Without giving many spoilers (that's why I drew them like featureless men), there is a quest near the end of Witcher III where I need to pick between 2 rivals.

Now, usually I like to look at the greater picture, their motivations, secret agendas and whatnot, but on this special case, when Geralt really needed, one of the guys was there for him. There was NO way I could just turn my back for him now. The other guy could be baby Jesus riding a pony and I'd sack him.
