Garibaldi and Sheridan have two arguments, Sheridan and Delenn have a very public night of passion, and Cole and Franklin have a hard time dealing with the Mars Resistance. The Babylon 5 Rewatch stars “Racing Mars.”

An excerpt:

I find myself wondering what the plan was for Garibaldi’s betrayal before Michael O’Hare had to leave the show. The Sinclair-Garibaldi friendship was a cornerstone of the first season—indeed, Garibaldi only had his job because the commander was his drinking buddy—and having Garibaldi betray the station would have had much more weight if it was Sinclair he was betraying. But the advantage of it being Sheridan is that the relationship between the two of them was never particularly strong. Yes, they worked together, and generally trusted each other, but the closeness that Garibaldi had with Sinclair has never been there with Sheridan. And so Garibaldi’s turning on him actually has a certain sincerity to it that it wouldn’t have had with Sinclair.

Of course, it’s a bit spoiled by the fact that we know that Garibaldi’s being controlled by something or someone. It might have been more effective if we didn’t know that about him, and thought this might be a legitimate character choice.
