Sam stood in front of the demon with Ruby standing beside him. Sam wiped his mouth making sure that there was no left over demon blood on his mouth. He walked over to the demon and pulled off the bag around its head. He looked at the man and saw the way the man looked at him.

"Well, if it isn't Sammy Winchester," the demon said laughing.

"Shut up," Sam said.

"Why? I mean your little insurance policy isn't here. Where is the lovely Katerina tonight? She leave you high and dry now that your brother is back in the picture?"

Sam tried really hard to control his anger. He looked at the demon and saw the smug smile on his face. He shook his head and turned around walking off to the side. He took slow deep breaths like Kat had told him to do when his anger got out of hand. He turned and looked at Ruby when she walked over to him. He shook his head when she went to open her mouth. He really didn't want to hear what she had to say. He really couldn't care less about what shit she was going to say to him about not letting the demon get to him. He looked back to the demon and wondered how many other demons thought the same thing this one did. That Kat and him had been an item. He turned when the door to the warehouse opened and Kat walked in.

"There she is! The real power behind the Winchesters!" the demon yelled at seeing Kat.

"Go to hell," Kat ordered smirking when black smoke bellowed out of the demon's mouth and filtered to the floor disappearing in flames and more smoke.

"Thanks, Kat, really. Sam was supposed to use him to practice!" Ruby stated looking at the guy looking around confused as to why he was there.

"How about he practices on you?" Kat asked walking over to them.

"Enough, both of you," Sam said not being able to deal with the two of them fighting.

"Whatever. I'll get the guy to the hospital and look for another one for you to practice," Ruby muttered walking by. Kat grabbed her arm and yanked her close.

"Sam isn't practicing with you tonight or any other night. Disappear Ruby by your own choice, or I will make you disappear."

"I'd like to see you try."

Kat looked into Ruby's eyes willing her hand to heat up. She saw Ruby's eyes go black. She grabbed Ruby's other arm as it came up to hit her. She glared at her and smiled softly. She felt Sam hovering over her and knew that he was ready at any moment to step in between them if anything happened. She looked deep into Ruby's black eyes and didn't feel fear. Instead she felt anger and hate towards this evil thing that had pulled Sam into her evil web. Kat wanted nothing more than to send her back to Hell or even kill her.

"I will kill you Ruby. I promise you that it will be the most painful experience you will ever experience in your life. Now get the hell out of here and do not come back and darken Sam's door again or I promise you, there will be hell to pay," Kat said shoving Ruby aside.

Ruby stepped forward to go after Kat but Sam stepped in between them. He gave Ruby a look and Ruby turned and walked over to the man. She helped him up then carried him over to the door and left. Sam turned to look at Kat. He never saw the punch coming and it landed on his cheek. Pain exploded in his cheek and lower jaw. He turned and looked at her and saw the tears forming in her eyes and knew that something had happened between her and Dean when he had left. He really hoped that it hadn't been another fight between them. He feared that this time that it had been about him.

"Kat-."

"Don't. Just, don't. This," Kat said waving her arms around the room to indicate what he had been doing with Ruby, "needs to stop. NOW."

Kat watched as Sam turned away from her. She shook her head and looked at her watch. She really didn't know how much time she had before Dean came back and Castiel sent him this way. She just hoped it was enough time so that she could convince Sam to stop what he was doing. If she couldn't she would have to take the next step. And the next step was going to be tough for all of them to handle.

Dean watched his father as John checked out the vehicles on the lot of the used car dealership. He shook his head still shocked that he was here and watching his father. Everything about his dad was carefree and happy. It was like John Winchester was an entire different person. Dean walked over and leaned against the impala as his dad looked at talked to the salesman about a Volkswagen van. Dean couldn't let his father buy that. There was no way in hell that Dean was going to drive a hippy van around. He waited and watched as the salesman walked away. He went over to John then.

"That's not the one you want," he said softly.

"Oh, really?" John asked looking up and seeing the guy from the restaurant. He stood up and watched as the guy tapped the '67 impala on the hood. John looked at the car and instantly fell in love.

"This is the car you want," the guy said moving aside so that John could look at the motor. John listened as the guy rattled off all of the stats for the car and knew in his heart that this was the car he should be driving off the lot. He turned and looked back at the hippy van and remembered the promise that he had Mary. As much as he wanted this car, he loved Mary and he wanted to see her happy which meant that he was going to be driving off the lot in a hippy van instead of this awesome car.

"You're right, this car is awesome," he admitted.

"Then why are you buying that van?" the guy asked and John watched as the stranger turned and looked at the van. In that moment, the stranger reminded him of Mary. He had seen Mary look at something she found distasteful in the same way that this stranger was. It was weird. It was like this guy was related to Mary or something. John pushed those feeling aside as the stranger turned and faced him again.

"I kind of promised someone I would," John said smiling slightly when he thought of Mary.

"Over a 1967 Chevy impala? Wow, must be someone special," the stranger said.

"Yeah, she is. John Winchester," John said holding out his hand.

"Dean... Van Halen. I just... I wanted to thank you for buying me a coffee back there," Dean said knowing that he couldn't say his real name without freaking his father out.

"You're welcome. You seemed pretty out of it back there.

"I was. I just... I guess I had one wild night."

"That you did."

"Did you notice...? Well... The cold spots back there?"

"Cold spots?"

Dean watched as John turned to look at him and gave him a weird look. Dean took a deep breath and tried to figure out how he could go about asking about anything supernatural without scaring his dad. Castiel had said that he had to stop something. To Dean that meant that he had to stop something supernatural and he didn't know how he was going to figure out what he was suppose to stop. He looked down and tried to put together a plan that might help him figure out what was going on. He knew whatever it was had something to do with his parents.

"Yeah, cold spots. Did you notice them back there?" Dean pushed.

"No, I didn't."

"What about any cattle mutilations or-."

"Sir, I really don't know what you want but just stop."

Dean looked at John and nodded, "Sorry, man. I'll just leave you alone."

Dean walked away shoving his hands in his jacket pocket. He walked around the corner and found an old car. He looked around and noticed that no one was watching him. He tried the door handle and found that it was unlocked. He climbed in the car and flipped down the visor. He smiled as the keys fell into his lap. He shook his head a little as he started the car at how careless some people could be. He turned the car onto the street. He parked across from the car dealership and waited for his dad to leave. Once he did he would follow him. He needed to keep an eye on his dad because he had this sinking feeling that what he was supposed to stop had to do with his parents.

As he sat and waited his thoughts turned to Kat and Addie. He wondered how they were doing and if Kat was worried about him. If he knew his girl, he knew that she would be worried and angry at Cas for letting Dean do this alone. He smiled a little when he thought about how much his life had changed since meeting her. He was ready to commit to her and to make her his everything. Hell, she already was his everything. Her powers scared him, sure but if he was honest to himself deep down he trusted her to make the right decisions about her powers. He just worried about her putting herself in danger because she thought she was invincible because of her powers. He pushed all thoughts of his lover and their daughter aside as he saw John drive off the lot in the impala. He smiled a little and followed his father down the street. Hopefully, his father would lead him to his mother and he could figure out what he needed to stop.

Kat paced in front of Sam and waited for him to tell her the reasons why he was so unwilling to stop what he was doing. She stopped pacing and looked at him leaning against the wall watching her. She read the look on his face and knew that he was hiding something from her. He looked down and wouldn't hold her glaze for very long. She walked over to Sam and lifted his chin forcing him to look at her. She looked into his eyes and reached out to him using the bond she had with him. She waited and then it was like the door opened. His thoughts came flooding into her mind. She shifted though them and stopped when she caught one that she just couldn't believe was real.

I hope she doesn't find out about the drinking demon blood.

"Sam, tell me... Tell me that that isn't the secret way that you boosted your powers. Please, tell me that you are lying," she begged tears silently rolling down her cheeks.

"Katerina, come on. You knew my powers aren't like yours. They aren't natural. I needed some way to boost them and make them stronger," Sam said watching as Kat pulled away from him. He hated the look on her face. She was disgusted with him and disappointed in him. He hated it but knew that it was necessary.

"I thought you were just working with Ruby. Not fucking drinking demon blood! Fuck, Sam didn't you ever stop and think what the fuck you are doing?"

"I needed to protect you!"

"I could protect myself and you! Do not lay this at my feet! What the hell were you thinking? Really? Do you have any idea what the demon blood is doing to you?"

"It is making me stronger. It is going to make me strong enough so that I can destroy Lilith."

"That is not what I mean and you know it. I mean what it is doing to you on this inside, Sam. It is changing who you are. I knew you, Sam, or at least I use to know you. You use to be the most caring person I knew. You were my best friend."

"So, now I'm not. Is that it, Kat? I am no longer your friend if I do this?" Sam demanded tears coming to his eyes.

"You will always be my friend, Sam, always. You know that, so don't freakin stand there and think that this is me pushing you away. After everything we have been though together, you really think that I could turn my back on you? Do you?"

"You did once already, why not again?"

Sam watched as Kat looked away from him. He could see the tears falling down her cheeks and knew that he had stuck a low blow mentioning the night that she had pushed him away after he had kissed her. He had wanted so badly to call her his but she had pushed him away instead choosing Dean. Sam still wanted to call her his but knew that she would always love Dean. He knew that her and his brother were good for each other and as much as he wanted Kat, Addie deserved to have her parents together and happy. Sam couldn't stand in the way of that. He watched as Kat turned and looked back at him. Her grey eyes were filled with pain and he opened his mouth to take back what he had said. She held up her hand silencing any apology that he might have given her.

"You know why I didn't let it continue that night. I didn't want to hurt you. You were the only person I had here to depend on and I wasn't about to cause you more pain. You know that and you know that I can't feel what I feel for Dean, for you. I just can't, Sam. I love you but it isn't the same love I feel for Dean. That doesn't mean though, that I don't need you as much as I need Dean. I thought you understood that," she whispered.

"Kat, I'm sorry, I shouldn't-."

"But you did. I can't... I can't do this right now."

Kat walked away from Sam and out the door. She turned and leaned against the building. She closed her eyes and let more tears fall. She knew what she had to do now. She was going to have to bind Sam's powers. She knew that Sam and Ruby were going to be pissed. She sighed and knew that Dean would also be pissed when he found out what she had to do to bind Sam's powers. It wasn't going to be pretty if Dean found out. She opened her eyes and wiped her tears. She walked to the impala pulling out the keys and opening the trunk. She looked in there hoping that she everything she needed to start the binding. She found some of what she needed and knew that she would have to go back to the motel for the rest. She slammed the trunk and walked around the car and climbed in the driver's side. She started the car and pulled away. This night had turned into one of the worst ones she had ever had.
