He's the owner/operator of Quincannon Meat & Power, and he's got his stubby little fingers in almost every aspect of Annville, including a questionable past with Jesse's father.
Even the sheriff seems to do his bidding, as he quickly brushes off the murder of one of the prostitutes from Toadvine.
What we need to know:
Did Jesse just defeat the season one villain in one short scene? Where do we go (as far as big bads) next?
What's the history between Jesse and Quincannon, besides Jesse's father's land? What does it mean that Jesse can now control him with his gift? Will Donnie become more important to Quincannon, therefore more dangerous to Jesse?
