Doctor Who - Four Horsemen - Part 5

"It looks like the final trail has stopped, there's been a car crash... So I guess it's safe to say the death and destruction has started..." said Martha.
"Should we call UNIT?" asked Mickey.
"Right" said Jack "You three go and visit the sites, see if you can find out what happened or any information on these guys, weaknesses or anything like that, anything that will help us stop them, I'm gonna stay here, keep an eye on things and get a message to UNIT, keep them on their toes in case anything get out of control"
"We'll bring a containment unit" said Martha.
"Good plan Martha, and only use your weapons if it's absolutely necessary, remember, they are still people"
Mickey and Martha went to leave, The Doctor looked hesitant.
"She'll be fine Doc. She's tough" said Jack, handing him an earpiece.
The Doctor left with Mickey and Martha.
"Keep in touch" Jack saluted to him.
Jack looked over to the TARDIS and grabbed the medical scanner, he went into the TARDIS and checked on McKenzie, she was fast asleep. He held the scanner up to her until it beeped, then left the TARDIS. Details showed up on the scanner's small screen, he placed the scanner in a slot next to his computer and the readings appeared on the big screen in his office.
It showed a full x-ray of her body, her two hearts beating steadily. It read that she was perfectly healthy like nothing had ever happened. It also read that she was a female of unknown origin and age and that she was pregnant. Jack smiled.

The old lady, the large man, the shut in and the child met up in a park.
"My children..." said the old lady "It is good to be in full form again"
"Can we start now mother?" begged the large man "I'm so hungry! I need to–"
"Not just yet, Famine... One of us has been causing trouble"
"It was him mummy" the child pointed to the shut in.
"I know it was him, dear..."
"You should punish him..." the child's eyes glowed darker red.
"But mother, I was just–" pleaded the shut in.
"Acting on the wishes of your host. Which is not how we do things... your disease could spread too early. And there won't be anyone left strong enough to fight in the wars"
"Yeah!" said the child "You'll ruin everything brother!"
"Say's you! Creating unrest wherever you could! And you!" the shut in turned to the large man who was becoming more uneasy "You destroyed that restaurant"
"I was hungry!" shouted the large man.
"Boys, boys... now... you listen to your mother. We were released much too early and have been exposed to far too much of this planets toxic atmosphere. We need our ship to survive and it was stolen by these... humans"
"I will destroy them all!" screamed the child "I will tear them apart, limb from limb until we get it back... Then carry on killing them!" he laughed maniacally.
"Soon... but first we have to take down a small group of–"
"Easily..." scoffed the shut in.
"No, not so easily. They know of us... I sensed it. One of them, she touched the ship and sensed our energies. She could be our downfall."
"Ooh... what are we going to do?" whined the large man.
"Go with your brother, pestilence... create a distraction for them. War and I will take the ship back"

"How are you guys doing?" asked Jack.
"I'm at the house" said Mickey "A couple are fighting inside, I'm heading in"
"Doug's handling the police and the crowds, I'm going to have a look at the body" said Martha, putting on protective clothing.
"Are you sure you're not just sending me to get food?" asked The Doctor standing outside the restaurant.
Jack laughed "No, a cashier called the police a while ago but they've decided they have more pressing matters"
"Alright, I'll go and talk to her, but you're on your own if someone asks for fries"
"I could go for fries" said Mickey.
The Doctor sighed and headed inside, the place was empty.
"Hello...?" he said. He heard someone whimpering from behind the counter. He hopped over and had a look around, the cashier was hidden underneath.
"You're alright now" he placed his hand on her shoulder and helped her up "I'm Detective Inspector John Smith" he held up his psychic paper showing her a badge and ID "Do you think you could tell me what happened here?"
"There was this big guy– he came in a bought a meal like anyone else– but then– he just went crazy– just started demanding things and he threw his wallet at me!" she thrust the wallet to The Doctor's hands "Then he ate all the burgers off the grill– then..." she shuddered "He put his hands in the deep fat fryer! It was horrible!"
"Don't worry, he's gone now... just uh, go home and take the week off" he smiled. The cashier got up and left very quickly.
The Doctor looked into the deep fryer, the oil was stained red.
"No fries then..." said The Doctor. He sat up on the counter and looked through the wallet.
"Alright, alright, I'm leaving!" Mickey shouted as he was bullied out of the house.
"Something wrong Mickey?" asked Jack.
"So this couple Stephen and Carol Tench, they were having an argument and now half the street is arguing with them, over the fence and out in the street. They didn't even notice their kid got up and left"
"Oh god... there's a kid involved?" asked Jack.
"Looks like..."
"Martha, you found anything yet?"
"Yeah... it's looks like some sort of outbreak. This woman has so many diseases, all at once!"
"Is she contained?"
"The whole street has been cut off, all the houses evacuated and they're checking now... but somehow I think it's localised to just this flat... It's strange"
"What's it like in there?"
"Very... clean... Neighbours say the guy who lived here was a complete hypochondriac"
The Doctor laughed.
"Something funny?" asked Jack.
"It just tickles me that these creatures, these gas things... have a sense of irony"
"What?" asked Mickey.
"Well, this thing, spreads sickness right? And it takes a hypochondriac as a host? What else did McKenzie say...? Wars, chaos, pain, death... Oh, I get it... that's clever. You humans and your stories. It amazes me how far you can reach, it really does"
"What are you on about?"
"No, he's right..." said Martha "They're like the horsemen... War... Pestilence... Death?"
"What like, the apocalypse?"
"It's a good cover, I'll give them that" said Jack.
"They come to a planet and destroy all the life on it, then blow it up. Seems pretty apocalyptic to me" said Martha.
"So have you guys got anything?"
"Nothing here..." said Mickey "It's as if the kid just vanished and this street is breaking into a war" he ducked someone's punch "Everyone's gone mental!"
"I've only got a wallet" said The Doctor.
"I think I've got something..." said Martha "It's not much... but it seems off. It's a trail of dead bugs... If this guys flat was so clean, how did they get in? I'm going to follow it, see what turns up"
"It's a stretch, but it's all we've got, you two meet up with Martha"
"On my way" said Mickey.
"You're loving this aren't you Jack..." said The Doctor.
