Help, I don't know how to get to Klaus' route, it's very complicated, any clue on how to get there?
You have to act like you're going to pursue Devon. Sit with lake, talk to rune and Devon. Make sure you get his coat, otherwise you can't get Klaus's route. You keep pursuing Klaus, his room won't be an option. You go with Devon, but choose not to help him that's how you unlock Klaus! (I just spent an hour trying to figure it out again, you can do bjorn too but it's a bit harder)
