Lucifer wasn't exactly wrong in his statement. If Dean had to watch Cas's body fuck his brother he was pretty sure his heart would break. Well...what's left of it anyway. It never fails to escape his notice that when he thinks he might be able to get a little better with his whole self-loathing thing something like this happens that makes him hate himself even more. He hates the way he gives in to the torment even if it's biting his tongue to keep a scathing comment back that would ensure he made good on his threat.

The noose around his neck was a surprise though. He clawed frantically at it when the devil tugged as his air was cut off. His face turned red, his eyes bulged slightly and he made a gasping strangling sound. Once it was released he gasped in a massive lung full of air and cough violently which aggravated his side something fierce and pulled a pained whine from him. He didn't move though, his mind a bit more occupied at the moment with replacing the oxygen it was deprived of.
