There is always someone who wants to die. Sometimes, they want to do it in secret, accidentally-on-purpose overdose themselves by a few pills, a few drops. Maybe a cut, painful, something that can't be reversed. Other times, they want something bold- jumping from a building, perhaps.

No matter what situation those people are in, I am there to help, whether they want it or not, ever since 1542.

"Mum, what's this?" I ask, holding up a pile of worn parchment. Mum storms over, snatching it out of my hands.
"You haven't read it, have you?"
"Of course not. It's just, Luke said-"
"Luke said what? Come on, Emma. Spit it out."
"I think he looked through that."
"Well, this is private. I'll have to tell Luke not to look through my things."
"He said something that made Jack and I worried." Mum grabs my wrist, and I stop in agony. Immediately, she releases me.
"I need to talk to you in private."
"My room," I agree.

When we get there, Mum shuts the door. "I didn't want Luke to find out about this because I thought he would take this the wrong way."
"Why did you start killing?"
"My girlfriend was killed in 1542. Ever since then, I wanted to help others. If they wanted to end their lives, I would try to talk them out of it, make them live longer. However, if I couldn't do this, I would work and help them die painlessly and privately. Usually, they would ask me to kill them. I wouldn't kill them if they didn't permit me."
"How many people died because of you?"
"At least a thousand. I'm not proud of what I did."
"Why did it end on the 12th May 1951? What happened then?"
"Sarah Jane Smith."

"Did I hear someone say my name?" Mummy asks.
"How long have you been standing there?"
"Long enough," Mummy walks in. "Ruby, why didn't you tell me?"
"I didn't want to worry you." As Mummy sits down on the bed, Mum pulls her into a hug.
"Luke's worried that you'll start killing again," I whisper. Mum looks at me, concerned.

"While Luke was with the Bane, their leader, Mrs Wormwood, fed him dangerous lies about what's going on and what's going to happen," Mummy explains. "She didn't say anything bad about me, but it was all aimed at Ruby."
"Why would she do something like this?"
"That's what we're trying to figure out," Mum insists. "If Mrs Wormwood never kidnapped Luke, we wouldn't be in this mess."

When Mummy leaves again to check in on the adults who recently arrived, I ask Mum a question I desperately want to be answered. "Are you going to kill again?"
"Only to protect my family. Now, you've got a team to run. You are kind, caring, and a great leader. Those are the qualities Jack was looking for. Rani, Clyde and Maria are new; they need someone to show them how things are run here. You are a great leader, and I couldn't be prouder of you." She pulls me into a hug, and I hug her back.

Someone knocks on the door. "Come in!" I call. Luke is standing there, looking a bit nervous. I sigh, a little annoyed. "What is it?"
"Clyde, Rani and Maria have found something on the monitors. They don't know what it is, so they want you to check it out." I jump up, smiling.

"I think Mum's coming onto you," I whisper.
"I know," Luke agrees. "I asked Mummy, and she knew about what Mum is. She doesn't seem scared."
"Mum promised that she'd only kill to protect her family- us."
"Maybe I was jumping to my own conclusions," Luke agrees. "Let's not worry about it." We walk into the central hub where Maria, Clyde and Rani are standing around a monitor.
"What have you got?" I ask.

"A meteor crash-landing," Clyde replies. "Jack wants us to get onto the case. He's coming with us to make sure that we can get in as the amateurs are already there."
"Let's go!" I grab my coat, smiling. I tell Jack where we're going, who accompanies us.

We get to work on the meteor to discover where it came from when Rani accidentally chucks a tool, which lodges itself in the meteorite. Gas begins to swirl around it. "Gas masks!" Jack yells, throwing us all one. A pink and purple gas rises out of the meteor before shooting off into the sky.

"That was a sex gas," Jack explains as we drive back.
"Another one?" I moan.
"What does a sex gas do?" Maria asks. Jack explains that it causes men to orgasm before killing them, using the energy to keep it alive.
"We need to find whoever it has taken for a host."
"The last one worked at a fertility bank. It could be linked."

"SEX GAS!" Clyde yells, pointing.
"I see it!" Jack exclaims, pushing his foot hard on the gas pedal.
"Who would have thought we would be chasing after a gas," Rani laughs.
"A gas with a sex drive that kills others," Jack agrees as he swerves around a corner.
"Watch your driving, boss!" I exclaim.
"Cheeky girl!"
"Sorry!" We run out of the car when the gas stops in front of a woman- the Doctor.

"Doctor, look out!" I exclaim. Too late. The sex gas encloses around the Doctor before she is forced to breathe it in.
"Luke, Clyde, come back with me to the car," Jack exclaims. "Ladies, I'm sorry, but I have to leave this with you."
"What? Jack!" Rani exclaims.
"Don't you remember what he told you?" I demand. "The sex gas can kill him, Luke and Clyde. We're on our own."

"Hey, Emma," the Doctor smiles.
"Hey," I smile back. "We need to take you in for questioning."
"Right," the Doctor agrees. I force her into the front seat because I can't trust her near the boys with that gas in her.

When I lock her in one of the cells, I begin to question her. "Emma, the gas, I don't know how I can stop it. It needs sex, but if I give it what it wants, it will make me kill. I don't know what to do."
"Do it with me."
"What?"
"Doctor, are we going to have this argument or not? Human-Qetesh hybrids can survive."
"You don't know me yet."
"I trust you. I don't know why I just do."
"Okay," the Doctor agrees as I unlock her cell and stand in front of her. "I don't think the wall will be too comfortable."
"No," I agree.

The Doctor sits beside me on the single bed in the cell. "Would having some music on help you calm down a little?" She asks, pulling an mp3 out of her pocket when she notices how pale I am. My breathing becomes inconsistent. It takes nearly all of my energy to nod. The Doctor plays some soft, calming music. "If there's something that you don't like, tell me, and I'll stop, okay?"
"Okay," I smile. I feel a little more secure. The Doctor gently begins kissing me, taking her time. I start kissing her back, feeling comfortable.

When the Doctor removes my top and begins to stroke my body, I feel at ease. Her touch is gentle; she's making sure I'm happy with it. Slowly, the Doctor begins removing her clothes, and I spot an earring she's wearing- an ear cuff with the top symbolising eight stars and the bottom in the shape of two hands holding each other- her love for the stars and how she prefers friendship and defeating enemies weaponless. The Doctor catches me admiring them and asks me if I like it, to which I agree. She looks a little shifty. "What's wrong?" I ask.
"I know I'm not meant to say this, but I'm used to having sex with you when you're older."
"How old?"
"You know I can't reveal that! It makes me a bit nervous that I have to do it with you at this age."
"Don't be," I smile. "I'm still the same person- or I should be." The Doctor laughs. "Besides, it's to save you. I'm sure that my older version will understand."

"We're going to have to go all the way this time," she tells me, gently.
"Okay," I agree, lightly.
"You're already going through puberty."
"I started two years ago."
"You might have your period soon. I wouldn't know about it; you'll have to talk to one of your mum's about it. You okay?"
"Keep going," I beg her, closing my eyes, letting the music surround me.

"You okay?" she asks.
"That was the best," I smile, closing my eyes.
"Well, you'll want to get some sleep," she tells me. "You must feel tired after all that excitement." I want to point out that I think I can keep going, but I yawn. "You need your sleep. Come on, bed!" We retrieve our clothes. I pull mine on before I leave the cell and shut the door. A piece of plastic is now separating us.

Jack calls me into his office a few minutes later. "What were you thinking, Emma? You know, when she…?" His voice trails off. I don't think he wants to use the word 'sex' around me, even though the Doctor did- twice.
"I wanted to help her, and I wanted to do it. She made sure I was happy and comfortable."
"Well, that's saying something," Jack agrees. "Water?"
"Yes, please."

Before I return to my room, I go to check on the Doctor. Luke is standing by her cell. The Doctor is still in there, tense. She relaxes when I walk through. "See? I told you your sister's fine."
"Yeah, you don't need to tell me," Luke agrees. "You okay?"
"Fine," I smile. "How are things going here?"
"We're going to try and expel the sex gas from her," Luke explains.
"Let's do this," I agree, unlocking the Doctor's cell. "Leave her," I command the sex gas. It leaves the Doctor at once, and Luke encases it in an inflatable cell as Rani, Clyde and Maria run in. The sex gas dies as we watch.

"At least no one was killed this time," I smile. "That's one pro from this."
"Yeah," Clyde agrees. "Thank goodness for that."
"Everyone okay?" The Doctor asks.
"Yeah," we all chorus.
"Good. Now, I need to be getting back to my TARDIS." I feel my smile fall.
"You're not staying?"
"I'm sorry, Emma, but I've got other stuff to do. However, I will see you all as soon as possible, okay?" We nod, and I drive the Doctor to her destination. "Bye, Emma," she smiles.
"Bye Doctor, until the next time." The Doctor nods before stepping inside her TARDIS, disappearing.
