Yay, you've watched it! It really is a firm favourite of mine, so I was looking forward to your comments even more so than usual.

I absolutely believe that G'Kar was capable of making the other decision in spite of angels and wise figures; I feel that it really was his choice.

What Kosh did was giving G'Kar a chance, providing a moment to step back and reflect on what he was doing. What G'Kar made of it is entirely G'Kar's decision, as you say. He could as easily - more easily in fact - have said "to hell with that, at least I'll take Londo down with me!", in the same spirit as he was in the elevator a few episodes earlier. Still, Kosh providing that chance is one of three lucky breaks G'Kar gets - the first being Morden not choosing him but Londo in s1. (Had Morden chosen s1 G'Kar, and given him what he wanted (reminder: all the Centauri dead and Narn children playing flute on their bones was the general idea), G'Kar's life would have gone a very different way.) What makes G'Kar's arc so great is that his epiphany doesn't mean G'Kar from this point onwards is just a saint, or that making the right decisions comes easily to him - realisation means nothing without follow up, and you have to get up each day and make that decision anew, work for it every day.

I kind of love Sheridan & Ivanova, ngl. I don't ship them at all but I love their relationship, because I am a sucker for mutual-respect subordinate relationships.

I think their relationship is great as well. To me, it also has overtones from a big brother/younger sister relationship - she teases him on occasion, he feels protective for her but not in a patronizing way, he knows she can handle herself. And in this case, he looks out for her soul as well as her career.

Bester is as always so much fun to watch.

Isn't he just? I'm soooooo glad JMS wrote this part for Walter Koenig to shine in. And the Bester/Garibaldi scenes are always a particular highlight, plus immensely quotable. Incidentally, this isn't Bester's last visit this season, he'll come back in another episode. Trivia alert: the female Psi Cop showing up at the very end of "Dust to Dust" (and earlier in the teaser scene of "A Run Through Dark Places" in s2) is Walter Koenig's real life wife. Here is a 2019 interview of Walter Koenig speaking about playing Bester and working on Babylon 5. (No spoilers, plus after 20 years he gets a few details wrong - Sinclair was a Commander, not a Captain, Bester was never the leader of Psi Corps, though he was a high level operative, that kind of thing, but that's understandable 20 years later and at his age.) In it he describes how he came to play the part, why that was so satisfying to him and what kind of working experience he had on the show, and it's lovely.
