Sam sighed heavily as he stood alone in the motel room. He walked over to the window but saw neither his brother or sister, wondering whether they'd gone off together or gone their separate ways. He leaned against the wall and dropped down it until he was sitting on the floor, elbows rested on his knees and face in his palms. He had no idea how he'd let things get this far. He never wanted this to happen, he just wanted things to go back to the way they were before. He picked up his phone and opened the contacts, his thumb hovering over the button highlighting Kate's name. She was too angry, she'd said goodbye to him. He scrolled up and stopped at Dean's name. He was angry too, but more upset with him. He sighed heavily and dropped the phone to the floor.

He sat there for a while, thinking over everything Dean and Kate had said to him before they'd left. His phone rang from the floor, pulling him from his thoughts. He glanced down at it and saw that it was Ruby. He stared at it until it stopped. Ruby was the core problem here, the one who was the main reason for the fighting going on between them. Maybe they were right, maybe he should just answer the phone and tell her where she could stick her plans for him. But then, she was the one who could help him get to Lilith, who could teach him what he needed to know and the one had what he needed to become strong enough to kill her. He needed to kill Lilith. After what she did to Dean. She dragged him to hell, almost killed both himself and Kate with the grief it caused them. She had to die, he just hoped someday Dean and Kate would be able to understand why he had to do this. He picked up the phone and called Ruby back.

Dean sat in the dark bar, bottle of beer and three shots of whiskey in front of him. He drank the shots before starting on the beer. He fumbled in his pocket for his phone, thinking about calling Kate and making sure that she was alright. He hadn't even bothered to wait around and see if she was coming with him or staying with Sam. He wanted to know where she was, but he also wanted to be alone for a while. Maybe he should call Sam. He considered giving him the ultimatum; sticking with him and their sister or staying with Ruby. He would have done it but right now, with wherever Sam's head was at, he was pretty sure they wouldn't be the ones Sam picked. And he couldn't take being told that by Sam.

Kate left the motel room and walked into the parking lot, noticing Dean's car had gone. She knew where he'd be, probably at the nearest bar, but she couldn't be bothered looking. She didn't want to talk to either him or Sam right now. She was tired of slugging it out with Sam, arguing over whether what he was doing was right or not. And tired of looking at the worry and pain in Dean's face. Watching him lie to her, saying that he was fine and everything was going to be alright. They all used to be so close, now it was like they were all just drifting further and further apart. She walked through the streets, not aiming anywhere specific, but stopped when she came to a bridge overlooking a river. She leaned against the railings and closed her eyes.

"You're not going to jump are you?" A voice asked from behind her. "Cause that would be dramatic."

"No, but I might throw you over." She muttered before turning around. "What the hell are you doing here Ruby?"

"Sam told me what happened." She stated simply.

"And? I suppose you care? Because you're the sweet little human demon that loves bunnies and chocolate cakes right?"

"No. I don't care about you. Or Dean." She practically spat out. "You know, I really don't like you Kate. And as for Dean, I despise the ground he walks on. But I do care about Sam."

"You care about him going dark side Ruby, there's a difference. You don't care about him at all so quit pretending."

"Don't give me that speech. You and Dean both bailed on Sam and you know it."

"Don't talk about what you don't understand." She replied coldly.

"Oh, I understand fine. You're a stupid little bitch Kate. You're following Dean around just like he followed daddy around. Don't you have a mind of your own?"

"Don't push me Ruby." Kate yelled.

"And Dean, he's just a coward. Your brother would've made a great demon. He's nothing more than a lying, vindictive, murdering little thug."

"Shut the hell up." She said, clenching her fists.

"I mean he goes on and on about Sam being all demonic or whatever the hell he says. But you should have seen him in hell, ripping those people apart. He was more of a monster than Sam could ever even dream of being. And you know what-"

She was cut off by Kate's fist crashing straight into her mouth. "You're nothing more than a lying little skank Ruby."

"A lying little skank who Sam loves." She smirked. "Either way I've got it better than you and your brother."

Kate punched her again and again until Ruby grabbed her hair and head butted her. She stumbled backwards and took a right hook to the face before standing up straight and punching Ruby in the face again. She punched her until she fell to the floor and went to grab the demon killing knife from her belt, her face falling when she realised that she didn't have it. Ruby grinned and stumbled to her feet with a laugh. She punched Kate again causing her to fall to the ground, hitting the head on the railing as she went down. Kate groaned as she felt the blood run down her face.

"What's the matter Kate? Your little plan to kill me with my own knife fail?"

"Go to hell."

"You really are a stupid little whore aren't you? You don't fight a demon without a weapon."

"Exorcizamus te, omnis immundus spiritus omnis satanica potestas, omnis incursio infernalis adversarii, omnis legio-" Ruby cut her off with a hard kick to the ribs.

"Shut up."

"Omnis congregatio et secta diabolica-" She kicked her in the ribs again, harder.

"It's not going to happen Kate." Ruby spat out, punching her a few more times in the face before knocking her out. She stood up and walked away, leaving her unconscious on the side of the road.

When Dean arrived back to the motel room it was empty. He turned on the light and immediately noticed that Sam's stuff was gone. He shook his head to himself and pulled out his phone, dialing Kate's number. A wave of panic ran through him when she didn't answer. He called her again and again until the fifth time the phone was answered. "Hello?" The voice wasn't Kate's. It was a guy, he sounded scared.

Dean immediately tensed. "Who the hell are you?"

"Um.. My name's Jake."

"Where'd you get the phone, Jake?" Dean practically growled down the phone.

"This chick, she's like lying in on the road. I think she was hit by a car."

"What?" Dean walked straight to the motel door and over to his car.

"I was driving past, she's just lying here. There's blood."

"Where are you?"

"The bridge that goes out of town. I should go, I need to call an ambulance."

"I'm on my way. Just, don't do anything until I get there. Don't call anyone."

"But-"

"No buts." Dean cut him off. "Just do what I'm telling you."

He arrived at the scene within five minutes. There was a car pulled over on the side of the road and a guy crouched down, a girl lying in front of him. "Oh god no." He muttered to himself as he ran towards them, dropping to his knees beside Kate. He took his sister's face in his hands and looked her over. There was deep gash on her forehead, blood trailed down one of her cheeks. Her left eye was already swelling and she had a busted nose and lip, as well as small cuts on her forehead and cheek. He gently placed a hand to her neck and released a breath when he felt her pulse. "Hey, hey Kate.. Can you hear me sis? Come on, just open your eyes for me." He shook her gently. "Please."

"Man, she needs a hospital." The guy who Dean had forgotten was sitting beside him said.

"No." He couldn't take her to the hospital again. He couldn't stand to see her lying in one of those beds again like the last time. "She's alright. She's just knocked out.. She's gonna be okay."

Her head moved to the side as her eyes slowly opened. "Dean?" She murmured.

"Yeah, it's okay, you're fine. I'm gonna take you home okay?" He noticed her scrunch her face up in pain as he picked her up and placed her into the Impala. He closed the door and turned his attention to the guy who was still standing by his car. "Hey, thanks man. You know, for staying with her and stuff." He grabbed a twenty out of his back pocket and handed it to him.

"You don't have to give me anything."

"Just take it, I've had enough arguments for tonight man." Dean smiled lightly.

"Well, thanks. Hope she feels better." He said, handing him Kate's phone and turning to get into his own car.

When Dean pulled up outside the motel, Kate had pretty much come around. "You think you can walk to the room?" Dean asked her softly.

"Yeah, I'm fine." She mumbled, ignoring the splitting headache and sharp pains in her ribs as she slammed the door closed and crossed the parking lot to their room, stopping at the door when she realised that it was locked. "So he's gone?" She asked Dean as he pulled out the key to unlock the door.

"Yeah, I guess so." He didn't miss the look of pain flash over her face for a second before she got herself under control again. He pushed open the door and followed her inside. "C'mon, sit down." He said gently, pushing her to one of the chairs at the small table and pulling out the first aid kit to begin cleaning the blood from her face. "So what happened?"

"I ran into a car." She said blankly.

"Don't give me that crap." He grabbed her hand and turned it over, showing the blood staining her knuckles. "You were fighting with someone Kate, so you might as well tell me who it was."

She sighed. "It was Ruby. She showed up mouthing off and I lost my temper."

"Did you kill her?" His voice was almost hopeful.

"No. I tried to exorcise her but she seemed to think it'd be more fun to knock me out." She muttered sarcastically.

"What did she say?"

Kate thought back to their fight, one line sticking out in her mind. Your brother would've made a great demon. "Nothing.. Just the usual stuff."

Dean narrowed his eyes at her. "Such as?"

"She made some smartass comments about Sam. Called me a few names, called you a few names. Ya know, nothing special."

"Right." He finished cleaning her face and went to get them a beer from the small fridge. "We'll find them Kate. We'll hunt them down and we'll stop Sam and then we're going to put a knife through her neck." She could tell by his tone that he wasn't kidding around, and she believed him. Well, she believed he'd try. But they both knew that it wasn't going to be anywhere near as easy as that.

When Dean woke up the next morning, his sister was still sleeping. He looked over her face sadly. She had a nasty black eye and a deep gash on her forehead, as well as a few other cuts, but other than that she looked fine. "Hey! Get up!" He said as he climbed out of his own bed. She didn't respond to him. Dean shook his head and poked her in the shoulder. "Kate, don't make me drag you out of bed with your ankles again." She mumbled something that he didn't understand and continued to ignore him. "Fine, have it your way." He smirked as he pulled the covers totally off her, the smirk quickly fading from his face. Her shirt was raised slightly at one side, showing the huge bruises on her stomach. "Kate, what the hell?"

She opened one of her eyes and looked up at him. "What's your problem now?" She followed his eyes to her stomach and saw the bruise, quickly pulling her shirt back down to her waist.

"Did she do that to you?"

Kate climbed out of bed and ran a hand over her face. "Yeah." She answered flatly.

"And you didn't think to mention last night that she tried to kick a hole through your ribs?"

"It's not a big deal, I'm fine. Really."

"I really am going to kill her."

She nodded. "We've gotta find them first Dean."

"Yes, we do. So how do we do that? And stop the world from ending at the same time?"

"I don't know. I mean, what are even supposed to do when we find them?"

"We take the knife, we stick it through Ruby's neck and then we kill Lilith the way we were taught to kill demons."

"Maybe we should call Cas? See if he knows where they are?"

"Worth a shot I suppose." He closed his eyes. "Hey Castiel, can you come down here please? We need your help."

Within seconds, he was standing in the room with them. "What happened to your face?" He asked Kate.

"Bitch happened to her face." Dean answered angrily.

Castiel looked at Kate and frowned. "Ruby."

"I see. So what do you need?"

"We need to find her. And Sam." Dean said.

Castiel vanished from sight for a few seconds before appearing behind them. He picked up a piece of paper from the table and wrote something down on it, handing it to Kate. "He's at that address. Good luck." With that, he vanished again.
