AN: This story takes place during the SG-1 Episode '1969' and for the Doctor's personal timeline, the part in 1969 happens just after the third season episode 'Blink' while the 1999 sequence occurs after 'Voyage of the Damned'

August 1969

Colonel Jack O'Neill wrinkled his nose at Carter's comment. He wasn't looking forward to living out the rest of his life from 1969 onward. "Where there's a will there's an 'or'. We're going to get out of this and back to where we belong."

The van they were in gave a sudden jerk. O'Neill frowned at his other team mates just as Carter asked, "What was that?"

The rear doors swung open. One of the lieutenants transferring SG-1 climbed in.

O'Neill raised an eyebrow at him. "Flat tire?"

"I was the one who arranged it," he said. He studied the four faces in the van as they looked at him in surprise. "Before I can even think of doing what's asked in the note, I need to know who you are and who gave it to you."

"Oh my god," Carter said suddenly, reading the lieutenant's nametag. "My name is Samantha Carter and... you gave me the note, sir." At the confused looks sent her way by Daniel, Hammond and O'Neill, she went on to explain, "Sir, before we left, General Hammond gave me a note and told me to keep it in my vest pocket until we got to the other side."

Hammond put in, "It's addressed to me, in my handwriting."

Generally curious, O'Neill asked, "What does it say?"

"Help them. And seeing as helping you will undoubtedly lead to court-martial, I'd like to know why I would do that."

Before Carter or the others from SG-1 could answer, a voice from outside the van replied. "Because, George, I'm guessing I asked you to." The lieutenant swung around and saw a young man stood a few meters away. SG-1 peered over Hammond's shoulder to see a man in a brown pinstriped suit and a tan overcoat staring at them. His left hand hung loosely at his side while his right was in his trouser pocket. "You have a zatnicatel?" the Doctor asked as he approached the van.

Hammond looked down at the weapon in his hand. "Do you mean this?"

He allowed the Doctor to take the weapon off him. "I haven't seen one of these in years." Looking up, the Doctor spotted SG-1 cuffed in the back of the van. "Oh hello. No don't tell me. You're SG-1, lead by Colonel Jack O'Neill with Captain Samantha Carter, Doctor Daniel Jackson and Teal'c." The Doctor levelled his gaze at Teal'c before returning his attention to Hammond. "Their gear is following, right?"

"Yeah. What are you going to do with that?" Hammond's eyes darted to the zatnicatel in the Doctor's hand.

"Oh, this? Nothing." The Doctor slid the gun along the floor of the van and pulled out his screwdriver.

"Excuse me, but who are you?"

The Doctor looked up into O'Neill's questioning gaze. "I'm the Doctor."

"No other name with that?" Daniel asked.

"Nope. Just the Doctor." His gaze flickered to Hammond. "Do you still have the note?" Hammond nodded and handed it over to the Time Lord. The Doctor unfolded it and read 'George, help them. The skinny idiot.' "Trust him to write this." The Doctor looked up at the young Lieutenant Hammond. "Not this you but older you. Is the security footage in with their gear?" At Hammond's nod, the Doctor smiled. "Good. This saves you from court-martial." Lifting his free hand, the Doctor put pressure on Hammond's neck to knock him out. "I'll apologise the next time I see you." He released SG-1 from their bounds. "Let's go."

"What did you do?"

"I knocked him out." The Doctor frowned as O'Neill picked up the zatnicatel and levelled it at him. "Do you really have to point that thing at me? What is it with humans and guns?"

SG-1 got out of the van and stood, two on either side of the Doctor. The truck with their gear ground to a halt as the driver realised the prisoners had escaped. The Doctor turned slowly to face the truck and the men climbing from it. Their weapons were drawn. O'Neill reacted first, firing two shots of the zatnicatel, one at each man. The Doctor turned on him and opened his mouth as if to reprimand him.

Instead, he said, "All you'll need is a GDO from your gear. It'll be in the back." He moved off to the side of the road and into the forest. Teal'c's gaze followed him as Daniel, Carter and O'Neill moved to the back of the truck.

Once they rejoined the Doctor off the road and had moved a fair distance from the military men, Daniel broke the silence. "Before, when Jack had the zat pointed at you, you talked about humans and guns as if you weren't, well—" he trailed off, and the Doctor looked at him with amusement.

"As if I wasn't human? What about you? You're friends with someone who's reliant on a Goa'uld larva for his immune system. And if memory serves me, you lot travel through a stargate on a daily basis. Well, that is if you're in the correct time period. Well, not exactly every day. Well, once or twice a week. Well, once a fortnight. Anyway, the point is, you lot defend against hostiles from other planets and that's brilliant. If not a little stupid."

Carter frowned. "What does that mean?"

"I stumped the scientist. Big clue Samantha Carter, I know what the Stargate is and what you apes call it. And on top of that, I got stuck in 1969 just like you."

"What time period are you from?"

"Time's relative." For a brief moment, his face was clouded with sadness and SG-1 was startled at the agelessness of the Doctor's eyes. It was replaced by a cheeky grin. "Enough of that. Do you want a lift home?" The five of them had made it to the next interstate and the Doctor was making his way to an odd blue box.

"We got sent back thirty years by the stargate. What makes you think you could get us back to the correct time?" Daniel asked.

"I told you, time's relative to me." The Doctor stepped inside the box. "I must warn you not to touch anything once you're inside."

"Isn't that 'Police Box' a little small?" O'Neill asked. "I mean, do you expect five of us to fit in there?"

The Doctor appeared at the doorway with a smirk on his face before disappearing back inside. Carter was the first to approach the door to the TARDIS and to enter. Her mouth opened and shut a few times before she asked, "This is a temporal dimension, isn't it?"

"Yes it is. To be precise, this is a Time and Relative Dimension in Space, otherwise known as the TARDIS. My TARDIS. Now, if you'd like to step on board?"

"It's a police box. These things are obsolete. Won't anyone notice it?" O'Neill asked as he stepped into the TARDIS behind Daniel and Carter. Teal'c followed him.

"Nope. And they're still common in England. Well, in 1969. Although there aren't so many actual police boxes around in 1969. 1963 you could find a police box on every street corner." The doctor looked up from the control panel at O'Neill just as the colonel was about to pick up a jacket of Rose's. "Oi. Don't touch anything."

"This thing's amazing," Carter said.

Daniel swivelled his head around. "It's definitely not Earth technology. At least, nothing we've discovered yet."

The Doctor shot a warning look at the archaeologist. "And you're not going to either. Someone give me a date from where you're from."

"March 5th, 1999," Teal'c said.

"Everybody hold on. Next stop, Anteaus's place. Well, their world. Everyone, hold on. This could get a little bumpy."
