Don't own….

Bobby shooed Crowley off the property with threats of holy water shortly after that shocking announcement. Then he goes and finds the biggest bottle of whiskey he owns and three glasses. Dean and Sam gulp theirs down rapidly.

"This is fucked up," Dean says bluntly. "The King of Hell used to hang out with an angel." He pours himself another glass. "Isn't it bad enough Cas was conspiring with him behind our backs?"

"That was just a business arrangement, though," Sam points out. "It's just, you're saying Crowley was actual friends with an angel. As in, cared enough about him to miss him? Demons don't do that."

Bobby shrugs. "According to the book, yeah. Crowley and this one angel over in Britain stopped an Apocalypse a few decades back. The book ain't very detailed, but it seems there were no seals or vessels. Apparently, Hell put the Antichrist on earth to let Lucifer free. The Antichrist told good old Lucy to back off, and thought that was the end of it. From what I've gathered, Heaven and Hell both kept him in the dark last go-round, or things might have turned out differently. Crowley tried to approach him but, well, you seem to have seen the reason he couldn't get within the same country for long."

"Does the book say who the angel that tried to kill us was," Sam asks. "Or anything about how to beat him?"

Bobby reaches for a new bottle of whiskey. "The angel that tried to stop the Apocalypse with him. Seems Heaven really is not the Paradise it claims to be."

Dean shrugs. "It's not as if we didn't already know angels were douches. Of course he'd be fine with killing his friend."

Bobby shook his head, then drowned a glass of whiskey. "Heaven 'purged him of earthly attachments'. They believed he had been on planet for too long if he would willingly stand side by side to fight with a demon."

"That sounds...euphemistic," Sam ventures. "What did Heaven do to him?"

"The author doesn't know the exact details, or the terminology for most of the process," Bobby mused, flipping the book open. "From the sound of it, they injected foreign Grace into the rogue angel and combine it with…" He pours himself another drink. "Well, it can be described as lobotomy."

Sam and Dean exchanged looks, then reached for their own alcohol simultaneously.
