From reading that, I can understand, why they did choose Alfira as the victim. She is widely liked and it is more shocking, than an NPC, that ask to stay for a night. The shock value would probably only be greater, if Durge would kill Scratch or the owlbear baby.
But I get, that it is annoying to loose a character with potential story that way.
I probably will stay away from playing a Durge for now.
