"What do you think is down there?" Rita asked Rose wondering what she was currently thinkng while they waited for the Doctor in the drilling area to say goodbye before he went down.

"Oh I don't know what do you think?" She asked.

"What do I know" she corrected grinning. "I think whatever is down there will be fine" she told the blonde who looked quite anxious.

The Doctor walked in wearing an orange spacesuit the same as Ida's. "Capsule established. All systems functioning. The mineshaft is go. Bring systems online now." She shouted to the others.

The Doctor walked up to Zach who groaned a little. "Reporting as a volunteer for the expeditionary force." He told Zach.

"Doctor, this is breaking every single protocol. We don't even know who you are."

"Yeah, but you trust me, don't you? And you can't let Ida go down there on her own. Go on. Look me in the eye." He told Zach sho lookes at him. "Yes you do, I can see it." He explained to Zach. "Trust."

"I should be going down." Zach mumbled.

"The Captain doesn't lead the mission. He stays here, in charge." The Doctor looked at Zach seriously.

"Not much good at it, am I?" He shrugged then turned around talking loudly. "Positions! We're going down in two. Everyone, positions! Mister Jefferson! I want maximum system enhancement."

The Doctor walked over to Rita and Rose grinning looking at the little screen on his suits arm. "Oxygen, nitro balance, gravity. It's ages since I wore one of these."

"I want that spacesuit back in one piece, you got that?"

"And I want you back in one piece, I'm not getting stuck with Rose" she joked. I still don't know why I'm here and I'm going to find out one day"

"Yes, sir and yes sir." he nodded to them both being very serious then placed on his helmet.

"It's funny because people back home think that space travel's going to be all whizzing about and teleports and anti-gravity, but it's not, is it? It's tough." She thought.

"Very tough, but fun, very, very fun" Rose smiled at the brunette, nodded then walked off. 'Where is she going?' Rita turned towards the Doctor hiding the confusion on her face with a smile. "Don't be an idiot" she pointed at him lightly poking his chest.

"I'll try not to be" he laughed then pulled her in for a tight hug then pulled away holding her firmly by her shoulders. "Look after her" he spoke quietly.

"I will, until you get back" she smiled.

"Until I get back" he nodded smirking at her. He then let go of her shoulders and walked with her to what looked like a lift where Rose also was stood talking to Ida for a moment, he stepped inside and they both waved at him watching him and Ida slowly move towards the ground.

Rose then walked towards a microphone, Rita followed heading in the same direction of where the blonde went wondering why she had walked off, some things played out differently to how they looked by Rose walking was definitely not something Rita thought she would do.

"You okay?" She asked Rose now leaning against the equipment Rose was standing beside.

"Yeah, why?" She asked looked confused.

"Oh, you just walked off. I didn't know if something was wrong" Rita scratched the back of her head. 

Rose thought for a moment then shook her head. "No I'm fine, you said he'll be back so he'll be back" she smiled.

"You have a point" Rita nodded.

"When don't I?" Rose joked chuckling, Rita laughed a little at her comment.

"Ooo we can use this" The brunette picked up the microphone and handed it to Rose who grinned at her. They watched the progress of the Doctor and Ida on the screen in front of them.

"You've gone beyond the oxygen field. You're on your own." Zach informed them.

"Don't forget to breathe. Breathing's good." Rose said shakily in the microphone.

"I don't think he's that much of an idiot Rose" Rita laughed. The corner of the Doctor's lip slightly curved at the comment.

"You two, stay off the comm," Zach ordered.

"No chance" The girls both said in unison high fiving each other.

Rita then took the microphone from Rose "Just try and stop us, Zach, I know you won't"

"How do you know that?" Rose whispered to Rita so Zach wouldn't hear.

"He never stop you" she smiled smugly.

They snap their heads back towards the screen when the base shakes a little and the capsule drops. Rose grabbed the comm from Rita and spoke into it, her voice full of worry. "Doctor? Doctor, are you all right?"

"He should be fine" Rita reassured the blonde rubbing her back a little. "Should be there now"

"Ida, report to me. Doctor?" Zach demanded wanting confirmation obviously not trusting the brunettes word.

"Rita's right, you should listen to her a bit more. We've made it. Getting out of the capsule now." Rita grinned at his comment thankful that at least someone was listening to her.

"What's it like down there?" Rose questioned.

"It's hard to tell. Some sort of cave." He looked around then corrected himself. "Cavern. It's massive."

"It's pretty, Ida your going to love it"

"Well, this should help. Gravity globe." She said to the Doctor, a moment later there was a gasp, "that's... that's. My God, that's beautiful." Ida said in awe.

"Told you" Rita grinned smugly.

"Who's showing off now?" The Doctor asked.

"Since when did I say you showed off?" Rita questioned him.

"All the time, you do!" His voice rose to a higher pitch, Rita laughed at his small quirk. "Rose, you can tell Toby we've found his civilisation." the Doctor informed the blonde.

Rose looked at Toby not noticing the worry he was currently holding in his eyes. "Oi, Toby. Sounds like you've got plenty of work." 

"Good, good. Good." He tried to speak calmly hiding his face thinking the symbols were still covering him.

"Concentrate now, people. Keep on the mission." Zach reminded them, Rita rolled her eyes after eyeing the man crouched to the floor. "Ida, what about the power source?" He asked. 

"We're close. Energy signature indicates north." She looked at it again. "north-west. Are you getting pictures up there?" 

"There's too much interference. We're in your hands."

 "Well, we've come this far. There's no turning back." Rita groaned at how literal that is.

"Oh, did you have to? No turning back?" He looked at her. "That's almost as bad as nothing can possibly go wrong, or this is going to be the best Christmas Walford's ever had." He spoke sarcastically.

Ida looked at him a little annoyed. "Are you finished?" She asked.

"Yeah. Finished"

"Captain, sir," Danny spoke into a comm sounding a little frightened. "There's something happening with the Ood."

"What are they doing?" Zach asked him.

"They're staring at me. I've told them to stop, but they won't." Rita looked over at him then ran over to the railing watching the Ood.  

"Danny, you're a big boy,  I think you can take being stared at." She heard Zach through the comm. 

She then ran over to Rose taking the comm from her. "You haven't seen it, Zach, basic one hundred, I'm correct aren't I Danny?" He looked over to the monitor and blinked. "Yeah you are" He then started pressing things on the monitor. "I've checked. there isn't any fault. It's definitely one hundred." 

"But that's impossible," Zach muttered.

 "What's basic one hundred mean?" Rose asked looking at Rita a little worried.

"The Ood should be dead" She replied.

"Basic one hundred's brain death," Jefferson added.

"But they're safe. They're not actually moving?" Zach asked them. 

"No, sir," Danny confirmed. 

"Keep watching them. And you, Jefferson, Keep a guard on the Ood." He ordered. 

"Officer at arms!" Jefferson ordered a crewman and a woman holding guns beside them.

"You can't fire a gun in here. What if you hit a wall?" Rose questioned.

 "I'm firing stock fifteen. It only impacts upon organics. Keep watch. Guard them." He pointed at the Ood.

"Yes, sir." The woman replied. 

"Is everything all right up there?" The Doctor spoke through the comm, Rita and Rose both ran over to it and she picked it up. "Yeah, yeah," Rose replied. 

"How are things down there?" Rita asked.

"Everythings fine, we've found something though. It looks like metal. Like some sort of seal. I've got a nasty feeling the word might be trapdoor. Not a good word, trapdoor. Never met a trapdoor I liked."

"Shame you can't lick it to find out" She joked, don't even think about it" Rose looked at her strangely. "First the door when we were with Queen Victoria then a portable television, just giving him a warning not to." Rose smiled a little after understanding what she meant.

"The edge is covered with those symbols." Ida described it ignoring Rita's odd comments.

"Do you think it opens?" Zach asked her. 

"That's what trapdoors tend to do." The Doctor spoke for her.

 "Trapdoor doesn't do it justice. It's massive, Zach. About thirty feet in diameter." She guessed. 

"Any way of opening it?" 

"I don't know. I can't see any sort of mechanism." She looked around near the door.

"I suppose that's the writing. It'll tell us what to do. The letters that defy translation."

"Oh it will open all right" Rita muttered under her breath.

"Toby, did you get anywhere with decoding it?" Zach questioned not realising that the man wasn't able to hear him on the floor.

"Toby, they need to know that lettering. Does it make any sort of sense?"    Rose asked the man sitting on the floor in the same position as earlier.

"Toby, they need to know that lettering. Does it make any sort of sense?" 

"I know what it says." His voice now dark, deep and evil, not looking up he replied.

"Then tell them."

"Rose" Rita stepped forward a little beside the blonde.

"When did you work that out?" Jefferson asked.

"It doesn't matter, just tell them."

"He didn't work it out, " Rita told them as Toby looked up covered in the symbols again his eyes red staring up at them. 

"These are the words of the Beast. And he has woken. He is the heart that beats in the darkness. He is the blood that will never cease. And now he will rise." He slowly stood up grinning.

"Officer, stand down." He warned. "Stand down!" Jefferson shouted pointing the gun at him.

The Doctor heard the shouting and started to panic. "What is it? What's he done? What's happening? Rose, Rita?!" He shouted, "What's going on?!"  

"Jefferson? Report. Report!" Zach screamed through the comms waiting for an answer. 

Jefferson ignored Zach concerned with Toby at the moment in time. "Officer, as Commander of Security, I order you to stand down and be confined. Immediately!"

Rose grabbed the comm and started talking fast and scared. "He's come out in those symbols all over his face. They're all over him."

"Mister Jefferson. Tell me, sir. Did your wife ever forgive you?" the Beast that took over Toby asked.

"Ignore it,tighting" Rita told Jefferson. 

"I don't know what you mean." Jefferson continued pointing the gun at Toby blocking out the brunette.

"Let me tell you a secret. She never did." 

Jefferson tightening his grip on the gun. "Officer, you stand down and be confined."

"Or what?" he laughed.

"Or under the strictures of Condition Red, I am authorised to shoot you." 

"That won't stop it!" Rita gritted her teeth. Toby's mouth opened and the symbols left him flaoting over and entering the Ood. 

"But how many can you kill? It asked, Toby's mouth opened and the symbols left him floating over and entering the Ood. 

The Ood then spoke in sync. "We are the Legion of the Beast."

"Rose? What is it, Rita what is going on!" The Doctor shouted. "Rose? I'm going back up." He turned around. 

"Report. Report!" Zach shouted from the control room helpless and trying to understand what was going on.

"It's the Ood." Rose spoke in the comm.

"Sir, we have contamination in the livestock." Danny told Zach through the wrist-comm.

"Doctor, I don't know what it is. It's like they're possessed." She told him.

"Stay with Rita!" He shouted. 

She took the comm from the blonde who was slightly shaking. "She isn't going anywhere" Rita promised him.

"They won't listen to us." Jefferson watched the Ood slowly walking over to the stairs, starting to walk them towards the group on the catwalk watching from the railing. 

The Ood continued to speak in sync. "He has woven himself in the fabric of your life since the dawn of time. Some may call him Abaddon. Some may call him Kroptor. Some may call him Satan or Lucifer." They reached the group then stopped.

"Captain, it's the Ood. They're out of control!" Danny shouted.

"Or the Bringer of Despair, the Deathless Prince, the Bringer of Night."

"Everyone get back!" Rita shouted at them, one of the globes is released from an Ood's hand flying to a guard's forehead and electrocuted him.  

"These are the words that shall set him free." 

"Back up to the door!" Jefferson ordered them backing up with the others, Rita took the blonde's hand who was standing beside her knowing how shaken and terrified she was right now, just like herself but it was pointless her looking just as scared, she knew they made it out alive, Rose didn't.

"I shall become manifest." 

"Move quickly!" Jefferson shouted at them eyes locked on the Ood.

"I shall walk in might." The Ood continued.

Jefferson saw the door near them then pointed. "To the door! Get it open!"

"My Legions shall swarm across the worlds."

"We're moving! The whole thing's moving. The planet's moving." Rita and Rose heard Zach shouting through Danny's wrist-comm.  

"I am the sin and the temptation and the desire. I am the pain and the loss"

"Get that door open!" They were now all backed up against the wall trying everything they could to open the door.

"The gravity field. It's going! We're losing orbit! We're going to fall into the black hole!" Zach screamed.

"I have been imprisoned for eternity. But no more." The Ood were now close to the group still talking in sync with each other. 

 Door sealed.

"Come on!" Rose shouted banging on the door trying to get it open.

Door sealed.  The computer repeated.
