Knowing there's going to be a shapeshifting villain in the game opens up a lot of potentially interesting situations, particularly some creepy ones involving the romance plotlines.
Imagine a scenario where you defeat one of the game's main bosses merely because The Dark Urge compelled you to murder one of your companion or lover that one time. I suppose having Orin and the Dark Urge connected might preclude that.
I'm also interested how some scenes will play out when you might already know someone you're talking to is really Orin.
Don't know if you know or how many on this forum would know. But I get the same vibes from Orin as I got from Morinth in Mass Effect. And there is a lot of potential here...like is Lae'zel even a real person? What it it's just Orin stalking the party...not likely but could theoretically happen. Or if you could create an alliance with Orin where she kills and replaces one of your companions and nobody else at camp is the wiser. There's a lot of potential for this to develop in all sorts of ways.
