“Do you really think that it’s possible to bring Cas back?” Sam asks in that tone that Dean hates because it means that his brother isn’t fully on board with something. “Jack didn’t really think that it could be done.”
“I don’t care,” Dean says, looking at his brother with determination. “I’ll bring him back home. I’m not gonna let Cas rot in the Empty. I’ll find him and I’ll bring him home. He deserves to be saved. He deserves to be alive.”
