(The Doctor is humming as he tweaks the Tardis controls. Door opens and closes.)

EVELYN: Good morning, Doctor. Good morning, Evelyn. I say, I like your new cardigan. Very fetching. Hmm. Well, I've made us some breakfast. It's nothing much, just some scrambled eggs, bacon, some toast, freshly brewed tea. Only took me a few minutes to rustle up. No bother at all. It's not as though it was your turn or anything. I keep meaning to ask you how the kitchen restocks itself. Every morning there are exactly six eggs and a fresh pint of milk in the fridge. And if I didn't know better, I'd say the bread was freshly baked too. You don't keep nipping out to the Co-Op when I'm asleep, do you? Doctor!

DOCTOR: Hmm? Oh. Oh, good morning, Evelyn. I say, I like your new cardigan. Very fetching.

EVELYN: Sometimes you amaze me.

DOCTOR: Oh, good. Because I stopped amazing myself two centuries ago. Sorry, I'm a bit distracted this morning. Ooo, tea. Lovely. Four sugars?

EVELYN: Of course. Just the way you like it.

(Drinks, smacks lips.)

EVELYN: What are you up to that's made you skip breakfast?

DOCTOR: Hmm? Oh er, just a few systems upgrades. Certain functions have been neglected over the years, disconnected. Thought I'd take the time to do a little, oh, housekeeping.

EVELYN: That's not like you. You'll do anything to put off doing repairs. Out with it. What aren't you telling me?

DOCTOR: Well, there are some functions that were included in all Tardises from the Type Zero onwards, at the command of Rassilon himself.

EVELYN: And you've suddenly discovered the need for one of those systems.
