You've won the three rounds of killing, taking Paul's advice and killing the last dude with Paul's knife. Where all the other demons didn't seem to notice and were happy about it, Dean seems to be suspicious and angry now. What happens now?
Sorry it took so long to publish this. There's not many ways you can die in this round. This is more to progress the story. If you haven't played the other games in the series this might confuse you. Enjoy!
