Hm.
There is a secondary path if you choosed Logan, but you'll still develop your relationship with him.
About Ste's plotline (the Minotaur), what exactly you're having problems with?
I remeber you need to talk to Logan and then visit the Path between the bridge and the Bandit's camp. Everyday something different will happen there.
(I strongly recommend you to go prepared because you won't have the chance to do it again. Depending on your actions, you may achieve the good or the bad ending of this event)
