but no for real
what if Dean gets back from Purgatory and when Sam asks where Cas is Dean just says
“He was there at the beginning but then he disappeared. He must have found a different way out.”
and Sam knows that’s bullshit because Cas would never leave Dean but he doesn’t pry
and then the flashbacks start
little scenes over the course of many episodes
we see that Cas didn’t leave Dean
of course he didn’t
they fought together
they survived together
they protected each other
and finally there comes a flashback scene that ends with the two if them huddled together in fear and despair, taking comfort from each other, and each looks into the other’s eyes, and it doesn’t even matter that it fades to black because we all know what happens next
next episode
last flashback
we find out that Cas sacrificed himself to get Dean out of Purgatory
Dean watched him die
he will never tell Sam
let Sam think that Cas might come back one day
the truth is Dean’s sadness to bear
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!
