"Of Blood and Salt" is far from over, i assure you!
However, there are two endings that could happen!!

I want you to decide which one YOU want!
Just put "Ending 1" or "Ending 2"

Here they areeeeeeeeeee:

Ending 1:
Good end. Dean and Cas have a baby, live happily, have a good life as mates for eternity.  Sam is also happy with a girl he has fallen for (sarah ;D). things are good, and we end with some dirty, fun wing!kink and a loving family
this is the happy ending full of fluff and joy


Ending 2:
Bad end. Cas is forced to kill Sam. In a blind fit of pain and anger, Dean kills Cas, who doesn't try to fight back because he loves Dean. Dean realizes what he's done too late, and cries over his dead brother and his lost love.
he either
>kills himself
>lives a long, miserable eternity doing his job as a crossroads demon. he is heartless and emotionless and he hates everything
this is the sad ending full of angst and pain
