The Doctor looked at the Sonic. "It says that the only thing different about this Kallioptian is that it has been bitten by a Neurotine."

"What's a Neurotine?" Rory asked.

I answered before the Doctor could. "I've heard of those, aren't they like ticks? We ran into them on another planet."

"Yes," the Doctor agreed, "They are like ticks. Well, they look like ticks, and they're parasites like ticks, but instead of sucking your blood, they just bite you. When you've been bitten, it affects your brain so you start talking nonsense, then attack everything around you, then suddenly, and randomly, die. After you are dead, the Nuerotines come and eat your body. They can't eat you unless your dead, so you don't have to worry. Also, if you get bitten, I can cure you."

"What's the cure?" Amy asked, "In case a Neuro- Whatever bites you."

The Doctor was offended. "One," he said, "It's a Neurotine from the planet Quanom. Two, I won't get bitten. But alright, the cure is-"

"Wait," I interrupted, "It's too quiet."

We cautiously went outside to find that the Kallioptian was dead. "Whew, that's a relief! Now we don't have to worry about getting attacked anymore." Rory said.

"That's not true," Amy objected, "The other Kallioptians that have been bitten could come and attack us."

"Amy's right, we have to find a way to get rid of all the Neurotines," I agreed.

I looked at the Doctor to see what he thought we should do, but he was just standing there staring at us.

Rory noticed and asked, "What's wrong with the Doctor?"

I answered, "I don't know. Doctor, what's wrong?" I didn't get an answer, and that's when I knew something was wrong. He was staring straight at us, and I knew he had heard us, but if he was alright then he would have answered. I frowned, thinking about what could have happened.

All of a sudden the Doctor said, "Hello Rose!"

We were confused. "Who's Rose?" Amy wondered.

"You're Rose!" The Doctor answered.

Amy shook her head, "No I'm not, I'm Amy, Amy Pond, remember?"

The Doctor announced, "You're wrong, you're Rose Tyler, and you have bushy eyebrows!"

"What?" Amy didn't know what to say to that.

Unfortunately, Rory started freaking out. "Something's wrong with the Doctor, I have to fix it, I'm a nurse, but I don't know how to cure him!"

Amy and I ignored Rory. "I think I know what's wrong with him," I say.

"Who, Rory?" jokes Amy.

"No, the Doctor. I think he's been bitten by a Neurotine. Remember, the first step is that they start talking nonsense, and the Doctor is certainly doing that." I explain.

"Yes, well, what do we do?" Amy asks me.

"I don't know," I reply.

A/N Plot twist! Well, I think it's a plot twist. Were you guys expecting someone to get bitten by a Neurotine when I explained about them? Probably. Were you expecting the Doctor to be the one bitten? I'm not sure. Oh well.

Enjoy!
