"Survivors"
"Garibaldi's past catches up to him, with some disastrous consequences. He's blamed by some for an accident aboard B5, which leads to hitting the bottle again after a prolonged abstinence."
Another fairly standard sci-fi plot. A main character is accused of a crime they would never commit. What made this episode better was that Garibaldi failed. When times got too tough he went back to the bottle. And this would be a problem that would stick with him for the rest of the show. I really like that and I think that might be why Garibaldi is one of my favorite characters.
