Oh, friend. 

It will get better, but only after it gets worse.  Londo and G’Kar - though particularly Londo - are not given the luxury of small mistakes or even just one large one.  But the way they emerge on the other side of those mistakes is what makes them the best characters on the show. These two change the most, period, of any characters on the show, and their growth is largely because of each other.

Even if you do not end up specifically in shipping Londo/G’Kar hell with me, I think it is very rare to come away from this show not really enchanted by and invested in their relationship, whatever it is.  Nearly everyone cites one or both of them as a favorite character from the show, and I see “Londo and G’Kar’s relationship was amazing!” in places that I usually only see dudebro whining, so it’s pretty spectacular.  

You have just begun the move into the dark of it, and it will get darker before there is really hopeful light.    Someday, at the end of Season 5, you will look back at Season’s 1 and 2 and be astonished they were ever that overdramatically hostile toward each other, just you wait.  You can do it~!
