Its fine if we disagree. Its just my opinion. I know how I feel about stuff like this, and I doubt anything will change my mind. To be clear, I'm sure I'll still enjoy B5. But, there is nothing that can effect Londo whatsoever from now on. I don't care about how he got there at this point. I wanted to see
where he was going. If I was rewatching a series, this wouldn't be an issue (I'd already know everything), but as a first time viewer I now have no reason outside my own enjoyment of Londo as a character to pay any attention to him ever again.
