I absolutely despise spoilers. I've actually read comments from people who say they know not only how Season 4 will end, but how the series will end! Is this kind of information actually available out there?? (And for the life of me...WHY??!)
it's what everyone is saying here, there are guessing what will happen, that doesn't make it real. I read that Kripke doesn't know it yet himself, he's still choosing between names for the last episodes, so if Kripke doesn't know it yet, why would anyone else do!!
There is no information out there that tells anything about how the series will end however there is theories people have, but usually they don't end up accurate so don't pay any attention to them, unless your curious about others opinions. The information out there is out there to try to be spoliers.
Don't spend your valuable time reading it. Watch the eps and have fun! It's eventually gonna end, so, enjoy it while you can. Don't suffer before the time comes! Bless ya!
