Specific fic: Dean gets out of Purgatory
Hi Everyone! I'm looking for a specific fic. Sam rescues Dean from Purgatory, but Cas is still there. Dean needs to get Cas out of Purgatory, and I think he is unable to function until he does. Maybe it was Destiel, but I can't really remember? I think there was a scene where Sam walked in on Dean performing a ritual. Wish I could give more info. Any help is greatly appreciated!!!!
