For years and years and years, I thought that
getting Boris and Olga back together was simply an amusing side-story, but not worth doing (because you don't get any points for doing so).
Now that I've done it as a paladin, I realised that doing this side-quest
gets you a whole bunch of Honor points (and, if you're lucky and your Honor score is high enough already, you can even get the ability to heal). Cool!
Anyway, I hope this helps those of you who haven't discovered it yet (or who have simply decided it wasn't worth doing, like me).
