But in all cases, I need to make further assumptions, it isn't in my personal way of thinking to assume more than necessary in order to explain something. As people wanted to explain gravity and Newton discovered the laws of motion and gravity, there was no reason to make further assumptions. Gravity might also be explainable by other models, which are more complex models in return. Only later when Newton's theory reached its limits on electrodynamics, there was a reason to overhaul the theory. So when it comes to that scene in SPN, I simply don't look that deep for further explanations just to ensure the scene makes more sense. The simplest explanation is to take it literally - Dean can kill her with anything as long as he wants to kill her. The next best explanation would probably be, the writers messed up in some way (However you call it, Misinterpretation, Bad Writing, ...) which would force you to look deeper for explanations. I don't follow that path.
