The Curator stood outside 13 Paternoster Row. As Victorian London went about it's business behind him, he took a deep breath and approached the blue front door. He straightened his tie before knocking on the door. He listened and could hear heavy footsteps coming to the door. Moments later it opened and standing in front of the Curator was a Sontaran dressed as a butler. They both looked at each other for a few moments before the Sontaran spoke.

"What do you want?" he asked.

The Curator smiled, "I request an audience with Madame Vastra." he said.

The Sontaran looked at him for a moment, "Why?" he said simply.

"Because I have a matter of life and death to speak with her about."

The Sontaran sighed, "Very well come in. Should you make a scene or act incorrectly you will be obliterated."

"That sounds fair." The Curator replied with a smile.

The Sontaran was taken a back by this reply, "Who should I say wishes to speak with her."

"The Curator."

"Wait here." he said as he waddled off, muttering something under his breath as he walked.

The large hall way was immaculately kept. Newspaper cuttings in frames were hung on the walls. All detailing murderers being caught and unexplained things that had happened. A rack of impressive swords sat on top of a table too.

"Follow me, Madame Vastra will see you." the Sontaran said as he reappeared.

He led the Curator through the house to what seemed like a huge greenhouse which was attached to the back of the house. Madame Vastra sat in a large chair with a black veil covering her face. A young human woman standing to her left.

"Sit there Curator."

The Curator sat in the empty chair that faced Vastra.

"Strax here says that you need to speak to me about a life and death situation?"

"I do indeed Madame, thank you for agreeing to speak to me." The Curator replied.

"You don't seem phased by a Sontaran?" Vastra said.

"He's not the first one I've seen." The Curator replied.

While he could only just make out Vastra's eyes he could tell that piece of news intrigued her.

"Before we speak of your problem I must ask, what sort of name is The Curator? I'm starting to think you're not of this world." Vastra said.

The Curator smiled, "That would be correct." he paused for a moment, "The Curator is the name I chose for myself, much like the Doctor chose his."

There was an audible gasp from Vastra and the human woman.

"You're claiming to be a Time Lord? Impossible, they're all dead."

"That's what we want everyone to think. The Doctor wasn't the only one who escaped the Time War. Myself and eight others did too."

Vastra nodded to Strax and before the Curator could respond the Sontaran jabbed him with a syringe and took some of the Time Lord's DNA.

"Ouch." The Curator said.

"It's the only way for us to see if what you're saying is the truth." Vastra replied.

Strax walked over to Vastra and handed her the syringe. She looked at the small electronic readout screen on it before looking up.

"Why has the Doctor never mentioned you?" Vastra asked.

"Because he doesn't know we survived." The Curator replied, "And for now that's how it needs to stay. I know the three of you are friends of his and I need you not to tell him."

"Why?" Vastra replied.

"That's not important right now, I'll tell you another time, right now I need you to trust me and I need your help." the Curator said.

"Very well. Tell me what you need my help with."

"You killed Jack the Ripper?"

"Yes."

"Well he's back, or should I say a clone of him is in the year 3124. Someone, I don't yet know who has brought him back."

"And you need my help to stop him?"

"Yes. I travel with a human woman named Kara Grant."

Kara's name received a noticeable reaction from Strax.

"Yes Strax THE Kara Grant, it's another long story. He has her."

"Then I'm afraid Curator that she is dead." Vastra replied.

"No she's not. He has her captive. You see he has all of the real Jack's memories. He told me that unless I bring you to him, she will die."

Vastra lunged out of her chair and flew across to the Curator, her veil over her head now to reveal her Silurian features for the first time. The Curator didn't even flinch or leave her gaze.

"You want to give him me for her?" Vastra snarled.

The Curator nodded, "Yes and no. There's no way I would give you to him for him to kill you. But I need you to come with me to make him think that."

Vastra calmed down and took her chair again.

"You are very brave Time Lord. Surely he will be expecting you to double cross him?"

"That's where Strax and your lovely wife, hello Jenny, come into play. I'm guessing that he knows nothing about the two of you. While I take you to him, Strax and Jenny go and find Kara. Once she's safe, you can eat Jack the Ripper for a second time."

"And why would I take that risk?"

"Because if you don't Kara will die and when I seek vengeance, should I die before I can regenerate, so do all the other Time Lords, including your friend the Doctor."

"You place a lot of importance upon yourself."

"That's because I know the bigger picture. Madame Vastra I will beg you if I need too, but please come with me."

Vastra looked at The Curator as if trying to gauge him.

"Before I go anywhere with you I want to know why I shouldn't tell the Doctor about you and why your life is so important."

The Curator sighed and then gave in and began to tell her, "During the Time War I had a reputation for being able to get tricky missions done. At the end The President found out what the Doctor was planning to do. He summoned me for one last job. He asked me to kill the Doctor. My payment for doing this was the restriction on my regenerations was removed, I can regenerate an infinite amount of times. He gave me the payment up front. Of course I never had any intention of killing him. I went and found him and told him what I had been asked to do and to tell him that he needed to watch his back. In return he told me that he was going to end the Time War and I didn't have much time to escape. I went back to the unit I was part of and told them what was going to happen. The nine of us managed to escape just in time and we went our separate ways. Our commanding officer is called the Stationmaster, I owe him all my lives many times over. He has had his last regeneration, the next time he needs to regenerate he will simply die and I cannot let that happen. It turns out the Doctor didn't destroy our people as he thought for a very long time. He froze Gallifrey in a single moment and put it in a pocket universe. We managed to find it. There is a part of it where time continued and that is where we need to go."

"So why not tell him, he'll help!" Jenny said, speaking for the first time.

"If the Doctor finds out before we can get in there and he brings our home back, time will re-synch itself and I will lose my chance to get what I need. When I'm done then I'll tell him where it is as he is the only one who can bring it back.."

Vastra looked at him, deep in thought.

"Madame Vastra what would you do to keep those you cared about most alive and safe?" The Curator replied.

"Very well, I agree to all of your requests." Vastra replied.

"May I say something?" Strax asked.

"Of course." Vastra and the Curator both said in unison.

"If this is the Kara Grant you claim it to be, how do you think she will react to being rescued by a Sontaran?"

"That's why I would like Jenny to go with you. That way she'll know you're there to help her and she probably won't try to kill you." the Curator replied.

"Probably?!" Strax exclaimed. "I'll get the grenades!"
