Murphy slowly reached forward and grabbed the cloth from my hand. He started wiping my face.

"You had my blood on you," he explained.

I couldn't help the smile and the breathy laugh.

I cleaned him up in silence after that.

"I'm going to go get some more water," I said, standing up.

I headed out for the water. It was light out again, just after dawn.

I walked over to the water but never made it there. Someone was coughing up blood by the fire.

I hurried over, eyes wide.

"Cory, stop," Clarke called.

I paused and looked at her.

"No one touch him," she said. She gave me a look and I knew. It was Murphy. I'd already been around him enough. If I was gonna get it, I'd already have it. It couldn't hurt to help out now.

So I grabbed his arm and put it over my shoulder. I helped him up and we made it to the dropship, Clarke right behind us.

Murphy was throwing up blood.

I sat the guy I was helping down and leaned him against the wall. I went and stood next to Clarke, who was kneeling in front of Murphy.

"I need you to tell me exactly how you escaped from the grounders. What happened?"

"I don't know," he said, shaking his head. "I woke up, and they forgot to lock my cage."

I knew what that meant. They let him go. They wanted him to come back here, to infect us.

"There was no one there, so I took off."

"They let you go," Clarke sighed, looking up at me.

I heard someone coming in. I turned to see it was Bellamy.

"Bellamy, stay back," I said, holding up my hands.

"Did he do something to you?" he asked, glaring at Murphy. Clarke and I just shook our heads. "What the hell is this?"

"Biological warfare," I sighed. "You were waiting for the grounders to retaliate for the bridge? This is it." I paused and looked down at Murphy. "Murphy is the weapon."

I knelt down again and grabbed the bowl of water. I started cleaning Murphy's face a little.

"Cory," Clarke said, stopping me. "You might not have it yet."

"Trust me," I said with a look. "If I'm gonna get it, I already have it."

"Is this your revenge?" Bellamy asked, pacing a little but still glaring at Murphy. "Helping the grounders kill us?"

"I didn't know about this, ok, I swear," Murphy said.

"Stop lying," Bellamy practically yelled. "When are they coming?"

"Murphy, think, all right?" Clarke said. "What can you tell us that's useful? Did you hear anything?"

"They are vicious, cruel," Murphy said, looking at me this time.

"You want to see vicious?" Bellamy asked, walking over.

"Hey, don't," I said, holding up a hand and looking at him. "Whatever this thing is, it spreads through contact."

"Clarke?" I looked past Bellamy and saw Finn was walking in.

"Finn, you shouldn't be in here," Clarke said. "No one should."

"I heard you were sick," he explained. He was so cute…annoyingly cute. "Clarke, what is this?"

"I don't know, some kind of hemorrhagic fever," she sighed. "We just need to contain it before-"

She was cut off as the kid I brought in starting throwing up.

I stood up and hurried over. I knelt next to him but there was nothing I could do. He had to get something out of his system. He was throwing up blood and coughing violently. And just as quickly as it started, it was over.

I knew before I even felt for a pulse that he was dead.

"Is he-" Bellamy started.

"He's dead."

I stood up.

Clarke was pouring alcohol on Finn's hands. Apparently he touched her.

"What do we do?" Finn asked.

"Quarantine," Clarke said. "Round up everyone who had contact with Murphy. Bring them here."

"And everyone they had contact with?" Bellamy asked.

"Well, we have to start somewhere," Clarke said.

"Connor," I spoke up, looking over at him. "Who as with you when you found him? Who carried him in? Think."

"The first one there was Octavia," he said.

Bellamy hurried out of the dropship. I turned to follow but Clarke stopped me.

"Wait," she said. "Just because you aren't showing the symptoms, doesn't mean you don't have it."

"Clarke, I feel fine. I'll just help those who are having trouble standing." I shrugged. "I'm like the only one who can."

She sighed and let me go.

I found someone right away. He was staggering on his feet so I helped support his weight. I brought him in and laid him down. I made sure he was on his side so that blood wouldn't go into his lungs. He could die from that. I don't want anyone else dying.

I turned to head back out there but Bellamy was coming in with Octavia. He blocked my path.

"You gonna move?" I asked, raising an eyebrow.

"Go lay down," he said.

I smiled. "No thanks."

"You might not have it."

"Oh please," I scoffed. "I have it. I just don't have any symptoms right now."

He was lucky. Two people were coming in, one barely standing. I helped her, giving Bellamy a look.

He can't tell me what to do. If there's a way to help, I'm gonna help.

For the next half an hour, we worked on getting anyone who might be sick in the dropship. Those who are symptomatic are on the first level, those not symptomatic are on the third level, except for me. I helped people in, got them water, cleaned up some blood, and tried to keep people alive.

A couple of the stronger ones carried out the dead bodies. There were already two of them.

I heard Bellamy telling everyone to get back to their posts. Then I heard him calling for Octavia.

Crap. Clarke had sent Octavia to go meet Lincoln. He was gonna be mad.

Suddenly I was hearing a lot of yelling. People were freaking out.

I jumped up and ran outside.

Chaos.

Guns were being pointed, people were yelling and bleeding.

I turned and grabbed a gun from just inside the dropship. I pointed it in the air and fired.

Everyone froze, looking over at me. I took a few steps forward and stopped next to Clarke. She had run out to try to stop them all. We were now near the middle of the group.

"Everyone just stop," I sighed. I looked around. "This is exactly what the grounders want. Don't you see that? They don't have to kill us if we kill each other first."

"They won't have to kill us if we all catch the virus," someone said, stepping forward. They held up a gun. "Get back in the damn dropship."

Bellamy grabbed the gun and elbowed the guy in the face. He fell back, clutching his nose.

"Not to state the obvious," he said, looking over at us. "But your quarantine isn't working."

Finn suddenly stepped forward. I looked over and saw Clarke was falling.

"Finn, don't touch her," Raven yelled.

He caught her anyway. He scooped her up into his arms.

"Hey, let me go," Clarke said. "I'm ok."

"No, you're not," Finn sighed. He was right.

"Octavia will come back with a cure," I said, looking at Clarke.

"There is no cure," Octavia said, pushing through the crowd. "But the grounders don't use the sickness to kill."

"Really?" Bellamy asked. He pointed to the two dead. "Tell that to them. I warned you about seeing that grounder again."

"Yeah? Well, I have a warning for you, too." She looked around. "The grounders are coming." She paused. "And they're attacking at first light."

Octavia helped Finn get Clarke into the dropship.

"Anyone sick, let's go, in the dropship" I called. "Everyone else. Put the guns down and get back to work. If someone's bleeding, let them know…but do not point your guns at each other again."

I turned and walked into the dropship.

"What else did Lincoln tell you?" I asked Octavia as Finn got Clarke situated. Murphy had given up his hammock.

"The virus doesn't last long."

"It's true," Murphy said. "I feel better." I smiled at that.

"They need to stay hydrated," Clarke said.

"You need to stay hydrated," Finn pointed out.

"I'll do it," I said, looking down at Clarke. "Just rest."

"I'll help you," Murphy said.

We started helping everyone up so they could drink some water. If it passed for Murphy, how many other people will be okay? I'm hoping everyone. But the virus is strong and not everyone is strong enough.

"You need to save yourselves," I heard Clarke say. I tried not to roll my eyes. "Just leave camp. Take anyone healthy enough with you."

"If you think that's even a possibility, you don't know me very well." That was awfully cute.

"Look," Murphy said, walking over. "At this rate, when the grounders get here, there won't be anyone left to fight back."

"That's the point," Octavia said.

"Then we slow them down," I said, slowly. I stood up and looked at them. They were all confused. I turned and ran from the dropship. I quickly made my way over to where Raven was making bullets.

"It won't matter if there's no one left who can shoot," I said, interrupting them. Bellamy, Raven, Monty, Jasper and Harper were all there talking about bullets.

I looked at Raven. "What do we need to build a bomb?"

"Depends on what you're trying to blow up," she said with a shrug.

"How about a bridge?"

"What are you talking about?" Bellamy asked.

"Murphy says he crossed a bridge on his way back here from the grounders' camp," I said. "Sound familiar?"

"Yeah," Bellamy said with a nod. "So what?"

"So the virus is fast," I said. "He's already getting better. Blowing the bridge won't stop the attack, but the longer we can delay it, the more of us will be able to fight."

"Even if Murphy is telling the truth," Bellamy said. He paused and added, "And that's a big if. That bridge has survived a nuclear war and 97 years of weather."

"It won't survive me," Raven said. I smiled.

Bellamy, Jasper, Monty, Raven and Finn, who had just walked in, got ready to head to the crash site. They needed the rocket fuel.

While they worked on that, I turned to leave.

"Cory," Bellamy said, stopping me. He glanced back at the others before ducking outside. I followed.

"How are you feeling?"

"I'm fine," I said, shaking my head. "And Octavia's okay too. I'm pretty sure we're immune."

"Pretty sure?"

"As sure as I can be," I said. "Would you mind letting Nate know? I don't want to risk him getting sick."

Bellamy nodded. I turned but paused. "And tell Raven to be careful."

I walked back to the dropship. For hours, I walked around. I made sure people were hydrated. If they started coughing a lot, I turned them on their sides.

It was late into the night when I took a short break. I just needed to breathe some clean air.

I walked out and leaned against the side of the dropship. I closed my eyes and leaned my head back.

"Bellamy!"

I opened my eyes and looked around.

"No! Stay back."

Crap. Someone else was sick.

I pushed off the dropship and followed the noise. Jasper was standing and talking to Bellamy. He was lying on the ground, half on top of a tent.

I rushed forward and knelt next to him. I put my hand against his forehead. He was burning up.

"Come on," I sighed. "You're gonna be okay." I helped him up and another person helped me get him into the dropship.

I laid him down and stepped back, just in time to avoid blood on my shoes. Octavia rushed to his side as I headed over to get some water for people.

No more breaks. I needed to help these people. They were all in pain and in danger of dying. I wasn't. I needed to help.

For another half an hour, I helped some more people.

"I'm gonna go check outside," I told Murphy. I reached up and kissed his less wounded cheek. "Be right back."

I stepped over people and made it outside.

"Monty," I said, stopping him. "Where are you going?"

"My best friend is about to blow up a bridge," he said, clutching the gun. "He might need some help."

"Let's go," I said, jogging toward the gate. We slipped outside and started running.
