Ain't No Rest for the Wicked
The night Clara delivered her kid, it was horrible; it was like the angels falling from Heaven again, but this was worst. They didn't lose their grace, they died. They were no match for Clara and now, her kid. Hell was more powerful than Heaven and the angels were losing hope if they haven't lost it already.
They also lost faith in Castiel and he was suffering. He lost his home and his kin; he had only his friends the Winchesters. At first, he was pretty depressed, but he soon helped them out on hunts and focused his attention on helping those in need. Although God wasn't around, he seemed to have found a mission: keep them believing in God even though he didn't. At least, that's what the Winchesters were certain of.
Now, two years have passed and Hell hasn't been a threat. No one's seen or heard Team Raise Hell, as Dean coined them. Crowley hasn't popped up to harass them, Clara hasn't come to wreak havoc, their kid hasn't made an appearance yet and Nikolai wasn't going around giving into his killer desires for blood with the Mark of Cain.
For the past two years, things have been eerily silent. Although the Winchesters were enjoying the lack of Hell activity and relaxing in their Men of Letters bunker, they were certain chaos would start up sooner or later. It was just a matter of time.
Not only was Hell quiet, but so were the Cromwells. They haven't heard anything about them until a few days ago.
A fellow hunter who claimed to have been saved by Bobby Singer a couple of times had called to ask for a little bit of help in regards of resources. Sam was nice enough to offer some, but Dean was just blunt and told him to quit hunting while he was still alive.
Before hanging up, the guy asked if they heard about this place that was like Hunters 'R Us. He wasn't sure about it and he'd like to check it out, if only the owner wasn't a witch.
That grabbed the attention of the brothers and they asked him for more information. Was the guy just politely saying she was a bitch? Either way, it was worth digging into.
Well, apparently it's a bookstore filled with all the equipment hunters could ever want and need. It's a hunter's one stop shop. You name it, she's got it. From guns and exorcism manuscripts to a junk yard filled with rundown cars at the edge of town. She's also got all your magical needs at her fingertips.
No, the guy really wasn't trying to say she was a bitch; he really meant a witch.
The guy wondered if she was really helping hunters or if she was some sort of neutral zone in the supernatural world. Witches can't be trusted with their spells and their cauldrons.
And that's when Sam suddenly could no longer tolerate the guy.
"What's her name?" Sam had asked and the guy couldn't remember. He tried, but nothing was making sense. Dean, who already lost his patience with this guy made a suggestion just put things into motion.
"Anne Cromwell?"
"Yeah, that's it!" the guy has said and then had gone silent for a couple of seconds. "How did you know?" Dean rolled his eyes and turned away or he'd refer back to his first comment. The guy really wasn't cut out for being a hunter. He was eventually going to get himself killed.
Sam got the address from the guy and both brothers were thinking the same thing: they could finally figure out what went on that night at The Devil's Alley by checking in on Anne.
They never found out what deal she made with Crowley. She got her mother back, but at what price? They tried to find out, but Gadreel had been worst than a bulldog. There was nothing they could have done and now, two years later, she had her own store where she was helping hunters.
Was it her way of fixing her mistake before she dies?
Then, like Castiel reminded them, Gadreel would never let her risk her life. She meant more to him than Heaven. If she made a deal with Crowley, it wasn't for her soul. So what then? What did she have that Crowley had wanted?
Once they found out that Clara was pregnant, the only thing they could think of was the fact that Anne was a Wiccan with some spells up her sleeve. Did Crowley want a spell from her? For what reason? And that's only if they were on the right track.
"I don't think she'll like getting a visit from us." Sam said, remembering how she acted the last time they saw her. She wanted nothing to do with them. He couldn't blame her. Her mother died and she went to them for help, only to find out that they only cared about all the souls that couldn't get into Heaven and that were later snatched up by Hell.
"Well, we'll just be passing through." Dean said and Castiel tilted his head as if slightly disappointed that his friend couldn't trust that the Cromwells were fine. "So, we leave tonight." He added and the brothers went to pack their things, leaving Castiel to stand in place, looking at the table where that paper containing her address lingered.
His friend Gadreel had no difficulty letting go of his grace. He had found a reason to live as a human. Did he miss his grace? Heaven?
But it's different when you chose to leave Heaven, unlike being cast out of it. And if Castiel decided to relinquish his grace, what would be his reason to live as a human? He could barely find one as an angel. Helping the humans was as good as any, but he still felt like something was missing.
Then again, perhaps it was always missing...
