DW: The Arrival of The Doctor.

"Well then, I say we set up a trap for the beast and capture it before it can slip away. God knowing what it might do if gets away from us. It could take days, weeks even to find it again." The Doctor said locking the Tardis doors. "But first things first, let analyze some DNA!" He said rushing over to the control panel. "There we are, look at you."

"What? Whats happening?" Carrot Top said while looking on.

"It's a zygon, no doubt about that but theres something else." He said looking at a screen. "Something that shouldn't be there, one second." With a few short movements and tugging at the controls, he waited anxiously for something. "There, thats it, what is that?" He said looking intensely at her and then back at the screen.

"What? Whats is it?" She asked while coming to his side.

"The DNA has been polluted, almost fused together with another creature's. Now, I am still a stranger to your world but it says that it is also this creature." He said pointing. "What is that."

Carrot Top looked at the screen and quickly grew silent. Though she never seen one in her presence, she had heard and knew enough to know that there were in trouble.

"Doctor, remember what I told you earlier about the changeling creature?" She asked.

"Yes?" He asked with a concern tone to his voice.

"Well that is a changeling if I ever saw one." She said. "Which means….of course!"

"What!" The Doctor jumped.

"If its a changeling that means its going after Mr. and Mrs. Cake relationship. Not only that but the love they had for they're children is also potentially food for it." She said.

"Now hold on, the terminal also says that this thing is a zygon. If thats true than we are dealing with something that has been affect with something from your world. Thus its assumed that its a part of whatever its fused with." He exclaimed.

Carrot Top sighed. "You lost me on that one."

He stopped for a moment and began mumbling to himself. "We have to act and fast. If these creatures are as dangerous as you say, then we need to get it away from the rest of the Cake family. Also we need to find Mr. Cake as well, no telling where he's all hung up."

Carrot Top thought carefully. "Where though, I mean he could be anywhere really. She said he wasn't feeling good and that he went to the hospital this morning. We should start there, and work our way back."

"Thats a good start, so shall we beam right over there?" He asked heading for the door. "Of course you'll have to point the place out."

"Right coming." She said trotting after him.

The two went down the street and made there way to the hospital that sat by itself. Apoun arriving, The Doctor quickly made observations with his eye, not risking anything to happen.

"It's followed us." He said slowly.

"What?" Carrot Top asked turning around.

The Doctor quickly grabbed her and forced her forward. "No don't look, it will know that we know and thats something it cannot know."

"So what do we do? Are you sure its following us?" She asked.

He smirked. "I know because its been following us ever since we left the cake shop. Once we got back to the Tardis the radar picked it up."

"But wait, is it safe leaving your ship in the open like that? What if it got inside?" She asked.

He chuckled. "Don't worry I locked it, snug as a bug. Even though that statement is odd. I mean really how snug can a bug be?"

"Doctor." She said growing anxious.

"Right, inside we go." He said moving forward. "It probably won't follow us inside, to close for comfort."

Carrot Top lead him to the front desk where ponies checked in. The clerk smiled as the two came closer to her.

"Hello, how can I help you today?" She asked.

"Yes hello, I am The Doctor and this is Carrot Top. We were just here to ask a simple question about one of our dear friends who check himself in today." The Doctor said while glancing behind him.

"Oh, are you visiting?" She asked.

"Not really, we just wanted to know the symptoms he was having. You know? Just to be safe while around him." Carrot Top chimed in.

"Oh, well I can look up why he checked himself in but I am not allowed to share cofidintal information. Also all imformation that he wishes not to be shared will not be repeated in front of others." She said pulling out a stack of papers. "What was you friends name."

"Carrot Cake." The Doctor said. "Mr. Carrot Cake, his wife said that he wasn't feeling good so he came here this morning."

The clerk rumbled though signatures and began growing a puzzled look on her face. She kept looking back and forth at the papers in the stack.

"I am sorry but there is no record of Mr. Cake ever checking in. If he did come here he would have to sign at least one of these forms. Are you sure it was the today and not a while ago? I can check last weeks records for you if you like?" She asked.

The Doctor pondered. "No, that won't be nessceary. Come Carrot Top we have something new to figure out."

The two walked out of the front door and were soon standing in the cool autumn breeze.

"So Mr. Cake didn't even make it to the hospital huh?" Carrot Top asked. "That means that he must have been taken somewhere along the road."

"Maybe." The Doctor said half heartily. "Or Maybe not, there is something fishy going on here and I don't like it. Like I said before the zygon is following us and I think its now retreating. It's probably scared now that we know something is up. It couldn't have done it in town cause somepony would have noticed. So that leaves us with two options."

"Which are?" Carrot Top questioned.

"Either he was attacked right in front of this place or he never got a chance to leave the shop." The Doctor said. "Thats where we're going to find him."

Carrot Top looked all around. "He's still right there in the shop!"

"Exactly." The Doctor said. "Come, we have have somepony to find and theres no telling what that zygon is up to."

The two began walking forward at a quick pace.

"But Doctor, should we stop by the Tardis first? I mean do you have a plan on catching this thing we're after?" Carrot Top asked.

"Haven't had a real thought about it actually now that you mentioned it." He said.

"So should we formulate a plan or what?" Carrot Top asked.

He shook his head. "Nah, I usually like to see where the situations takes me and then act."

Carrot Top frowned. "So you just wing it?"

"Yeah." He hesitantly said.

"Great, so this zygon is dangerous you say?" She asked.

"Eh, its not the worst thing in the universe. It's no dalek but its still a tuff customer. Though in this universe it is proboly the most dangerous thing that is living." He said very dry voiced. "I don't won't to worry you, but lets pick up the pace a little."

"Don't worry?" She chuckled. "A strange pony lands in my back yard in a big blue box and then takes me along to find an 'alien' from another world. Trust me if I was worried I wouldn't have agreed to come with you."

"So why did you come with me then. I was sure that you would have called the police or something for sure. Not that it would have mattered." He said with a grin.

"I really don't know actually." She paused. "It was just an impulsive action I guess."

"Well then, in the future maybe try not to jump the gun. Not all ponies who crash in your backyard in strange boxes are friendly you know?" He said jokingly.

His screwdriver was begging to beep causing both to stop in there tracks. They had just gotten to the center of town and almost nopony was around. The sun had already been deciding into the sky, it created long and dark shadows.

"Whats that all about now." The Doctor said taking a look at the tool. " Calm down, theres nothing that is around……us." He said while looking around. "Miss Top."

"Yes Doctor?" She asked.

"We're going to the Tardis right now." He said very slowly and calmly.

She noticed his behavior. "Something wrong?"

"It's here." He said. "And from the readings, its close."

The two slowly made there way to were the big blue box stood. The Doctor quickly opened the door and escorted Carrot Top inside. As soon as he locked the door a huge thud stroke from the outside. It sent Carrot Top's heart racing.

"Was that the zygon?" She asked.

"Yes." The Doctor said making his way to the control panel. "If I can just isolated the flow, then reconnected it to the tracker I will be able to track it anywhere."

"But can it get in here, I mean those doors are made of just wood right?" She asked as another loud knock came across.

"Nonsense, those doors are shielded. There is nothing in this known galaxy that can break through them." He said. "Now I have linked the DNA sample we got earlier to the the radar. So now wherever are friend goes, we can follow it." Another knock, this time much louder came across. "O! Do that again and I'll make you sorry you hear me!" He shouted at the door. "You also better not have done anything to that fellow you replaced or else you'll answer to me. Trust me, I won't be happy if he has come to harm." He had walked over to the door by the time he was finished.

There was no response, no knocking, just silence.

"Well then I guess he ran off then." He said returning to the panel. "Now we're cooking, we can now see where he is heading."

A map appeared on one of the screens. Carrot Top instantly became fascinated with it, how many other wonders did this place have in store. The Doctor looked over it, studying it until he took a deep breath.

"So he has returned to the home huh? Well then looks like we're going to make a late night visit to the Cake family. First though before I forget about it, we need a plan on getting in. I wouldn't like Mrs. Cake or the twins to witness the interactions between us and the zygon." He said.

"Thats going to be difficult then, I mean that things ready for us. Shouldn't we suspect that he knows that we're coming for him?" Carrot Top asked.

"He could." The Doctor said while pondering. "Then we shall come in an the most unexpected way that he would never see coming."

He quickly ran over to the control panel with a wild smile on his face. With a few switches and a slight pull on the lever the place started to rumble.

"Doctor?" Carrot Top exclaimed while trying to find something to hold on to. "What are you doing."

He let out a laugh. "If he's waiting for us to come through the front door then we'll just show up right in the middle of the place. Hold on, we'll be there shortly. Actually we'll be there in a couple of hours!"

The place jolted and slowly started to settle back down. Carrot Top was still shaking as the Doctor went over to the door.

"Still in one piece." He said with a hint of relief.

Carrot Top stood up. "Excuse me!"

"Nothing we're here." He said with a smile. "Lets go catch us an alien."
