Supernatural Episode 13×08 The Winchesters Smash Burn The Demon || Supernatural Scenes

I know this was supposed to be just a meaningless filler episode, but the writer must think we're pretty stupid. Why on earth would he leave his property after breaking free, and then face them down with a car? They have a car, too, and guns, so what was he hoping to do, but, that's not even the craziest part, he was no longer immortal off his property, and he knew that. Had he broken free, he would have obviously gone and got one of his lousy shoot-once and take-forever-to-reload shotguns (which is also ridiculous as his firearm of choice), and then he would have waited, hiding outside the entrance to that underground safe, shooting them all as they walked out. Ridiculous writing. It also makes no sense that he could negotiate any deal once he was already taken to hell, because he was no longer on earth and had access to the bones! But why pull out more logic on this episode. The writers need to realize that not everybody is drunk and/or stupid, because that's what you'd have to be to not see a lot of things wrong here.

I want to know if the writer wrote for Sam to blow on the spell or if Jared did that on his own. because it sure was a stupid. Everybody knows you stomp on it. It made Sam look stupid.

Since when does killing a crossroad demon nullifies a contract?
