Regardless on whatever the fate of this show might be, cancellation or renewal, I do have a few scenarios of my ideal ending for the series finale. Or rather how the last shot of the entire show should be, since everyone knows my ideal series finale battle: Apocalypse 2.0 that isn't anticlimactic, unsatisfactory or a huge disappointment like the last one had been, and worth everything that the show was built-up for. But in any case, for the end of the Winchesters story especially I have two specific scenarios on how I want them to go out:
( Carry on my wayward son, there will be peace when you are done... )As for the fate of Castiel, I see it happening in one of two ways. After the War in Heaven is eradicated, Castiel either goes back to Heaven but still watches over the Winchesters (in either Scenario #1 or Scenario #2) because he is still their friend after all, or Castiel decides to stay on Earth and carry out particular missions and retelling the story of the Winchester legacy. Or something to that effect. It's still being thought out on that one, but I definitely believe that Castiel will continue to be in contact with Dean and Sam no matter what happens.
Highly doubtful any of this will happen, since the show and I aren't communicating well these days. Nonetheless, this is how my ideal endgame for show plays out inside of my head, and that's how it should be done imo.
What are your thoughts or particular ideas for the series finale, oh dear flist? How would it go and what would it contain, perfect ending or bittersweet? Satisfactory or open-ended? I am genuinely curious on what other people think.
