Rose and the Doctor walked back to the TARDIS. They were in no hurry, and were enjoying a few last moments alone that they would get for a couple days.
They walked in, the Doctor holding the door open for Rose as she walked intentionally towards a certain part of the TARDIS console. "We'll need another room for Sarah Jane." Said Rose to the Doctor as she started configuring Sarah Jane's new room on the touch-sensitive screen. "I'm glad I took architecture my third year in high school... and for heaven's sake, Doctor, don't tell Sarah Jane that I'm a high school dropout."
"You know, I wasn't actually planning to." said the Doctor, sounding slightly offended by Rose's lack of trust in him.
"Yeah, I know, just thought I'd say." said Rose.
"Anyway..." said the Doctor. "We should probably get a move on. If I know Sarah Jane Smith, she's doing fifty on a thirty mile per hour street."
The Doctor played with some random controls on the TARDIS console. The TARDIS started to shake a little, and the Doctor got out his spare mallet, hitting the console dashboard with a loud clammer. He had a funny expression on his face, and Rose immediately got the impression that something was wrong.
"What is it, Doctor? What's bothering you? Is it Sarah Jane?"
"What? No, it's just... I'm afraid... well..." said the Doctor hesitating while trying to find the right words.
"Just tell me, Doctor, it's OK."
"Well, Sarah Jane's just a bit competitive, and so are you, and I'm just a bit worried that some earth shattering, literally earth shattering, catastrophe is going to happen, and you'll end up arguing over something like who saw more Daleks or something. Don't be offended or go off at me or anything, you told me to talk!"
Rose sniggered. "I'm not offended, Doctor. It's just like you to worry about me and Sarah Jane's bickering destroying the world. But... who knows. Maybe we'll save the world together." said Rose reassuringly.
Now it was the Doctor's turn to laugh. "I hope that's not some form of foreshadowing. What happens to me?" said the Doctor, laughing.
"Oh, I dunno, trapped by an evil spider, surrounded by crazy androids, something along those lines?" said Rose playfully.
"Yeah, how 'bout not. I'm not a fan of spiders or androids. And we've already done androids... and Ann Droids... I don't usually like to repeat myself. Unless it's Daleks, they're always fun." said the Doctor back.
They both felt the TARDIS jolt as they came to a stop in front of 13 Bannerman road. Rose and the Doctor both heard an odd sound, and looked toward the TARDIS door, which was mysteriously opening all on it's own, or so it seemed. Then Sarah Jane walked in with K-9 under her arm, and a funny sight they made.
Rose and the Doctor both stood mid-laugh by the console, mouths open and jaws dropped. "How...?" said the Doctor, speechless."
"You," said Sarah Jane, "never took the TARDIS key back when you dropped me off in Aberdeen." She gave the Doctor a look saying You know what you did, now let's just leave it. like older people can do really well.
"Yeah, maybe it's better if you don't just walk in. I thought we were being attacked by evil spiders who evolved hands and fingers and thumbs!" said the Doctor, still rather speechless.
Rose pushed a button, and Sarah Jane's room constructed itself instantly with a loud vworp!. "Um," said Rose, "your room's the third on the left down the hall on the right." Rose pointed in the direction of the hall.
"Thank you Rose." said Sarah Jane.
"And the wardrobe is... well... you know where, but the Doctor had the clothes from different periods all mixed up, and so I rearranged all of the clothes by date. I'll show you." said Rose, throwing a sidelong glance at the Doctor as Sarah Jane led the way.
The Doctor was just realising that this might be a very long few days.
