He led them on to the Tardis and started inputting the information he was given. "1969, that's an easy one! Funny, how some years are easy. Now, 1482, full of glitches. Now then, Canton Everett Delaware the third. That was his name, yeah? How many of those can there be? Well, three, I suppose." He watched as Rose stormed out of the room. River followed her. He turned to see Kiam sitting up on the pilot seat looking at a book with Jack. "Jack is everybody cross with me for some reason?"

"I'll find out," Jack said and left the room.

"What did daddy do?" He asked Kiam sitting down next to him. Kiam just smiled at him. He was tempted to enter the boy's mind and find out but instead he had another idea. He picked Kiam up and set him on his lap and moved Kiam's hands to his temples. "Close your eyes." He said softly and watched the little boy do so before he closed his own eyes.

"Show Daddy, what happened today." He says and he receives vague images of a beach. Something was coming out of the water and he saw himself heading to the water to greet it. Then a flashing green light and the image went black.

He opened his eyes and gently lowered Kiam's hands as the little boy opened his eyes. "Good job." He was extremely proud of Kiam but concerned with what the images meant. Rose was surprised he was alive and someone, he suspected the Master, had called them all there. He watched as the three of them entered the room again and stood around staring at him.

"Time isn't a straight line. It's all wibbly wobbly. There's loads of boring stuff like Sundays and Tuesdays and Thursday afternoons. But now and then there are Saturdays." He says happily and stands up putting Kiam back down on the seat. "Big temporal tipping points when anything's possible. The Tardis can't resist them, like a moth to a flame. She loves a party, so I give her 1969 and NASA, because that's space in the sixties, and Canton Everett Delaware the third, and this is where she's pointing." He turns the screen to where they can see it.

"Washington D.C., April the eighth, 1969. So why haven't we landed?" Rose asks him.

"Because that's not where we're going." He tells them and turns around to lean against the console.

"Oh. Where are we going?" Jack wonders.

"Home. Well, you are. Back to Ianto and saving the world. And Doctor Song, back to prison?" He looks at her and she nods. "Thought so. As for us, Rose has a wedding to plan and I need to do some repairs."

He looks at there faces staring at him confused. "What? A mysterious summons. You think I'm just going to go?" He runs his hands through his hair and then looks at each of them in turn. "Who sent those messages? I know you know. I can see it in your faces." He rubs his forehead. "Don't play games with me. Don't ever, ever think you're capable of that."

"You're going to have to trust us this time." River tells him. He steps away from the console and moves closer to her.

"Trust you? Sure. But, first of all, Doctor Song, just one thing. Who are you?" She just stares at him. "You're someone from my future. Getting that. But who? Okay. Why are you in prison? Who did you kill, hmm? Trust you? Seriously."

"Trust me." Rose speaks up.

"I do trust you." He walks over to her and looks her in the eye.

"You have to do this, and you can't ask why." She says finally.

"Are you being threatened?" He asks letting his anger rise. "Is someone making you say that?"

"No."

"You're lying." He tells her quickly.

"I'm not lying." He looks deep into her eyes and then kisses her softly on the lips. Pulling back " My life in your hands, Rose Tyler."

"Thank you." River tells Rose.

"So! Canton Everett Delaware the third. Who's he?" He asks loudly heading back to the screen. The three of them gather behind him.

"Ex FBI. Got kicked out." River says. "Six weeks after he left the Bureau, the President contacted him for a private meeting."

"Yeah, 1969. Who's President?" He asks.

"Richard Milhous Nixon. Vietnam, Watergate. There's some good stuff, too." Jack answers him.

"Not enough." He mumbles.

"Hippie!" River exclaims.

"Archaeologist."

"Okay, since I don't know what I'm getting into this time, for once I'm being discreet." He runs around the Tardis flipping levers. "I'm putting the engines on silent." He flips a switch and everything go silent. "Putting the outer shield on invisible. I haven't done this in a while. Big drain on the power."

"You can turn the Tardis invisible?" Jack asks surprised. He flips the wrong lever and the place lights up.

"Very nearly." River remarks and moves the lever near it.

"Did you touch something?" He asks looking at her.

"Just admiring your skills, sweetie." She smiles at him.

"Okay. Now I can't check the scanner. It doesn't work when we're cloaked." He starts to head to the door and notices they are all following him. "You lot, wait a moment. We're in the middle of the most powerful city in the most powerful country on Earth. Let's take it slow." He turns and steps out of the Tardis and closes the door behind him.

He sees two men sitting at a desk. One is obviously Richard Nixon and the other he assumes is Canton. They are both concentrating on the recording that is playing.

"Hello? Who is this? This is President Nixon. Who's calling? Is this you again?"

"Mister President?' A little girl says.

"A child." Canton sounds surprised.

"This is the President, yes."

"I'm scared, Mister President. I'm scared of the spaceman." She tells him.

"A little girl?" Canton asks.

"Boy" Nixon replies.

"How can you be sure?" And Nixon gestures back at the recording.

"What spaceman? Where are you phoning from? Where are you right now? Who are you?" He reaches into his pockets and silently pulls out a notebook writing down the answer.

"Jefferson Adams Hamilton." The little girl answers.

"Jefferson, listen to me." The Nixon on the recordings says but the recording cuts off.

"Surely this is something the Bureau could handle, sir."

"These calls happen wherever I am. How do I know the Bureau isn't involved? I can't trust anyone." Nixon looks up and sees him standing there. Realizing he has been caught he backs up into the Tardis.

"Hello, this is the Oval Office? I was looking for the oblong room. I'll just be off, then, shall I?" Canton jumps him and wrestles him to the ground as the secret service run in.

"Lockdown! Lockdown!" One of them cries out.

"Stop that!"

"River, Jack, have you got my scanner working yet?" He calls out.

"Get the President out of here. Sir, you have to go with them, now."

"River, make her blue again!" He calls out and to his relief the Tardis reappears in front of them.

"What the hell is that?"

He stands up and moves off to the side away from their grasp as they gawk at the Tardis.

"Mister President, that child just told you everything you need to know, but you weren't listening. Never mind, though, because I'll take the case." He raises his hands as he realizes they all have their guns trained on him still. "Fellows, the guns, really? I just walked into the highest security office in the United States and parked a big blue box on the rug. Do you think you can just shoot me?"

"They're Americans!" River calls out as they all rush out of the phone box. Kiam tries to follow but Jack blocks him in.

"Who the hell are you?" Nixon asks them.

"Sir, you need to stay back." Canton warns him.

"But who are they and what is that box?"

"It's a police box. I'm your new undercover agent on loan from Scotland Yard. Code name the Doctor. These are my top operatives, the Wolf, the Immortal, Mrs Robinson and the Baby."

"Who are you?"

"Nah, boring question. Who's phoning you? That's interesting." He moves away from them slowly. "Because Canton is right. That was definitely a girl's voice, which means there's only one place in America she can be phoning from."

"Where?" Canton asks him.

"Do not engage with the intruder, Mister Delaware." One of the Secret service tells him.

"You heard everything I heard. It's simple enough. Give me five minutes, I'll explain. On the other hand, lay a finger on me or my friends, and you'll never, ever know."

"How did you get it in here? I mean, you didn't carry it in."

"I'm Clever" He tugs on his left ear and smiles.

"Love it. Five minutes?"

"Five." He replies.

"Mister President, that man is a clear and present danger to..." The agent begins but Canton cuts him off.

"Mister President, that man walked in here with a big blue box and three of his friends and a child, and that's the man he walked past. One of them's worth listening to. I say we give him five minutes. See if he delivers."

"Thanks, Canton."

"If he doesn't, I'll shoot him myself." Canton says looking towards him

"Fair enough. I'm going to need a SWAT team, ready to mobilize and Street level maps covering all of Florida."

"Get him his maps."

-DW-

He has the maps spread out all over the office and is looking for a specific point on the map.

"Why Florida?" Canton asks curiously.

"There's where NASA is. She mentioned a spaceman. NASA's where the spacemen live. Also, there's another lead I'm following." As he turns back to the maps the phone rings.

"The kid?" Canton asks.

"Should I answer it?"

He finally pinpoints the location he was looking for. "Here! The only place in the United States that call could be coming from. See?" He points to the map and Canton comes over and looks. "Obvious, when you think about it."

"You, sir, are a genius."

"It's a hobby." He says proudly and Rose rolls her eyes.

"Mister President, answer the phone." Canton tells him.

"Hello. This is President Nixon."

"It's here! The spaceman's here! It's going to get me! It's going to eat me!" The little girl cries out.

"There's no time for a SWAT team. Let's go." He heads back to the Tardis and the rest follow him. "Mister President, tell her help's on the way. Canton, on no account follow me into this box and close the door behind you." They all enter and he rushes to the console.

"What the hell are you doing?" He makes sure they are all on board and watches Canton close the doors and then flicks the lever to send the Tardis on its way.

"Jefferson isn't a girl's name. It's not her name either." He turns around. "Jefferson, Adams, Hamilton. Jack?"

"Surnames of three of America's founding fathers." Jack answers him. "Lovely fellows. Two of them fancied me."

"You see, the President asked the child two questions. Where are you and who are you? She was answering where." He tells them. "Now, where would you find three big, historical names in a row like that?"

"Where?" Rose asks him.

"Here. Come on." He lands the Tardis and grabs Rose's hand and heads to the door.

"It's er" Canton says as they pass him.

"Are you taking care of this?" He asks Jack.

"Why not?"
