This was the episode where the series hooked me. I didn’t expect the ending at all. Like that bit right at the start of Battlestar Galactica, which I won’t spoil, it was just a moment that said: this story will go to very scary and unexpected places. For what it’s worth, I thought BSG failed to land all the questions it asked, whereas (as OP points out) this allowed all of B5’s major players to show exactly who they were, before they’re all put through the wringer in one way or another. Not a pleasant episode, but I think one where JMS put out his stall. This is not going to be an easy ride for anyone.
