PLOT TWIST: Dean is actually in a coma since s1/car-crash and the whole show is his imagination. EVERYBODY LIVES
And all characters that appeared after that are just people who work in hospital, like Castiel is a doctor/nurse, Kevin is med student or something and so on
It makes me sad that this hurts so much less than what is actually going on in the show right now
Go sit in the corner and think about what you’ve done.
