I left the boys after we returned to the states. I was going back to Bobby's to find a hunt but I never made it there. Sam called me before I entered Sioux Falls.

"Robin, where are you?" he sounded panicked. Maybe a little too panicked like he was faking it.

"Nearly to Bobby's. What's going on?"

"Limestone, Illinois. ASAP." Sam disconnected and I spun the car around and headed back East.

Sam answered the door to the motel room they were in. The room was dark and there was a lamp busted on the floor. I looked up at Sam concerned.

"What is it?" I asked.

"You called Robin?" I heard Dean groan from inside the room. I stepped in and saw him laying on a bed with a wet cloth over his eyes.

"Are you okay?"

"Shh. Please be quieter."

"Are you… hung over?"

"He's a vampire," Sam answered calmly.

"What?!" I yelled turning around.

"Please, shhhh," Dean hissed grasping his head.

"You're fucking with me," I said to Sam quieter.

"We're going to figure it out," Sam told me and I knew he wasn't lying. He wasn't the joking type anymore. I took three long strides over to Dean and noticed the blood still smeared across his mouth.

"Robin, step back," he said holding a hand out to me and scooting away.

"How did this happen?"

"I can hear your blood, Robin. Please could you just go to the other side of the room."

"Sam, you better start talking," I snapped ignoring Dean.

Dean huffed and stood up shoving past me and heading to the bathroom.

"Where you going?" Sam asked him.

"Bathroom, okay? News flash, Mr. Wizard. Vampires pee!" Dean slammed the door behind him which I'm sure only worsened his head.

"What happened?" I asked again.

"We were going after some vampires. Got split up. One got the upper hand on Dean and got some blood in his mouth. Now his senses are going haywire."

"Great. How the hell do you unvampire someone?" I was pacing and stopped when I realized I couldn't hear Dean moving around in the bathroom. Sam noticed too.

"Dean?" he asked and knocked on the door. When no one answered Sam opened it up to reveal an empty bathroom and an open window.

"Dammit!" I cussed grabbing my keys.

"Samuel is on his way here," Sam told me.

"What the hell is he going to be able to do that we can't? We've got to find him before he hurts somebody Sam. Come on."

"Robin, just wait," Sam stopped me. "He probably took the Impala. There's no telling where he is. Let's wait until Samuel gets here and work together. We'll find him."

"And then what?" I asked Sam bitterly. "We cut his head off?"

"Robin-"

"Sam, we have to fix this."

"We will." Sam picked up his phone to call Samuel and explain the situation. An hour later there was a knock on the door.

"Can't keep track of your brother now?" Samuel sneered walking in the room.

"Well, I didn't think he'd just-" Sam started.

"He's not himself, Sam. He's a monster and he's hungry. You gotta be prepared to do the right thing."

"We can't kill him, Samuel," I snapped.

"Well we might have to now, princess," he snapped back. I took a step towards him but stopped when someone spoke behind me.

"I told you he'd kill me when he showed up," Dean said leaning against the counter. Sam and Samuel drew their machetes.

"Did you feed?" Samuel asked.

"I went to say goodbye to Lisa, which, for the record, was a shitty idea."

"Dean, answer the question," Samuel demanded.

"You can relax, I didn't drink anyone."

"Thank God."

"But I came close," Dean said and removed his jacket. He looked over at me with regret and sadness in his eyes. "All right. Do it."

"Dean-" I tried.

"If you insist," Samuel said.

"Wait!" I called stepping towards Samuel who advanced on Dean.

"Or I can just turn you back," Samuel told Dean ignoring me. I paused and looked confused between Samuel and Dean then over to Sam who didn't seem surprised.

"What?" both the boys asked.

"I didn't drive all this way to kill you, Dean. I'm here to save you."

Samuel walked back to his bag and pulled a book out. He set it on the table and gestured for us to sit. He opened the book up and slid it across the table to Dean.

"That's my grandfather's journal. Cure's an old Campbell recipe, kind of like the soup. No one's tried it since God knows. What I hear… this stuff is a bad trip."

"Awesome," Dean groaned.

"Hey- the cure is good. But a lot of this is on you. You drink, you're done. It won't work. I'm talking one drop of human blood."

"I got it."

"Do you? Because you will feed. It's a matter of time."

"What else do we need?" Dean asked slamming the book shut.

"Some stuff we got, some stuff we gotta get. Trickiest thing on the list, blood of the fang that turned ya."

"That guy was huge," Sam commented.

"There's nothing in the recipe about easy," Samuel told him.

"I can get it," Dean said standing.

"You're gonna walk right into the nest?" Samuel asked.

"Well, I'm one of them, aren't I? So all I gotta do is get in there, get the guy alone, and shoot him with so much dead man's blood that he'll think he's rushing a fraternity."

"I should come with you," Sam said.

"No. Dude, you reek. You're like a walking hamburger. I gotta do this solo."

"Yeah, except- we haven't been able to find him yet."

"No problem," Dean said pulling his jacket back on. "I can smell him. Two miles east of town. You guys get the other crap and meet me there."

"You have some dead man's blood?" I asked.

"I think there's some in the trunk," Dean paused.

"I have some. Hold on." I stood and followed Dean out of the room. He stayed as far away from me as he could.

"Robin, just give me your keys. I'll get it."

"It's under some stuff. You'll never find it."

"Robin! Please! I can't walk next to you!" Dean demanded. "You're the worst of all of them. Just give me the keys. I'll leave them behind the front wheel." I sighed and pulled my keys from my pocket.

"Be careful, Dean," I said handing them over to him. He took them from me slowly.

"If this doesn't work-"

"It will," I interrupted. "I'll see you later." I turned and went back to the room without another word to Dean. The cure had to work. If it didn't, I would never let Samuel take his head off. I'd just find another way.

We took Samuel's van to the nest following the directions Dean had given us. We saw the Impala parked on the side of the road and Samuel parked in front of it.

"This must be the place," Samuel said looking around.

"Shh," Sam hushed us as he heard something. A thud sounded on the roof of the van and a vampire leaned over and busted the drivers side window out to get to us.

Sam and I jumped from the van and Sam took the vampires head off. Samuel got out last and we headed towards the building where the nest was. We snuck in but I was surprised at the lack of vampires we ran into as we got further and further into the warehouse. I thought it might be a trap and then I walked out onto a balcony and saw a figure down below us.

Dean sat in the middle of the room, bloodied and holding his machete. Surrounding him were bodies of vampires. Under his foot was the head of the leader.

"Dean, you okay?" Sam asked.

"Yeah, I'm good," Dean replied after a pause.

We collected a syringe full of the leaders blood and returned to the motel. Dean rode alone to resist the temptation now that we were so close to healing him.

Once we were back in the motel Dean was wincing against his heightened senses and staying as far away from us as he could. Samuel started mixing the ingredients into a jar and Dean walked over to join us at the table.

"If this works, you know it's not gonna be a kiddy ride," Samuel said adding the vampire blood.

"That's great. Light her up," Dean snapped.

"So what'd you see in there?" Sam asked and I looked at him suspiciously.

"What?" Dean asked confused.

"In the nest. What'd you see?"

"Sam, I can't hear you," Dean said loudly. "Your blood is so frickin loud, okay? Just back off." Samuel poured the mixture into a mug. "All right, give me the damn cure." Dean took the mug and sniffed it. He recoiled disgusted then gave us a forced smile. "L'chaim…"

He tipped the mug back and chugged the potion. It dripped down his chin as he drank it quickly, gagging. When the mug was empty he gasped against the taste and spit the residue from his mouth.

"I don't think it-" Dean twisted around quickly and started throwing up a dark liquid into the garbage can.

"Dean!" I moved towards him concerned but Samuel stopped me.

"Is it working?" Sam asked.

"Either that or he's dying," Samuel said drawing his machete.

I looked worried from him back to Dean. Dean was now gasping and threw his head up groaning against the pain. His eyes were bloodshot and his fangs were out. He fell over and curled up gasping for breath. Suddenly he stopped moving and fell over on his back.

I thought for a moment he was dead but his eyes opened up and his breathing started again.

"Dean?" I asked timidly. He didn't answer and looked around confused. "Dean, are you okay?"

I stepped towards him and he looked up at me. Sam walked over and helped Dean sit up. I went to the sink and got a glass of water and handed it to Dean. He nodded at me and took it.

"Everything good?" Samuel asked.

"Yeah- I, uh, I think so," Dean answered.

"Can you stand?" Dean nodded and started to get to his feet. Sam helped him stumble over to the bed where he fell back and was almost immediately asleep.

"The next couple of days will be rough for him," Samuel said. "I'll stay until he's better."

"Nah, Robin and I can handle it," Sam said, all but rushing Samuel out of the room.

"I think I better stay, son. I'm the only one who knows what's going on here."

"I think he should stay, Sam," I said surprising even myself by agree with Samuel. But, Sam had been extra weird lately. Completely unconcerned about Dean being a vampire. Ready to take his head off and move on to the next hunt. "Just until your brother is better. Then I'm gone too."

The next few days sucked. Dean was sicker than I'd ever seen him. He was constantly switching between being too hot or too cold. He couldn't keep any food down and his eyes still looked awful.

He jerked the blankets off of him again as another hot spell came over him. I grabbed a bottle of water from the refrigerator and took it to him.

"I can't drink that, Robin."

"You have to try, Dean. We didn't save you from being a vampire just for you to die of dehydration a few days later."

"I'm fine."

"Dean Winchester, drink the damn water or I will force it down your throat." Dean looked up at me weakly and took the bottle. He took small sips of it until I was satisfied and I walked away. He managed to keep it down and I thought he must be getting better.

Slowly, the hot and cold flashes became fewer and fewer and eventually he was able to eat some soup without getting sick. I was so thankful when he finally said he felt good enough to leave. He was always a pain in the ass when he was sick.

Dean was in the shower and I packed up my bags preparing to leave again. Sam and his grandfather were packing up their things too.

"Hi," Sam greeted his brother when he emerged from the bathroom. "So, what'd you see?" Dean and I both looked at Sam confused.

"What?" Dean asked.

"In the nest. What'd you see?" Sam urged. I looked over at him suspicious. That's what he was worried about?

"Uh, well, I'm still trying to work through it, but, uh… I'm pretty sure they're not figuring anything out on their own. They're getting their orders from the top… where to go next, everything."

"Top, as in?"

"Their alpha. At least, that's what I think it is. They've got some sort of psychic thing happening. He sends 'em, uh… I don't know- messages?"

"Saying what?"

"Honestly? Recruitment drive. Their alpha's building an army."

"Well, that's comforting," Samuel said.

"That's not the worst."

"Then what is?" Sam asked.

"We don't scare them anymore."

I finished packing and threw my bag over my shoulder.

"I'll see you guys on the flip side. If you need me I'll be at Bobby's," I said and headed out the door.

"Robin!" Dean called coming after me. He caught me just outside the room and closed the door behind him so Sam and Samuel couldn't hear our conversation. "You gotta stay."

"Wow, you've resorted to begging? That's a new low, Winchester."

"Robin, I'm serious. It's Sam. I know you noticed him."

"Yeah. He's different. We knew that."

"It's worse than we thought though."

"What do you mean?" Dean looked back towards the door and led me further down the hallway.

"When that vampire was turning me, Sam was there. He just watched. And, I dunno, I could've sworn he looked… pleased."

"Pleased? That you were being turned into a vampire?"

"I know it sounds wrong but he didn't do anything." I took a breath and considered this information.

"So, you think Sammy's corrupt somehow? It's not possession. We checked him."

"I know. It's gotta be something else but something is wrong."

"I'll stay. But things aren't fixed between us." Dean nodded and I walked past him back into the room. "Never mind, boys. Looks like I'm tagging along a little longer."
