Incredible. The build up of suspense and then the explosion of violence is very well executed (sorry, couldn't resist the pun). I suspect the rogue intended to submit but Jimmy's wolf was far beyond accepting. You've given us quite the cliffhanger but I'm going to speculate just a bit. The question for me is who was the other wolf? You've given us a number of hints that Sawyer is an unusual person. His affinity for night time runs in the woods and the sense of calm it brings. His preternatural senses i.e. smell and night vision and then there's his mother. Maddie's behavior with her little pack and dogs in general suggests she too may be something more. So my thought is that Maddie might be the child of an alpha that didn't turn and that she passed along enough werewolf dna to make it possible for Sawyer to be turned. That would also explain Jimmy being drawn to a "human" mate. I know you won't respond to my thoughts and I'm perfectly happy to wait and see where you take us.
Oh, I think Fergus is gonna spit nails when Jimmy shows up with a freshly turned wolf as his mate and dragging the carcass of the dead rogue.
