By the time Amy was able to get up, she knew that Cass would be long gone. She racked her mind for what she could do, but came up blank after a few moments; realizing she was useless in her weakened state. She took a deep breath as she reached up to try and find a handle on the wall to pull herself up. She got onto her wobbly legs and whistled loudly.

In the distance there was a clicking of nails in the otherwise silence of the large building. A few moments later, the loud panting from a dog's lungs accompanied the clicking. Not even a second later, a shaggy red blob came bounding towards her, his long legs stretching out as he ran. Amy smiled at the dog's gleeful sprints towards her and leaned her hands on her knees.

"Come here, Redbeard," she called in a sweet sing-song voice. The dog skidded to a stop as he reached Amy and bounced up and down at the sight of her. Amy roughly patted his head which only excited the dog more. "Come on bud, let's go sit down." Amy sighed, her energy strained already. She staggered towards one of the wooden chairs and collapsed down into it. The dog put his head in her lap and she scratched him behind the ears while the heat from his breath warmed her stomach.

"You're back?!" Amy exclaimed as the two brothers walked through the top landing from the garage. She leaned back in her wooden chair while glancing upwards with a crooked smile. Redbeard barked wildly as the two made the climb down the stairs.

"Can you quiet this thing please?" Dean said bitterly as he reached the bottom of the stairs, Sam trailing slowly after him, his footsteps heavier than usual. It was at that moment that Amy saw what Sam had draped around his shoulders. An arm, attached to Castiel.

"Cass?" Amy called over the dogs barking. Right after she gave a sharp whistle, which calmed Redbeard and sent him sprinting towards her heel.

"Hello, Amy," he said in his regular hoarse voice that seemed a bit more strained than usual. She stood up from where she was sitting and crossed towards the bottom of the stairs.

"Geez, you look like hell," she commented as she helped hold up Castiel's other side which gained a guilty look from Dean as Sam thanked her with a sigh of relief. "Calm down, Dean, I'm an angel. Of course I'm stronger than you," she whispered to Dean as he passed.

"Well, that wasn't what I was worried about at all, but thanks for telling me," Dean retorted, his eyes rolling practically to the back of his skull as he trailed behind the three of them as they helped guide Cass to his room.

"So what was with all of the books?" Sam asked, referring to the table full of open books in the center of the library that were sprawled all around Amy.

"I'm in the Men of Letters Library, with a giant collection on everything big and bad out in the world and you expect me not to educate myself?" Amy said with a smile as the lights flickered above her head as she was walking. "That's happening more and more around me lately," she gestured upwards at the trail of blinking lights that followed her around.

"I could help you with that once I'm a little better. Some other things too," Cass volunteered, taking large breaths between every couple words, even though his physical effort was minimal. As it just consisted of tapping his feet lightly on the ground to help with the grunt work.

"Yeah Cass, you should probably keep helping yourself and get better before you help this newfound member of The God Squad," at those last of Dean's words Amy shot him an upset glare with pursed lips and narrowed eyes.

"Yeah, speaking of Amy, you look a lot better than the last time we saw you." Sam mentioned, glancing up and down at the girl who beamed back.

"Well a couple nights of Netflix, reading, and a well-stocked kitchen helped a lot, but I'm still a little weak," after a long sigh she added with an almost defeated voice, "and I still don't remember all too much."

"Do you remember anything new?" Cass asked. At Amy's little shake no he sighed and turned his head away, closing his eyes for a moment.

At that time, they reached Cass' room and Dean opened the door for them all. Sam and Amy dropped him onto his bed and he quickly laid back on the stiff bed, sending the blankets into a ripple effect.

"Alright, you need anything, just call," Dean explained and Cass nodded without a word. They all exited the angel's room and as they did so, Sam stumbled into Redbeard, who whimpered weakly.

"Oh, I'm sorry buddy," he said a little higher than normal as he turned around to scratch behind the dog's ears, so he quickly forgot about his small injury.

"Seriously, though, can we get rid of the dog?" Dean asked exasperated.

"NO!" Amy shouted adamantly, her voice suddenly harsh and her face stern. Dean leaned back, startled at the sudden ferocity coming out of this small 17 year old. He mouthed a silent 'OK' as they all continued walking once more.

"So, what happened out there?" Amy asked.

"Well, Cass went rogue, obviously, and so we got Rowena and found him attacking some poor woman and got her to do a counter-curse. She got away and then we got here. Not much else to tell," Dean explained shortly.

"Well alright then," at that point, they reached the library entrance, so she whistled for Redbeard to follow her as she went back in to look at the books once more.

"What've you been reading up on?" Sam asked, as he followed Amy. He looked over the pale fluttering pages from the AC. Amy sat on her knees on top of a chair, looking over all of the open books and the finished stack to her right and the to-do stack on her left.

"Umm, everything," she folded her arms in her lap as she turned to look at him.

"So, you mind if I quiz you a little bit," Sam asked, sitting down in a chair next to her, turning it to face Amy. At those words, Amy sat up straighter, her eyes narrowing. Dean looked up slightly, smirking a bit at the look of confidence on the young girls face.

"Bring it," she said evenly. Sam looked almost startled at her look of intimidation, but then smirked in almost the exact manner Dean had.

"Alright, lets start simple. How do you get rid of a ghost?"

"Salt and burn the bones."

"How do you kill a shapeshifter?"

"Silver bullet or blade or decapitation."

"What about demons?"

"Ruby's knife, The Colt, ingestion of salt sometimes, exorcisms, and a crap ton of other things like angels and God and Eve and stuff."

Sam leaned back in his chair, folding his arms, with a cocky look on his face, "Recite an exorcism."
Amy smirked, "Exorcizamus te omnis immundus spirtus omnis satanica potestas omnis incursion infernalis adversarii omnis congregation et secta diabolica ergo draco maledicte utt ecclisiam tuam secura tibi facias libertate servire te rogamus audi nos. Which would have been a challenging question if I haven't known how to do an exorcism for years now. The real challenge is saying it backwards. Which I can do also. Observe: now audi rogamus te servire libertate facias tibi secura tuam ecclisiam utt maldicte draco ergo diabolica secta et congregation omnis adversarii infernalis incursion omnis potestas satanica omnis spiritus immundus omnis te exorcizamus. I can also do an angels exorcism, but I will not for obvious reasons." She said that last part while gesturing to herself.

Both Sam and Dean were now leaning back in their chairs next to Amy (Dean had come and sat down next to her at about the 'draco' of the forward exorcism). Amy beamed at the utter looks of disbelief on their faces.

"So," Amy not so subtly led into what she wanted, "can I come on your guys' next hunt?"

"Wa- hold- hold up," Dean leaned forward, "When did this topic come up?"

"Amy, um, what I think he's trying to say is that you aren't ready to go out on a hunt I mean you don't look to be very strong," as soon as the words left Sam's mouth, he knew that he said something wrong.

"I have spent days pouring over these books and have all of heaven's power on my side and I'm not strong enough?" Sam looked towards Dean for help with pleading puppy dog eyes.

"Don't look at me," Dean leaned back in his chair as he watched this utterly hilarious scene unfold.

"I, umm, uh, uh, sure?" Sam stuttered and stumbled.

"Yes!"

"What?"

"Dean, it sounds like she's pretty well educated, and she is an angel." Sam reasoned against his brother. Dean was at a loss for words. He just grunted and got up from the table to go off to some corner of The Bunker.

"So, that's a yes?" Amy asked cautiously, leaning forwards in her chair with one arm scratching her dog behind the ears.

"I guess it is."
