Chapter 1.

"Oi, Doctor, I'm tired of trouble. Let's take a vacation." Sadie said looking up from her book she was reading.

"Are you alright? Are you drunk, sick, and perhaps got a bite by a Juragnut?" The Doctor asked, taking her pulse.

"Oi! I'm perfectly fine. I just wanted to visit my sister without trouble." Sadie said, smacking the Doctor's hand away.

"Oh. Okay. But I can't promise you any trouble, because troubles always seem to follow you." The Doctor called from across the console of the TARDIS. Sadie rolled her eyes and said, "My sister lives in Washington D.C at um…oh I forget."

"Maybe you should try sonic-ing your brain." The Doctor teased.

Sadie ignored the Doctor and said, "Allons-y?"

"Allons-y!" the Doctor mimicked.

(a/n: Yeah, I know it's so short. I'll try not to let the others be this short.)

Ziva, for the last time, there's nothing here! Let's just go back-"

"To Gibbs and lie to him? Tony, I will not disobey orders." Ziva snapped angrily at Tony. Before Tony could argue further, they heard a strange noise, and in a blink of an eye, a blue, 1950's style public police call box appeared out of nowhere.

"Guard." Ziva muttered out of the side of her mouth. They heard voices inside the strange box.

"So…we find your sister, say hullo, find my friend, say hullo, and chill? Allons-y?"

"Oh my god you're obsessed with that word, but yes. I prefer 'Geronimo.'"

As soon as the Doctor opened the door, a man shouted, "NCIS! Hands up!" Sadie followed the Doctor's suit and put her hands up.

'The man spoke, "I'm Tony and this is my partner, Ziva. We're patrolling this area and you are to come with us."

The Doctor said, "I'm the Doctor and this is my friend, Sadie."

"Doctor? Doctor who?" Ziva asked.

"John Smith. Referred as the Doctor. Oh, and, Sadie, I believe you owe me 15 quid. I told ya, trouble always finds you…"

"Oh, shut up, you git. I give you an IOU. All my money is in the TA-car." Sadie said, poking her tongue at the Doctor as they walked to the car.

After a little in the car, Tony said, "So why are you two here in America?"

"Weeell, we were supposed to be visiting friends." The Doctor replied.

"And do you know anything about the airport?" Ziva asked.

"Um…it's an airport?" Sadie answered.

"Well, yes, but is there a significance about the airport?" Ziva asked again.

"Um…it's big?" Sadie tried again.

"Ziva, look Ii really don't think they know about it, so just leave it to the bossman." Tony said glancing up from the road.

"Fine," Ziva said, "so you are from the United Kingdom, yes?"

"Yep!" The Doctor replied popping the 'p'.

"You're er, hang on a sec, Israelian, right? And Tony's Italian, correct?" Sadie asked. Tony exchanged a brief glance.

"Yes," Ziva replied, "how did you know?"

This time the Doctor answered, "You have the Israelian accent and Tony's got the hair."

"Oh-ho! I like this guy. See, Ziva, hair is an important part of our Italian trait, yeah?" Tony said with an Italian accent. Ziva rolled her eyes as a smile threatened to break out.
