Spoilers through 8.23. Warning for major character death.
Cas hesitated thirty seconds too long. A wheeze of “Kah-nuh-am-dar,” and the universe was shaken.
Cas, Dean, and Naomi arrived at the church to find Crowley sobbing, “Moose! MOOSE! SAM!!”
But Sam’s lifeless form lay sprawled at the foot of the altar. Dean ran to the body, felt for a pulse, and let his heartbreak spill from his eyes.
“Dean, I-” Cas began brokenly.
“I tried to tell you,” Naomi said softly. “I could-”
“No,” Dean choked. “He’s gone.”
Cas and Naomi looked at each other, and then Naomi manifested her sword. “Dean, I could use your help against Metatron. You and Sam.”
Dean looked at Cas. “Give Charlie the bunker key and the car. Tell Kevin I’m sorry.”
Cas nodded.
“Dean?” Crowley squeaked. “You’re not-”
“Save it, Crowley,” Dean interrupted, his words leaden.
Then he looked back at Naomi, and she sent him after his brother.
A/N:
jennytork and I were just talking about the mess of misunderstandings that characterize both canon and fandom as of the end of 9.13, and I noted that one point being missed by a lot of comments, including Sam's, is that Sam wasn't dead yet and that therefore Dean was going to do everything within his power to do his "one job," even if--as turned out to be the case--it meant doing something Sam would never condone. That got me thinking about what would have happened if Sam had been dead... and this was the result. (Let's not refight the question of who's [more] right and who's [more] wrong in the comments, 'k? Thanks.)
