Torulf spoiler alert:
After doing all three endings, I can see how a red-flag Tordork is and fascinated by how he can subtly control both Arvo and Lake without trying much.
It's a bit sad to see how he always chases to that "highest" point in every aspect of his life (jobs, places, emotions,...), always talks about traveling to places to feel better than everyone else, and he will run away when things get hard, serious or just bored.
These things also affect Arvo and Lake, like they feel they aren't good enough for him. Playing as Arvo just feel like a teenage boy in the community finally being loved by someone, especially someone older but not worked out. (I relate sm, but I'm glad that I'm over that phase now, lol).
Long story short, if I really think about it, Tordork is maybe about 50% of a bad person (lol), but actions have been made, so he's still a jerk anyways.
I hoped Arvo and Lake team up to start a revenge arc against Tordork. And I think the best outcome after D5 is just him being guilty and apologizing, but let's wait and see.
