earlier rather than the endgame side of things.

My preference also.
