Dean raced in the Impala toward the large house where this all started, with every intention of killing the spirit. Upon arriving though, he soon remembered that not only was Ania a spirit, but a mythological spirit. She had also told him that they would never be able to kill her. So he settled on looking for answers on why Ania was doing what she was doing. The hunter screeched to a halt outside the house and stormed in. the door was still hanging off from when the boys kicked it in. After scoping out the house and finding no one there, Dean returned to the car and called his brother. When Sam answered, Dean heard the low groaning of Castiel in the background almost immediately.

"Hey. How's he holding up?"

"Not good. He's been getting some sleep, but when he's awake it's awful. He just"-

Sam was interrupted by a thud from the angel behind him. He swung round from his laptop to see Castiel laying on the floor, fists clenched until his knuckles were white, making an attempt to breathe through the pain without groaning. Needless to say he wasn't doing a very good job. Sam sat his phone on the table and knelt by his helpless friend.

"It's alright Cas. You're gonna be fine. Are you okay?"

The angel's attempt to push himself off the ground wasn't successful either. He moaned in pain once more and his arms gave way from underneath him.

"Hang in there Cas." Sam said supportively as he rested a hand on Castiel's shoulder, before returning to his phone call. "Yeah, he's not great. How's it going over there?"

"She bailed."

"What?"

"Yeah, she's not here. probably out torturing some other poor bastard. Listen I'm gonna wait here til' she gets back. You gonna be okay with Cas?"

Sam looked over to the angel once more, only to see him lying with his eyes closed, breathing shallowly. "Yeah, I should be fine."

Dean camped outside Ania's house in his car for most of the night. He had drifted off and awoke early the next morning to see Ania arriving home. Dean re-stormed into the house behind Ania, followed her down the hall and as she reached up to open the living room door, he pinned her hand to it with ruby's knife. He secretly hoped that Ania had been lying the entire time about them not being able to kill her, and that when he stabbed her he would cause her as much pain as she caused Castiel. However, she had not been lying. When he stabbed her hand, she did not bleed, or flinch with pain. The only thing the stab emitted from her was a snarky comment.

"… this is my good hand."

Dean pulled the knife from her and spun her round to pin her back against the door. Despite looking a little offended and angry, Ania continued the uncaring façade.

"Are you going to break every door in my house?"

"What have you got against Cas?"

"What haven't I got against him? He's the reason Greek mythology is a myth. Him and every other angel I can think of. They were created and we were wiped out of history, into another universe that you people call myths." Ania leaned in to whisper into Dean's ear.

"I am stronger than he ever was." Ania hissed "the angels ran us out of the universe, but your friend is pathetic. And he as the nerve to tell me to stop harming people! He's getting what he deserves."

Dean looked down at the girl he was faced with, into her piercing blue eyes and retorted.

"If you don't stop what you're doing, right now, I will do everything I can to make sure I waste you, until you don't even exist as a myth.."

"What I'm doing?" Ania replied "I'm not doing anything."

Dean grabbed the girl by the jacket, slamming her back into the door, his eyes filled with rage.

"Take it back! Now!"

"I'm not doing anything to your pretty-boy angel! I'm just fixing the situation to make it easier on my brothers."

"What?"

"Well since I've shown up, you've been chasing me, chasing all the trouble I've been causing everywhere I go, dragging yourselves away from your core problem, and giving me more time to…. Play, with your precious, broken partner. I've got the fun job. My brothers just want to make him squeal a little." Ania sneered with an evil grin.

And in the blink of an eye, she had disappeared into thin air once again. Dean raced back to the motel, where Castiel was. He lay sometimes in bed, sometimes on the floor from when he tried to get up but couldn't. Every so often he would let out a cry of pain, and Sam sat in the kitchen, unable to help at all, so he researched more about Ania and her brothers and how to stop them. He also looked up possible diagnoses for Castiel's symptoms: panic attacks; shortness of breath; weakness of arms and legs; extremely high temperature; extremely sharp pains in the head and stomach, and came up with a whole lot of nothing. Dean came charging angrily into the house not long after Cas had a short screaming fit from the burning pain in his head. He lay on the floor, pale and sweating when Dean came in and strode towards Sam.

"What have you got on how to kill this bitch? Seriously, there's got to be something. Everything can be killed."

"Well, there's the Kharites. They're the opposite numbers for Ania and her brothers, but like I said, that could start another war on earth that isn't our fight."

"You know what? I think it's worth the risk now. I mean, look at him." Dean said as they turned to face Castiel, who looked worse than ever. Sam gave a small nod in agreement.

"Alright then." Dean confirmed. "How do we find them?"

"Well that's a slight problem. The opposite numbers of these spirits tend to literally be the opposite. They won't be anywhere nearby."

"Crap."

"Yeah. But, we could always find a way to summon them, but we'd need to take some pretty extreme measures."

"Such as?"…

"It says here we need to… um, crush the bone of the Algea's victim in order to summon them here" the younger Winchester replied before glancing to the quivering angel, then back to his brother.

"Dude, he can barely stand up."

"You got any better ideas?"

Dean contemplated a total of two other ideas in his head, neither of which would be easy-going on Castiel, and agreed on summoning another mythological spirit.

"So who are we looking for?"

"Uh… one of three spirits. The Kharites, they're spirits of graces, beauties and favours. You sort of need to summon them all at once but who knows if they'll all turn up."

"Well, it's worth a shot." He concluded as he knelt by Castiel, who was once again drifting in and out of sleep. "This won't be fun buddy, but we're doing this to get rid of these sons of bitches. Okay?"

The angel merely winced in response, but the brothers took that as a signal to get started, and they got to work.
