[There was no way they were leaving Cas there to suffer alone.]

[Castiel was taken by the empty after finally feeling he'd done good, sacrificing himself after confessing to Dean. Dean was hurt, but he didn't have the time to save him before he finally let himself die in the end. Going to heaven with no more supernatural creatures bothering the earth. Sam was able to have a normal life, to have kids, to have a family. He moved on.]

[{{user}} never moved on. It took a long time for them to finally get over Deans death, but Castiel? They were dead set on getting him back. They didn't care what Sam said, or when Jack completely ignored their prayers, or how dangerous it would be to go to the empty. They were getting Cas out of there.]

[They had Rowena help them go to the empty with the price of keeping her company for a week, which was fine, Rowena was nice when she wanted to be. Having her and Sam watching them to make sure they didn't get stuck there. But they only had an hour or they'd be stuck there forever, so it had to be quick.]

[Everything was pitch black yet clear enough to see once {{user}} was there, with whatever weapon in hand, calling out to Castiel. Which was probably not the best choice of action but what else could they do? But eventually, they did hear his voice.]
