They followed Sophie to the kitchen and Doctor started taking readings with his sonic screwdriver.
-So – the child started. – You never introduced yourself. I'm Sophie and you are…?
-Professor Song. Archeology.
- Hmm archeologists are fine but professor is not a name, right? I know there is a Doctor but his name is a secret. Is your name secret too?
-No, it's not. My parents named me Melody Pond, but I'm professor so I introduce myself as one..
-Wait a minute! You just said Pond and before you said Song? Are you a lair? I don't like them. They lie all the time.
-Well Pond it's my mother maiden name. I use it from time to time but people mostly know me as professor Song, and again why I'm even explaining myself.
Doctor crouched down next to girl and said in mock whisper:
-It's her new way of being. She tries to explain herself on every step. It clearly is a brand new Ri…
Doctor paused and straightened himself ending quickly to mask his slip.
-Risotto is famishing especially on the Moon, especially in 34th century. Have you ever tried it? No? Only me? What a shame! We should go there then, or better stay inside the TARDIS, the fumes. Do you think they deliver?
Sophie looked at him like he just grew himself a second head but she was also a bit curious about it all. River only rolled her eyes. After so many years she was used to Doctor and his way of being.
After a second girl smiled widely and said.
- Please, don't take it wrong Doctor but I think you are a bit crazy.
River coughed at that and it kind of sounded like 'only a bit?' but Doctor decided to ignore it and instead he said mostly to his wife
-Well do you want to hear something really crazy? In that kitchen Time Lord regenerated about from 5 to 16 hours ago.
-But it was white light, not the orange one! – Sophie protested. – I'm not a baby anymore. I know how regeneration looks like.
-Should I bother asking where 4 year old can watch regenerations to recognize one later?
-Rorre Ri… Melody. Rorre. Things like this happens here.
Girl who was feed up with grown-ups talk asked impatiently
-So are we going to look for her or what?
-Yes. We are. You… Well you don't.
-But I have to…!
-Doctor, we can't leave her on her own she's still a child.
-Oh come on. We will get back in the exact…
-How? You didn't bring us here who knows if we will be able to come here again. And besides you never make it on time.
-I'm always where and when I need to be, thank you very much.
-If you say so sweetie, but if we manage to get back I will be a bloody miracle and I'm not sure if I believe in them. – With that she ended their talk and then she focused on Sophie – Come on kid . It's time for your big adventure. But first, when did you eat?
-Who has time to eat if there are other things to do, worlds to save, places to see and adventures to have? So where are we going?
Doctor was about to respond her but River was faster this time.
-I need to talk with somebody who might be able to understand what's happening.
-Understand what? – Doctor asked – And who could know? I mean beside me, not that I know of course… but how could I?
-Dorium. He knows a lot. He might know how she same here and why. She doesn't have any regeneration energy left. There isn't any black hole near so she is from this reality and we both know that it seems impossible.
Sophie who was busy touching the console with fear and excitement stopped. She looked at them with shock written all over her face.
-Do you know River?
-Yes. As a matter of fact I do know her very well. She killed me. Twice.
-What do you mean by "killed you"? You are standing here and you are alive.
-Spoilers. Why Dorium?
- Maybe he will know why she appeared here. How she even managed to. You know, he hears stuff.
Child interrupted them again
-Why do you keep saying it like it was something hard to do?
-Well… isn't it?
-Nope. You are both here.
-It's… It's complicated.
-So is life Doctor.
-You know young one, you are too cleaver for your own good. You may make yourself some enemies with attitude like that.
- Like you did Doctor?
At that River laughed and he was so taken aback with it he forgot to make some sort of cleaver comeback at the kid. In his timeline it was 173 years 4 months and 3 days since he last heard her laugh. And he had no idea how he could have lived without it before. But if he will admit it, River without doubt would call him sentimental idiot. So it's better to play it safe. He will pretend to be offended for that opinion. Even if she might be right.
-Oh you are as horrible as she is. – saying that he pointed at his wife and asked her - Why have I even agreed to this?
-You had no choice. You were over voted. 3 to 1 and you know it.
-Sometimes I really hate you.
-No. You don't.
