Ring! Ring! Ring!

Clara goes out and leans on the side as she grabs the phone, "Hello?"

She passes the phone down, "Doctor! It's for you! A woman named Kate is calling you!"

He pulls it and Clara asks the Doctor from outside, "Where are we going?"

"Good question," he replies as he hangs on the sides on the Tardis, "Kate, where are we going?"

"We just experienced some trouble and I'm having you taken directly to the scene. We need your help to figure out what has happened," Kate explains as she walks in with UNIT soldiers.

"Hey! Hey you! Hang on, where you going?" Kate hears the blonde woman exclaim, "You can't walk off with that! That belongs to the museum!"

The woman walks up to Kate and points her finger at her, "You've no right in taking these pieces of art. How dare you rob it from the museum, are you even listening to me?"

She sighs as she covers the phone, "Ma'am this is strictly UNIT's business. We're trying to figure out what has happened."

"Are you the police?" she asks Kate and she answers, "No, we listen to a higher authority."

"Well, since you're not the cops and invading and suppressing my rights; I'm going to call the cops. I've got rights and you can't do this. They'll settle this," she walks away from Kate and she sighs again.

A UNIT soldier passes by Kate as she grabs him, "Can you take care of that woman? We don't want the public to be storming in here. Bad enough that we're here."

The soldier nods as she releases him and he walks after the distressed woman.

Kate goes back to the call, "Doctor...this is going to interest you greatly."

Few minutes...

Kate is outside waiting with the other soldiers as they look around the skies. A woman with black hair wearing a lab coat and glasses with a long scarf walks quickly up to her, "Ma'am, ma'am!"

Kate turns to the woman, "Yes Osgood? What is it?"

"We did a quick scan on the pictures and the glass; we figured the two are together ma'am. We don't know how though," she replies as she hands her the papers to Kate and gets a bit breathless.

Kate speaks as she reads the report, "Inhaler."

Osgood nods as she pulls out her inhaler and uses it.

"Are these readings right?" she asks Osgood, "Yeah, they are."

"Not possible," she speaks as she looks up at the sound of the roaring plane with the TARDIS gently descending.

She closes the reports and walks over to the soldiers.

"Atten-tion!" one soldier shouts as the others copy his action while the Doctor jumps from the TARDIS and lands on the ground.

The plane lowers the TARDIS and Clara walks off it. Both of them walk as the soldiers salute them. They meet up Kate and Osgood as they salute the Doctor and Clara with the Doctor saluting back.

He drops his hand as he speaks, "Wait a minute, why am I saluting?"

She walks back to the museum with Osgood and the other soldiers with the Doctor and Clara follows them. The Doctor and Clara reach up to Kate as she hands him the reports, "Doctor...read these readings and have an open mind of what you'll see."

He flips through the pages and turns them around as he walks on while following Kate and the soldiers with Clara behind him as he passes the reports to her.

She adds, "My deepest apologies of bringing you here, but we need someone of your caliber. Actually, only your expertise can help with this."

"Excuse me. Excuse me," they turn to see that same woman before.

She storms up to Kate and angrily vents, "How dare you keep me captive in my office. You should know that the law won't tolerant this."

"Who are you?" she asks the Doctor and Clara, "Are you working from the same injustice ruling as these people?"

"Hi, I'm Clara Oswald. Nice to meet you," Clara introduces as she shakes the woman's hand.

"I'm the Doctor," the Doctor states with a smile.

"What...those codes names?" she asks clearly irritated.

"No. And no, we're here to help," the Doctor explains as he snaps his fingers at her, "Um...what is your name?"

"My name is Rosemary Tylee," she states, "I guess you're here to see the injured people from the incident then doctor?"

"Glass incident?" the Doctor parrots confused.

"Not here," Kate said as she points to the museum, "Inside."

Rosemary, Clara and the Doctor went inside while Kate whispers to Osgood, "She called the cops and they demand the status of the situation. What's our cover story for this?"

"Um...Criss Angel?" Osgood offers and Kate replies, "Really? Again, that poor man."

"Well...we'll send him flowers on behalf of our apologies," Osgood comments.

Kate gives her a look and she changes it.

"How about...Um...A faulty gas line erupted and caused many people to get hurt and hallucinate?" Osgood retorts.

"I guess that'll work," Kate said as she nods to one of the officers and explain to the police the story, "Also, I want a secure perimeter around the gallery. Got it?"

He nods and leaves; Kate and Osgood follow the rest as they go into the museum.

Inside the museum...

Rosemary guides them to the a painting while the Doctor and Clara talk amongst themselves, "I wonder what happened here that they had to air lifted you here."

The Doctor replies, "It has to be serious. After all, that is why UNIT's here."

"What is UNIT?" Clara asks as the Doctor states, "The name means Unified Intelligence Task Force."

"Sorry, what are they? Who are they?" she asks.

"UNIT. This-this lot here. They are a military organization. They investigate alien stuff. Anything alien. Anything at all of alien origin," he answers quietly.

"Like you? Did they study you?" she asks him.

"No, I work for them. In fact on a few things with them," he replies.

"Wait...You have a job? Since when did you have a job?" she questions him sounding shocked.

"Oi! Why shouldn't I have a job? I'd be brilliant at having a job. I'd be the best employee or boss or CEO. Something," he protests.

"So you don't really have a job then do you," she states.

"I do too. In fact, this is my job. I'm doing it now. I'm trying to investigate the museum's mystery," he claims.

"No, that's a favor you're doing. You never have a job," she speaks and he stops to face her, "I do so."

She crosses her arms as she asks, "Name one then?"

"Well...um...I do," he retorts.

She smiles as he replies, "Shut up."

He turns back to follow Rosemary with Clara following behind them.

"This painting here was found near the Queen's castle and was kept under lock and key for many years," Rosemary explains as she pulls the sheet and reveals it as an alien Citadel on fire and under attack.

The Doctor and Clara were astonished by this as Rosemary continues speaking, "It was found after two strangers saved her. Legend says that after the two people left; she found this in a cave and took it away so no one could ever find it. So no one would ever figure out its secrets."

Clara shakes her head, "But, but that's not possible. How?"

Rosemary sighs, "The thing is we don't know the name of this piece."

"I know the title," the Doctor replies as both Rosemary and Clara look at him, "No more."

"That's the title?" Rosemary asks him as he nods.

Rosemary touches the frame and comments, "People long ago thought it was the Fall of Asgard. The Fall of something because of the picture clearly states that."

"There was a piece of parchment with this piece, but it is no longer legible. It is right across it," she points to the display, "It is written in a weird language of unknown origin."

The Doctor takes out his sonic and scans the display, then reads the information. "It's Gallifreyan. The language of my people and it says, 'Gallifrey Falls.' Gallifrey, such a beautiful place. A wonderous place."

"Doctor," Clara asks him, "How can this be?"

"It can't," he states as he pockets his sonic screwdriver, "This painting doesn't belong here, not in this time or place."

"Obviously," Clara counters still shocked at the picture.

Rosemary asks completely lost, "What are you two talking about?"

"I'm an alien and this art piece is of my home," the Doctor explains, "Gallifrey. This is showing the fall of Arcadia, Gallifrey's second city."

"You mean...this really isn't from here? From Earth?" Rosemary asks as she pulls her hand away from the frame.

Clara walks closer to it, "But how is it doing that? How is that possible? It's an oil painting in 3D."

The Doctor states, "Just like anything from the Time Lords. This is Time Lord art. Bigger on the inside. A slice of real time, capture...stuck...preserve...frozen."

Clara takes the Doctor's hand, "You okay?"

The Doctor replies, "He was there."

She turns to him, "Who was?"

The Doctor takes a deep inhale, "Me. The other me. The one I don't talk about. The one I never talk about."

Rosemary comments, "Wait a minute I don't get."

"I don't understand it either," Clara adds.

He points out the man in the picture, "Right there. In the center of it all."

"You don't get it. I've had many faces, many lives. I don't admit to all of them. There's one life I've tried very hard to forget. I tried to erase from my mind. He was the Doctor who fought in the Time War, and that was the day he did it. The day I did it. The day he killed them all. The last day of the Time War. The war to end all wars between my people and the Daleks. And in that battle there was a man with more blood on his hands than any other, a man who would commit a crime that would silence the universe. And that man was me," the Doctor explains.

She asks him, "But the Time War's over. So why is this here?"

"Good question," the Doctor replies.

"We've more art pieces found with this one," Rosemary comments.

Clara turns to her, "Why have you brought us here to look at a painting?"

"These are the reason we brought you here," Kate explains as she walks with Osgood.

"The painting only serves as Elizabeth's credentials about the seriousness on the matters," she adds.

"So when you brought me here. It wasn't because of just the glass incident; it was a request from her wasn't it," the Doctor comments.

Kate explains, "I'm acting on strict and direct instructions from the throne. Sealed orders from her Majesty, Queen Elizabeth the First."

"Wait a minute here," Clara speaks as she pulls her hand from the Doctor's, "The Queen? As in the First? Sorry, Elizabeth the First? Queen Elizabeth the First?"

Kate nods as Clara looks to the Doctor and he smirks, "What?"

"You never told me?" She asks.

"Um...yeah, it is a little blurry actually," he comments as he tries to think.

"Anyway, what does the Queen want with us?" he asks Kate.

She hands him an envelope, "Read this and you'll understand."

He quickly reads the letter and is shocked at the end, "Wha-What? But...What?"

Clara takes the letter and reads it aloud, "My dearest love, I hope the painting known as 'Gallifrey Falls' will serve as proof that it is your Elizabeth who writes to you now. You will recall that you pledged yourself to the safety of my kingdom. In this capacity I have appointed you as curator of the Under Gallery, where deadly danger to England is locked away. Should any disturbance occur within its walls, it is my wish that you be summoned. God speed, gently husband."

She turns to him, "Husband?"

"What...it's time travel, nothing happens in the right order for me. I can't help that," he states.

He turns to Kate, "What happened?"

She replies, "Easier to show you than to explain."

"Osgood!" the woman turns to find a man in a lab coat walking up to her, "Here's some more reports about..."

He stop speaking as he see the Doctor, "Is that him? Is that the Doctor?"

Osgood nods, "Yeah, that's him alright."

"Blimey, can't believe I get to meet the Doctor," he smiles as Osgood calls his name, "McGillop, now isn't the time to stand there idly. We've work to do."

She leaves while the Doctor and Clara leave with Kate and Rosemary. McGillop feels his phone vibrate and answers his phone, "McGillop. But that's not possible. I was just. Understood, sir. But why would I take it there?"

Kate takes them to a secret part of the museum.

"Step right through," she said while Rosemary comments, "But...it's just a wall."

"Or is it?" Kate speaks as she walks through, shocking Rosemary as the Doctor and Clara walk through it with Rosemary on their tails.

They all walk in as a metal shutter comes down behind them as they stand in front of a painting. The painting shows four people, but the Doctor knew three of them all too well.

Clara turns to the Doctor, "Elizabeth the First. You knew her, then?"

"A long time ago," the Doctor states stunned.
