Looks like I'll have to reorganize my save files again, if every character is going to have 3-4 routes each. Ah, well.
Turns out I already had saves which lead directly into Dogtooth and Snouts, as well as one which was already at the mid-route ending where MC walks into the woods.
Looks like I may need to do another playthrough or two to find the third route that others are talking about, though. Not really sure where else in the story there could be potential diverging paths, I've already sided with Mikko, slept with (and not slept with) Torulf... what else is there?
