A/N - I decided to be nice and give you guys another chapter this weekend.

Elise spun around and immediately tried to sonic the control panel again, but it kept giving her a thumbs down. "Apparently, it doesn't take too kindly to being soniced," Elise said. Elise took apart the control panel and started fiddling with the wires.

Clara reached out to try and help, only to have Elise smack her hand away.

"Do you know what you're doing?" Maisie asked.

Elise sighed. "No." River would know what to do. She always knew what to do.

"Do you ever wish bad things on people?"

"Oh, yeah. All the time," Clara said.

"Whoever designed this door," Elise snapped.

"She wasn't really my mum. She just made me call her that. She was my gran. Do you know why I wanted to see her body?" Maisie asked.

"Because you loved her very much and were missing her?"

Maisie laughed. "No. You obviously never met her. No, I just felt really guilty. Like I'd been picturing her dying for years. Like a daydream. Not really meaning it. At least, I don't think I did. But now, it just feels like I made this happen."

Clara walked over to her. "Hey, listen. You didn't do anything wrong. Difficult people, they can make you feel all sorts of things. But you didn't do it. You didn't kill her. She just died."

"Are you sure about that?"

Elise eventually gave up on the control panel and sat down next to Maisie and Clara.

"This Doctor. He's your what, exactly?" Maisie asked. She looked at Elise.

"He's my father. Well...adoptive father."

Maisie looked at Clara.

"He's not my anything."

"Oh, you mean you're just friends."

"Yeah, Of course we're just friends. Oh. Well, not even friends, not anymore."

"Well, that clearly isn't true."

"It's true. It is. It's very true."

"You do seem to be here together." Maisie turned to Elise. "That must be awkward."

Elise laughed. "You have no idea."

"Seriously? We're stuck in this carriage, probably all night, and all we can talk about is some man?" Clara asked.

"Some man?" Maisie asked.

"Not that kind of. Look, we, er, we knocked about together, we traveled and now we're stopping. This is a, I don't know, goodbye to the good times?"

"Were the good times all like this?"

Clara laughed. "Yeah. Now that you mention it..."

Elise's thoughts drifted to the man she'd met in the café and those blue eyes that haunted her. Maybe she would find him again one day.

Clara and Maisie continued to gossip about the Doctor.

"Oh, he was wrong," Maisie agreed.

"Yes. Yes. Yes, he was."

"And, and high-handed and, and thoughtless and, and, and arrogant beyond belief."

"Exactly." "And you got on a train with him."

"I was saying goodbye. You can't end it on a slammed door."

"Yes, you can. Anyone can do it. People do it all the time. Except, of course, when they can't." Maisie sighed. "Life would be so much simpler if you liked the right people. People you're supposed to like. But then, I guess there'd be no fairy tales."

Clara's phone started ringing. "Doctor? Doctor, please, I'm...Elise and I are in trouble. Doctor. Doctor, please, just li...Doc...We're trapped! Elise tried sonicing the door and it won't open!"

A few minutes later, there was banging on the door.

Clara put her phone on speaker. "Clara! Ellie!"

Elise's hearts nearly broke hearing the Doctor use her old nickname.

"Is that you?"

"Yes. Yes. Hello. Can you hear us?" Clara yelled.

"Computer, can you open the door, please?" the Doctor asked.

"Call me Gus. I'm afraid this door can only be opened by executive order," the computer said.

"Oh. Forget it. Elise! Have you tried the sonic?"

"It let me open the door, but it won't respond now! I tried rewiring it, but..."

The Doctor tried sonicing the door. "There must be some sort of a suppression field. Either that or Elise completely soniced it wrong."

"Oi!" Elise snapped.

"What are you even doing in there?"

"Well, I was looking for you Mister Nothing To Worry About!"

"What, was I supposed to waken you up? Drag you out of bed because I had a hunch? I thought you didn't want to do this anymore."

"Look, look, please, can we just not do this now? I think we might not be alone in here. There's a sarcophagus."

"Is it in there?"

The light on the sarcophagus changed from red to green. It started to open.

"I think we might just be about to find out. Turns out the sonic is working. Just not on the door we need."

The lights started flickering.

"Clara, it's coming."

Clara walked up to the sarcophagus. "Doctor?"

The lid swung wide open.

"Doctor, it's okay. It's...um...it's full of bubble wrap."

"Clara, I'm gonna have to call you back."

"Doctor!" Clara stared down at her phone.

Elise's brain leapt into action. She started opening boxes.

"What are you doing?" Clara asked.

Elise pulled out some papers. "Research. I can't just sit around and not help him."

They searched until they found something they could use.

Clara called the Doctor.

"Clara Oswald!"

"Elise. Okay. So, first things first. The sarcophagus is actually a secure stasis unit."

"Yes. It's where they want us to put the Foretold if we capture it."

"Well, that would have been good to know," Clara said.

"Sorry. Teeny bit busy round here. What else?"

"We have some paperwork. Passenger manifests from other ships. Maisie recognized a couple of the names. These are missing ships."

"So, we're not the first."

"No. Unfortunately," Elise said.

"I've got some progress reports. The Gloriana spent three days getting picked off by the Foretold. All died. Performance marked as poor. The Valiant Heart. Forty-two crew, four died. Performance, promising."

"Clara, I have to go. And Elise?"

"Yes?" Elise asked.

"Clever girl." The Doctor hung up.

Elise could see the smile on his face. She felt like she was flying. This was the first bit of real praise she'd received since the Doctor regenerated.

The Doctor and the rest of the scientists and doctors had deduced that Maisie was the next one on the mummy's kill list.

"Look, she's had a bad day. That's all," Clara told him.

"Clara, it doesn't care. Her bad day, her bereavement, her little breakdown puts her squarely in its cross hairs. She's next. Every simulation we've run confirms it."

"Okay, but, but we're in here and, if we stay in here, that thing can't..."

"This thing can teleport. We need her here. Even the computer agrees."

"Okay, so you can save her? Right?"

"Of course not. Why would you think that? This is another chance to observe it in action."

"As it kills her," Elise snapped.

"Of course, as it kills her. If it happens in there, it'll be a waste so bring her to us."

"No. No way."

"How? How exactly? She's never going to agree to this," Clara said.

"Well, I don't know. Lie to her. Tell her I can save her. Whatever it takes to get her here." The Doctor hung up.

"We cannot sacrifice her," Elise told Clara, "We can't."

"What's he saying?" Maisie asked.

"He says. He says he can save you," Clara said.

Elise stared at her friend in disbelief.

The door opened and they walked out.

"I knew he could get us out of there. I told you, he's a good man."

Clara tried to run to the TARDIS, but a barrier stopped her. "Yes. Yes, he is."

"And to be honest, I don't know how convinced I am by this trauma sense thing, but if the Doctor says he can help me anyway, I mean, that has to be a good thing, doesn't it, Clara?"

They walked down the corridor towards the main car.

Elise felt like she was leading Maisie to her death.

The door opened and the trio entered.

The Doctor ran over to Maisie and shook her hand.

"Hello, again. I'm Maisie."

"Good for you."

"We passed the TARDIS on the way here. Thought about getting inside, hiding, pulling the levers and hoping for the best. But we couldn't even get in. There was a forcefield around it."

The Doctor picked up a scanner and used it on Maisie. "It's probably Gus trying to block our escape route."

"But how does he even know what it is? Cos if he knows what it is, then he knows what you are."

"Well, he has tried to entice me here before. Free tickets, mysterious summons, he even phoned the TARDIS number..."

Amy and Rory's wedding! Someone had called the Doctor as they were leaving! Elise always wondered why he had taken them on that adventure with Kazran and the fish instead.

"Do you know how difficult a number..."

"You knew. You knew this was no relaxing break. You knew this was dangerous."

"I didn't know. I certainly hoped."

"Okay, this. You see, this. This is why I'm leaving you. This. Because you lied. You lied to me, again. And now you've made me lie. You've made me your accomplice."

"What? Sorry? When did you lie? Clara?" Maisie asked.

"Maisie, I am, I am so sorry."

The lights flickered and Maisie pointed.

"Do we start the clock?" a man asked.

"Not yet." The Doctor stood in front of Maisie and flashed the scanner in her face.

"Focus. Focus. Focus! All of that is your grief, your trauma, your resentment. And now..." He put the scanner to his own head and zapped himself. "It's mine."

"It's gone."

"No. No, it's not. Not for me. 'Cos now it thinks I'm you." He threw the scanner onto a table.

"Are you insane!?" Elise yelled.

"Start the clock. Hello. I'm so pleased to finally see you. I'm the Doctor and I will be your victim this evening. Are you my mummy? But you can't hurt me until my time is up. I think. So are there magic words? Is there a way to stop you in your tracks? Oh, you really didn't like your gran, did you? There's something visible under the bandages. By the way, you weren't being paranoid. She really did poison your pony. Markings like the ones the scroll. Oh, and your father. Sorry. A tattered piece of cloth attached to a length of wood that you will kill for."

"Thirty seconds!" Elise called out.

"That doesn't sound like a scroll. That sounds like a flag! And if that sounds like a flag, if this is a flag, that means that you are a soldier, wounded in a forgotten war thousands of years ago. But they've worked on you, haven't they, son? They've filled you full of kit. State of the art phase camouflage, personal teleporter."

"Ten seconds."

"And all that tech inside you, it just won't let you die, will it? It won't let the war end. It just won't let you stop until the war is over. We surrender!"

"Zero."

The mummy appeared before their eyes.

Maisie gasped. "I can see it again."

The mummy stepped back from the Doctor.

"It's okay. I think we all can," Clara said.

"Do I start the clock?" the man asked.

"No," the Doctor said.

The mummy saluted the Doctor.

"The clock has stopped. You're relieved, soldier."

The mummy collapsed into a pile of dust and bandages.

"Phew. He's not the only one," the man said.

The Doctor picked up a piece of blue tech with wires attached to it.

"We were fighting that?" Clara asked.

"So was he."

"Listen, what I said..."

"Save it. We're not out of the woods yet. Well, Gus, I think we solved your little puzzle. Ancient soldier being driven by malfunctioning tech."

"Thank you so much for your efforts. They are greatly appreciated. Unfortunately, survivors of this exercise are not required."

The Doctor soniced the tech and grabbed a tool from another table. "Ah, well, there's a shocker."

People started to clutch at their throats, gasping.

"Air will now be removed from the entire train. We hope you have enjoyed your journey on the Orient Express."

"I take it you know a way out?" Clara asked.

"My enemy's enemy is my friend. Especially when he has a built-in teleporter," the Doctor said.

"Great! So use it!"

"A little more work." The Doctor fiddled with all the devices.

"Doctor!"

"Couple of minutes. Max. I'll give you a shout."

Clara hit the floor, out cold.

"Elise! Help me with this!"

Elise rushed to his side and helped him.

They teleported everyone off the Orient Express right before it exploded.
