"I thought of you two on Christmas Day. This Christmas just gone? Great big spaceship overhead. I thought, oh yeah, bet their up there" Sarah Jane says as the Doctor and I work on K9.
"Right on top of it, yeah" the Doctor replies nodding.
"And Rose?"
"She was there too" I say.
"Did I do something wrong, because you two never came back for me. You just dumped me."
"We told you. We were called back home and in those days humans weren't allowed" I say stopping to look at Sarah Jane.
"I waited for you both. I missed you."
"Oh, you didn't need us. You were getting on with your life" I say smiling.
"You two were my life. You know what the most difficult thing was? Coping with what happens next, or with what doesn't happen next. You both took me to the furthest reaches of the galaxy, you showed me supernovas, intergalactic battles, and then you just dropped me back on Earth. How could anything compare to that?"
"All those things you saw, do you want us to apologise for that?" The Doctor asks.
"No, but we get a taste of that splendour and then we have to go back."
"Look at you, you're investigating. You found that school. You're doing what we always did" I chuckle.
"You could have come back."
"We couldn't."
"Why not?" I put my head down and continue to work on K9 along with the Doctor "it wasn't Croydon. Where you dropped me off, that wasn't Croydon."
"Where was it?" I ask.
"Aberdeen."
"Right. That's next to Croydon, isn't it?" The Doctor asks, I screw in one more screw and suddenly K9 comes back to life.
"Oh, hey. Now we're in business" I move around the table.
"Master and Mistress"
"He recognises us" the Doctor says tapping my shoulder.
"Affirmative."
"Rose, give us the oil" Rose walks over handing me the oil.
"I wouldn't touch it, though. That dinner lady got all scorched."
"I'm no dinner lady. And I don't often say that" I say as I smear a sample on to K9's probe. "Here we go. Come on, boy. Here we go" I say whispering.
"Oil. Ex ex ex extract. Ana ana analysing."
"Listen to him, man. That's a voice" Mickey laughs.
"Careful. That's my dog" Sarah Jane says,
"Confirmation of analysis. Substance is Krillitane Oil."
"They're Krillitanes" I say.
"Is that bad?" Rose asks.
"Very. Think of how bad things could possibly be, and add another suitcase full of bad" I say gesturing with my hands.
"And what are Krillitanes?" Sarah Jane asks.
"They're a composite race. Just like your culture is a mixture of traditions from all sorts of countries, people you've invaded or have been invaded by. You've got bits of Viking, bits of France, bits of whatever. The Krillitanes are the same. An amalgam of the races they've conquered. But they take physical aspects as well. They cherry pick the best bits from the people they destroy. That's why we didn't recognise them" the Doctor says.
