A phone booth appears in his cell. 

A man leans out of the phone booth.

"Hey, Mr. Mass Murderer, get in."

...okay that's the Master. Fuck.

"I'm not supposed to go places with strange men. Unless you have lollies."

"I have hundreds of lollies and chocolate too."

"...I do really like chocolate."

He really doesn't want to do this, but he has his orders. He wants to stay here in his cell and continue his brooding. He was really getting the knack of it. Practice makes perfect. But.

"These cuffs will kill me if I leave my cell."

"Hold very still."

The Master pulls out a laser and turns it to its highest setting.

It cuts through the cuffs as easily as butter. It will cut through Titus too, if he so much as twitches. 

Amy knows what is it, but turns around to show him the cuffs anyway without complaint. He doesn't move, but really, whats the worst he can do? Killing him would probably be a step up for the universe.

The Master slices through the cuffs with almost perfect precision. Titus's left wrist is left with a slight, instantly cauterized, gash. 

"Come on!" he says, jumping back into the TARDIS. 

Amy Titus leaves Stormcage and steps into the TARDIS.

He's never actually been in one before... it's nothing like he imagined.

The central chamber of the TARDIS is a large dome, paneled in woods of varying shades.

In the center of the dome is a circular panel of instruments. 

In the center of the instruments, there is a column of what looks like pulsing amber. It extends into the floor and all the way to the ceiling. 

There is a single, closed door in the wall. 

The Master goes directly to the console and enters something. 

"Now, we are nowhere," he says cheerfully.

"Nowhere is still somewhere."

"Does an empty universe count?"

"Less opportunity for me to fuck shit up, I suppose."

"But, on to the important thing. What are you? Who are you? Where are you from?"

"...you don't know?"

He starts laughing.

"What? What don't I know?"

"You seemed pretty up to date on my casualty list. But. Nothing else?"

"Everything in your file was redacted!"

"I'm right here in front of you, and you still can't tell?"

"You're not a time lord, but you're something. Which turns this from a brief jaunt to satisfy my curiosity into something much more pressing. Who are you?"

"I'm the Ultraviolet Catastrophe. I've killed more than five hundred thousand people all over time and space. Ripped them completely out of existence. I'm a murderer. You're a murderer too, aren't you?"

"Yes, I'm a murderer. Congratulations. You win a prize. Who are you?"

"My name is Amarillo Titus Song."

"Who?"

"Eldest child of Melody Pond and the Doctor."

"Really?"

"You're the Master. Lying to you is a really bad idea."

The Master puts a hand to his chest.

"You know who I am? I'm flattered."

"You name is written in the stars all throughout history. Of course I know who you are."

"So, tell me, why did the Doctor's son become a mass murderer?"

"I was raised by my adoptive mother. She doesn't much like the Doctor."

"I can't blame her. He killed our entire species, you know? Well, you've still got the humans, if they count. They don't count."

"...no?"

"Have you ever met humans?"

"No, the Time-Lords aren't dead."

"Yes they are. Have you tried to get to Gallifrey recently?"

"The fact that it's trapped in a pocket dimension would make that especially difficult."

"Trapped in a pocket dimension?"

He pauses.

"When did you last meet the Doctor?"

"The day he sent me back into hell."

"He sent you to the Void?"

"No, Gallifrey, right before the end of the war."

"How did you escape?"

"I'll give you three guesses."

He leans back against the console of the TARDIS.

"You stole a TARDIS and escaped?"

"Close enough."

"That seems.. fine then. The timeline seems to line up if we're talking about the same confrontation with the time-lords. This was his eleventh regeneration? Tall bloke, big hair?"

He shrugs.

"I didn't bother counting."

"You seem pretty caught up. He regenerated again, his last one. And now he's about to fuck up the universe."

He shrugs.

"There are plenty of other universes."

"You really think that when the Great Time War resumes it will restrict itself to just the one universe?"

"Resumes? Gallifrey. Is. Gone."

"The Doctor froze it in time, sent it out of the universe and to another dimension."

"Which dimension?"

"A pocket dimension. We know it's somehow connected to a human colony planet called Trenzalore in the Emphidian Reach."

"Can you find it?"

He isn't talking to Titus.

He shakes is head.

"If no one can get to them, they're as good as dead."

"Have you heard of the Siege of Trenzalore? A lot of people are trying to get to them- to the Doctor. Kill him and they never return."

His head starts to throb and he closes his eyes, trying to focus on something else. He grits his teeth.

"He's not an easy man to kill."

"Just gotta keep on trying then."

He does not look particularly enthused about this.

"Why? There are so many more interesting things to do."

"It's hard to focus on anything else. Mother doesn't like it when I resist."

"Mother?"

"Adoptive mother. She raised me." He pauses. "Do you have any tequila?"

"Yes. Lot's of tequila."

The Master opens the door in the side of the main chamber and heads into the hall on the other side.

He goes to follow but then pauses.

"You're okay with me being here?"

Titus doesn't really know the protocols when interacting with a TARDIS, but it never hurt him to be polite.

...well. Most times.

A bottle of tequila and a glass appear next to him, on the console.

...

"Thank you."

He takes the bottle, heads for the TARDIS door and opens it slightly, taking a peak outside.

Outside, there is only darkness.

Not really was he was hoping. Though the Master did say it was empty.

He sits down anyway and leans against the doorframe and sighs.

"Silence is it then," he mumbles and takes a long drink of the tequila.

The TARDIS moves. 

And he is staring at the surface of a blue gas giant.

A storm is raging, a swirl of dark red against the blue. It has been raging for a long time. 

As he watches it moves, slowly by any human estimate, but just fast enough to be appreciated.

It twists and it reaches,the edges of the storm extending, slowly overwriting more of the blue with bright tendrils of red.

He smiles wide.

"You really know how to show a guy a good time. I like you."

He takes another drink and just watches the storm. The pounding of his head is pushed to the side, he can ignore it- for now- and some of the tension leaves his body.

A minute or so later, he hears footsteps and the Master says, "Huh."

He sits down next to Titus with his own glass of tequila and a bowl of very cheesy nachos. 

Titus drinks straight from the bottle.

"Your TARDIS is really fucking great."

"She is, isn't she?"

"Did she bring you to me?"

"What, did you think I walked?"

He shakes his bottle at him.

"You know what I meant. Stormcage is very off the grid."

"No, sorry. I wanted a look at the big bad criminals and she obliged."

"And you decided to take one out on a field trip?"

"I didn't have anything better to do."

"You're going to have to take me back eventually. Or kill me."

"Why? There are a literally uncountable number of places nicer than that jail cell."

"Unless you have a way to stop me from killing the Doctor, Stormcage is my best bet."

"You hate him that much?"

"It's a compulsion, I can't control myself. Mother made sure of that."

"And who is this adoptive mother of yours?"

"The Great Madame Kovarian." He winces and takes a long drink of the tequila. "Mummy Dearest."

"Never heard of her."

"Have you heard of the Church of Silence from the 52nd century?"

"Nope."

"Well. They exist as a response to a prophecy about the Doctor. How he will bring back the Time Lords and restart the Great Time War. My mother formed her own chapter. Mission statement: kill the Doctor before he arrives at Trenzalore."

"Not doing a very good job of it, is she?"

"The Doctor is a hard person to kill. But that's why she has me. What better way to kill a Time Lord than to use another Time Lord?" He pauses. "If that's what I am."

"You're not," he says cheerfully.

"You're close, but you're not."

Titus shrugs and takes another swig.

"Figured. Never even met any other Time Lords. My mum is like me, though maybe less so. She had human parents."

"Why do they think they need a Time Lord to kill a Time Lord?"

"The Doctor travels all through time but isn't affected by it. They figure that's a Time Lord trait. Need someone similar, close enough, so they can do the same thing. Keep track of him."

"And what do you think?"

"Does it matter what I think? They've changed me enough that I can't control myself. Killing the Doctor is my mission."

"What've they done? Stuck tiny bombs in your hearts? Removed bits of your brain?"

"Spent my entire first regeneration rewiring my brain with psychic compulsions until all I could think about was killing the Doctor. It's a part of me now."

"They sound like arseholes."

"Huge arseholes."

"Why haven't you killed them yet?"

"Psychic shit stopping me. Plus they have a kill switch. I tried a couple of times."

"You know, lately I've been trying to have reasons before I murder people. That sounds like a pretty good reason to me."

"You need reasons to kill people now? Why?"

"I'm testing things out, seeing what works for me."

"Good luck with that. Feel free to kill them, then. Though they're probably the only thing stopping the Doctor from bringing back the War."

"Why is he doing that again?"

"His enemies seek Gallifrey's destruction. The siege lasts over nine-hundred years, a stalemate. He's on his last regeneration, so he can either die and his enemies will destroy Gallifrey, or he can set the Time-Lords free..."

"So you're saying, if I don't kill them, Gallifrey will be destroyed? Wow, I really don't want to kill them now. Not at all. It's not like I'm attached to my entire species or anything."

"The Siege is also occupied by the Daleks, Cybermen, the Weeping Angels... half the universe is in attendance."

"How exciting."

"You'd need a way to get in..." he looks outside and thinks, "Maybe some sort of multi-dimensional shifting device to get past the blockade... but you'd also need to have some way to stay in place. The whole time period is steeped in anti-TARDIS and Time Lord tech."

"Anti-TARDIS tech takes advantage of safeguards the TARDIS's built in safeguards. We don't have those anymore."

"That's handy. We still need to get past the blockade. I can build something, but if she can just do it herself?"

"Sure, if she's in the mood."

"Theres no rush. If she wants to take her time I could also build a temporal bomb... and if that bomb somehow disappeared and made it way into the Silences head quaters... well that's just out of my hands, isn't it?"

"I'm sure they'd never suspect you."

"The worst they can do is kill me and they've done that so much now that's it's kind of passé."

"How many regenerations do you have left?"

"Five. This is my seventh."

"Five. Five, four, three, two, one. You're over halfway done."

"Mother had to study regeneration somehow."

"It took seven tries. Not very clever, is she?"

"Four times. One time was all me, the other two was her punishing me for trying to kill her." He hums fondly. "Good times."

"Which part was it? The pain? The burning? The light?

"The burning. For a few blissful moments, everything is clear in my mind, no more compulsions and pounding. True silence."

"But never for quite long enough."

"No. But at least it's something to look forward to."

"Ever tried drugs?"

"What kind of drugs work on not-quite-Time Lords?"

"All of them. Not like they're supposed to, but they work."

"Sounds fun. I'll try everything at least thrice."

"There are plenty tucked away around here."

"Raincheck, for sure. Would appreciate more of this," he shakes his empty bottle of tequila, "maybe some cake and a pounding bass. I work better with all of those things. Bomb isn't going to build itself."

"Are you making the bomb out of cake and alcohol and music, or do you also need supplies?"

"I figured you'd have some sort of workshop and I'd wing it from there." He pauses. "That would make an interesting bomb though."

"I have a workshop. You are not going in my workshop."

"I don't really care where I am. Somewhere out of the way is probably ideal."

The Master gestures at the hallway.

"There are rooms. Pick one."

"I think I'd rather let her pick for me." He stands and walks over to the hallway. "I don't know how that would work, though."

"Every room you see is one she wants you to see."

Amy picks a door at random.

Inside, there is an olympic size swimming pool that stretches all the way to the walls. 

"You want me to go swimming? I don't think I know how," he says to the TARDIS.

There's no obvious response. 

Well then. He tries another door.

A kitchen and an attached, very well stocked, storeroom. 

Amy hasn't eaten proper food since... a really long time. Stormcage served only bland porridge-like nutrients.

He steps into the room and smiles.

"I think I love you."

The TARDIS doesn't respond. 

There are a lot of cakes in the pantry. There seems to be a food preservation effect. Nothing is sealed away.

He takes a few choice options and looks around for more alcohol.

The alcohol has its own corner. There's a decent selection, though nothing is particularly unusual or high quality. It's all things you could get in the average liquor store. 

He takes a couple of bottles of tequila.. and pauses.

"I would just like to note that I have spent the last three years in the most secure and boring prison in the universe. I have missed everything."

He smiles down at his haul.

-- and heads to find somewhere he can work.

One of the doors leads to a room with several long workbenches.

He looks around for the Master... was this the off limits workshop?

The tables are empty. There are no projects or material lying around. The space looks unused.
