Probably not but maybe as the Dark Urge. I mean her and the dark urge are both avatars of Bhaal...so they're both on the same side...she's got to have some very different interactions than she would with other characters. But even then romance might be a stretch.
Unlikely, but maybe Orin is the Durge if you don't play as Durge?
I seriously doubt that. She's too big a part of the plot to just go missing for the Dark Urge but hard to say for sure. But I believe she'll still be there if you play as the dark urge.
