"So. Where next?" The Doctor threw his coat over the railing and began his usual eager dance round the controls, putting the TARDIS into flight. Martha hid a grin; he was like a child sometimes. "We could visit the original New York if you'd like—"
He was cut off by the sound of a phone ringing. "Uh, Martha, could you get that? My hands are full."
"'Course, I'd quite like to see who on Earth phones you up." Martha picked up the phone. "Hello?"
"Hello, is that Jacqueline Tyler?"
Martha blinked. "Who is this?"
The man's answer left her stunned and bemused. "Sorry, I think you've got the wrong number."
"Who is it?" the Doctor asked, winding a length of string round the controls and putting it in his teeth.
"Something about a gas bill."
"Oh! Give it here." The Doctor quickly tied the string round one wrist and reached for the phone with his temporarily free hand. "Hello?" After a moment, he sighed. "No, I'm not Jacqueline Tyler—do I sound like I'm Jackie? Blimey, I hope not—No, but I'm handling her account now. Which you obviously didn't take note of last time you called."
So much for the Doctor not being domestic. Martha smothered a giggle as the Doctor got more annoyed with the caller.
"No, I'm not interested in reactivating the account. Why? Because the flat is empty, that's why. If the previous occupants come back to life and require gas again, I'll be sure to let you know." With some force he replaced the phone. "Humans."
Martha swallowed. Suddenly she didn't feel as much like laughing. She had just decided not to ask about what had happened, when the Doctor seemed to remember she was there and spoke again.
"Rose's old place. I had their calls redirected." It was a simple statement, spoken matter-of-factly, but his eyes darkened as he spoke. "Didn't have half this much trouble with the electricity company." He untied the string and moved over to a different set of controls, guiding the TARDIS more smoothly. "Oh, that reminds me. If you ever pick it up and it's one of those recorded 'you've won something' messages, press the mauve button."
"Why, what's it do?"
The Doctor just smiled, a mischievous twinkle coming back into his eyes. "Charges the caller the full local rate."
