Thank you Akihiro1997 for always reviewing, as to your point on the last chapter, I don't know much about pregnancy so sorry about the timings being wrong, I'll go back when I get chance and change the timings slightly so that it still works.

Please let me know what you think.

So without further ado, here is the last chapter.

Chapter 4

Bill's POV

We go into the familiar console room and she starts her up. We are thrown around as she flies the T.A.R.D.I.S to wherever it is she's taking me.

"I'll wait here." She says. "Come back when you're ready, but take as long as you need." I step out, wondering what she means. I go out and realise I'm in a storage cupboard, I get out and am in a long corridor. I look up and down, wondering where the Doctor has brought me.

"Lost?" Someone asks, coming out of a door opposite me. "Oh, you must be here to see Rosie Potts." She says, looking at me properly. "You two look very alike, you a relative?" I nod, and she holds the door open for me to go in. "She's on the bed at the end."

"Excuse me, what date is it?" I ask her. She gives me a funny look.

"16th July 1991." She says. I swallow. I know why the Doctor has bought me here.

"Thank you." I say and walk through the hospital ward to the bed that, according to the clock on the wall, my mum will die on in 7 minutes. I walk over, she's got her eyes closed, but she's holding a baby wrapped up in a blanket that is sleeping. A nurse is monitoring her.

"Mum?" I whisper, sitting down on the plastic chair near the bed. She opens her eyes and looks at me.

"Bill?" She says. "I understand why I'm not there for you any more." She winces as she holds out the baby for me to hold. "Could you take her for me?"

"I think it might create a paradox if I touched her." I say. "Sorry."

"It's not you who should be sorry. Lucas left after I was diagnosed, he couldn't cope. Who's going to look after you now?" She asks.

"I cope." I say. "I get put in care and am fostered almost straight away by a woman called Moira. I grow up wondering what it would be like to have a real Mum and one day I meet a crazy time travelling alien and we go on adventures together."

"Not exactly a normal life." Mum smiles.

"Who likes normal?" I grin.

"Exactly, normal is boring." She looks across at the heart monitor near her. "They say I haven't got much longer left to live. They asked if I had any last requests, so I asked for them to bring me you. I wanted to make sure you were here. I wanted to see you as I died."

"Well now you get to see two of us." She smiles weakly.

"True. Do you know how much longer I have?" She asks. I look at the clock.

"Three minutes." I reply. A tear trickles down her cheek.

"There's so much more I want to tell you."

"You don't need to." I say. "I already know what you need to say."

"You're such a strong girl." She says. "My little baby."

"I love you Mum." I say.

"There's not much time so listen up. You and the Doctor fell out, I can tell, don't deny it. She bought you to see me as a way of showing how much she misses you."

"Mum you're dying, haven't you got more important things to talk about." I don't want to upset her.

"What's more important than my baby's happiness?" She asks.

"I'm not a baby any more Mum."

"I guess not. But honey, people mess up. I mess up, you mess up, time travelling aliens from outer space mess up."

"You can't be from space. You can be from a planet in space, but not from space." I say, repeating what the Doctor told me once. Mum smiles. I made Mum smile, in her dying moments, I made her smile.

"Forgive her." She says. "She's got old eyes. She's seen a lot, I can tell. Don't waste a friendship on one mistake. Promise me Bill."

"I promise." I say. The line on her heart monitor is starting to get more irregular.

"I love you," She says, as I start to cry. "Don't cry. You have nothing to be sorry for. It's my fault. I'm sorry I was never there. I'm sorry you're going to have to have conversations with an imaginary mum. I'm so sorry. I've never been more sorry, but I can't do anything. If I could, I would, but all our days are numbered, and this is my end. Remember I love you always, always and completely, Bill Potts, my baby girl." She reaches for my hand and I take hers and stroke it, and together we both say the same thing in synchronisation.

"I love you." The line on the monitor stays still. I collapse in the Doctor's arms a few minutes later. This is all too much for me.

"Thank you." I whisper. "Thank you." She helps me over to a seat and I sit down.

"You okay?" She asks after a few minutes. I nod.

"I needed to be there." I whisper. I don't know how long we stay like that, her sitting next to me while I cry, but I eventually stop. "I never really knew what I missed out on before. Thank you."

"I'll take you back now." She says, getting up. My mum's words echo in my head. People mess up.

"Wait." I say. "Couldn't we make a few stops on the way back?" I ask. At this very moment my dad is getting a phone call from the hospital that my mum has died. He left my mum when she was diagnosed because he didn't want to get hurt. He knew from the start she wasn't going to survive. He loved her too much so he left her. They didn't get divorced, they just led separate lives. They were only married a few months. They married soon after they found out I was on the way. It was pretty rushed. They had been dating for years before then though.

The phone call that my dad is just about to get is what kills him. He loved my mum so much that he can't live without her in the end. Despite leaving her. He goes to the nearest multi-storey car park and jumps off. Leaving a 6 month old girl as an orphan.

The Doctor turns around and smiles at me. Mum wanted me to travel with her. She's right, I shouldn't ruin a friendship because of a mistake. We've wasted enough time these last six months. Maybe we needed them though. They say time is the best healer. But right now, I've finished healing. I'm ready to travel again. My mum helped me see that. She would have loved this life. So I'm going to travel with the Doctor. We may argue, but people mess up. And that's okay. People may mess up, but people also heal.

What did you think? I'm not sure if I will write another story around this storyline with adventures with Bill and the 13th doctor, certainly not in the next 6 months or so if I do because I have exams this year so I have less time to write fanfiction, but I might eventually come back to it.

There may be some differences between the TV series regarding Bill's family, but that was because I had to make it up because there wasn't a lot of information.

Thank you for reading.
