what if dean is about to kill sam and then he resists and then we're like "phew, that was a close one" but then we hear a scream from dean and the screen goes black and we don't know what exactly happened
Well, that would be very evil of the writers, anon. Did Dean kill Sam? Did Sam kill Dean? Did a rat scurry across the floor , revealing Demon!Dean’s true weakness is his overwhelming fear of the small and furry? Did Sam take the opportunity of the dark to whisper sweet dirty nothings to his demon brother? We won’t know for WEEKS.
Cruelty, thy name is hiatus.
No but actually if they were to leave it on a cliffie like that I would explode and die. I don’t think they will, though. They’ll just sink us into a hideous dark pit of sorrow and pain for the summer.
