Holy crap, that was an excellent episode.
Answered a
lot of questions, like the whole B4 thing, Londo's future (and Vir's

), and the Minbari...
Okay, when I first watched "Babylon Squared", I assumed that B4 was being sent into the future to help out with the coming war. Of course, I was kinda wondering why they would need two Babylon stations so close to each other, but dismissed that thought. Of course, then comes Delenn explaining that it was actually send to the
past to the previous war.
Now onto the questions (which I know won't be answered

).
-Future Londo, he was infected with a parasite or something that was controlling his actions, right? And it looks like he had to take his last opportunity for redemption. And an interesting take on his vision of his death, with G'Kar's hands around his throat. And what's with Vir? Just because he picked up the Emperor's badge or whatever makes him the Emperor?
-What did Delenn see in her time flash (the before mentioned son?)?
-It seems like everything that happened in the episode happened for an explicit reason. The major thing I noticed was that the station jumping forward in order to off-load the B4 crew. Thing is, later on they said the Minbari wouldn't have accepted the station with a human on it. But there was no mention of what they were planning to do with the B4 crew before the accident/time-jump.
-Where did Sinclair manage to get two Vorlons for his little welcome speech to the Minbari?

(And he looks sorta cool as a Minbari.
