"See you at dinner, Jack," Rose said, giving him a sweet smile. He nodded politely in return and turned on his heel before walking off, trying to hide the skip in his step.

Heads on stiff-collared necks turned to the unfamiliar screeching of a low metal siren. Appearing on the first class deck of the Titanic was a blue box, washing in and out of reality. Jack's head snapped around. He'd heard that sound before. Before now, he'd forgotten, but suddenly the memories came flooding back to him and he remembered. He remembered the day when the man who called himself a doctor but was unable to save a life and the girl with blonde hair, whose name escaped him came to town. His reminiscence was broken when a woman with flaming orange hair jumped flamboyantly out of the blue box. The Doctor followed behind, a worried look on his face. Oh he should be worried, Jack thought. When I get my hands on him he'll rue that day.

"Just remember," the Doctor called back into the box. "That this is a fixed point in time. No-" He was cut off as two young people in their late teens barged past him, almost knocking him over. "Changing the course of history," he finished quietly.

"Okay kids, see you tomorrow at half past three," the flame-haired woman told them. "Don't get into any mischief."

"We won't," replied the girl. She was peculiarly dressed in tight blue trousers and a grey jacket of some sort. Her hair was jet black, shoulder length and unruly, like it hadn't been brushed in days and, when she stepped into the sun, Jack could detect a hint of red at the ends of her hair. Jack didn't get time to inspect the boy before they left the landing sight, talking in excited whispers and arm in arm. Gentle mutterings could be heard from the first class passengers, and Jack saw some of them even shake their heads in despair. Obviously they thought nothing special of this occurrence of out-of-control youths, probably third class passengers, and continued to file off the deck in order to prepare for dinner.

Jack had time to waste as he didn't feel the need to get ready for dinner, besides, how would he get hold of an actual tuxedo? Thievery? He sighed as he realised that it was not the way forward. The Doctor and the woman were now perched upon one of the benches and the woman was talking excitedly to him. Jack, with his hands in his pockets, walked closer to them, curious as to what there was to be so excited about.

"I can't believe we're actually here, Doctor," she said. "The sun is setting, the breeze is light and it's pleasantly warm. Donna Noble on the Titanic! What could possibly go wrong?"

"Now," he warned as he caught her eye. "Don't speak of what will happen to anyone. Not anyone, Donna."

"Excuse me," Jack said, coming to stand in front of them. "What won't you speak of?"

Donna's mouth slowly dropped open. The Doctor nodded politely to him, a trace of recognition in his eyes.

"Is that..."

"Yes."

"No way!" she said in a rather obtuse way.

"Yes way," the Doctor grinned. Jack looked behind him to see who they were talking about. Maybe it was Captain Smith or Mr Ismay himself but he saw neither of them. In fact, there was no-one there at all as they'd all gone down to prepare for dinner. Jack turned back to the two strangers.

"You lookin' at me?" he asked.

Suddenly the Doctor stood up, took his hand firmly and started shaking it vigorously. "Jack Dawson! Pleasure to meet you. This is Donna and I'm-"

"The Doctor, I know," Jack said, letting go of the Doctor's hand. "Nice to meet you, Donna." He winked at her. "Nice hair, by the way. Very... carrotty." Donna raised her eyebrows. "No, I don't mean it offensively! It's... nice." She lowered her eyebrows and Jack took this as a sign that she was no longer offended. He took her hand delicately and brought it to his mouth, meaning to kiss it, before she snatched it away in disgust.

"Carrot!" she flared. "You call me a carrot and then you expect to get away with a kiss? I don't think so, mate."

"British! I like the accent," Jack replied, trying to make it up to her: he hated being on bad terms with people but everything he seemed to say was an insult.

"For the record, there is no such thing as a British accent," she said smugly.

"Anyway," Jack tried averting the conversation to something different. "How come you know who I am?"

"How come you know who I am?" the Doctor said, throwing his question straight back at him. Jack narrowed his eyes.

"December 8th 1907. I was fifteen years old. Exactly fifteen. For my birthday, my parents took me out on the lake. They told me it was the start of an era, and that we were never going back to shore. There was a mini bypass that eventually led us out into the ocean, where we could sail aimlessly without want for anything but each other. When we had a better boat, we'd go to Europe and travel the world. That was the dream, anyway. Didn't exactly get that far, did we, Doctor?"

"Jack..." the Doctor trailed off.

"Doctor? What did you do?" questioned Donna. She gestured for Jack to sit down next to her and he perched on the arm rail, swinging his feet onto the wooden bench.

"It's more like what he didn't do, Donna," Jack said, his voice colder that she'd ever heard it in the film. He breathed deeply, the story obviously bringing back difficult memories. "We were picnicking in a dock just outside Minnesota when this loud siren noise sounded. Your box, Doctor. Now, my parents were old-fashioned folk and they promptly fell into the water which was, due to the time of year, far below freezing. The boat was overturned and I fell in too and saw them sinking to the bottom. I cried for help and the Doctor swam towards me and we managed to bring my parents to shore between us. But it was too late. You're supposed to be a doctor but you couldn't even make them live."

"Look, Jack-"

"No."

There was silence. The Doctor wanted to apologise, wanted to say sorry, but he could tell when someone needed their space.

"I trusted you and you gave me false hope," Jack whispered, two tears racing their way down his face.

"I'm sorry," the Doctor said. "I'm so so sorry."

Wiping his tears away, Jack's signature grin returned. "Who was the blondie with you, Doctor? She seemed like a pretty good catch."

"Her name was Rose," he answered in a melancholy voice, his eyes suddenly drooping. Donna flinched; she'd heard that name before and did a tiny shake of the head in Jack's direction.

"Right. I get it. Big break up or something?"

"Something like that, yeah."

"Donna, you never told me how you know me," Jack said curiously.

"I don't know you," she answered, all of those months practising lying to her mum about calories paying off. "I just thought I did. You look like an actor from where I'm from, that's all."

"But you knew my name, Doctor" he persisted.

"Did I? Lucky guess," he grinned widely. Jack smiled back half-heartedly and raised his eyebrows.

"Jack? Jack!" a soft voice called from a doorway into the ship and out of it emerged Rose DeWitt Bukater.

"No way!" Donna said again, her bottom jaw dropping just enough for her dignity to remain intact.

"Yes way," the Doctor smiled.

"Will you stop doing that?" Jack hissed under his breath before striding confidently over to Rose. "Ma'am." He took her hand and kissed it, and when he brought his head up he could see a faint blush forming on her pale cheeks.

"What on earth are you wearing, Jack?" she said, glancing down at his shaggy overalls. "We'll have to borrow some of Cal's, I'm sure he won't mind. Well he will, but I'm sure he won't find out."

"Whatever you say, ma'am," Jack replied innocently. Rose grabbed his arm and gently tugged him inside.

"Jack and Rose," Donna sighed. "The greatest love story ever."

"Apparently," the Doctor replied. They sat there for a while, gazing at the golden medallion of a sun being marched south by murky grey clouds. "We've got to have dinner, Donna Noble. What do you suggest: 1st class or 3rd?"

"Judging by the film, let's go third," she grinned. She promptly stood up, linked arms with the Doctor and pulled him up too. They began strolling down the deck. "Do you even know where the third class dining room is?" she asked.

"No idea," he replied. They continued walking for a bit and then Donna suddenly jumped in the air and grabbed the Doctor by the shoulders, her eyes wide with glee.

"I can't believe we're on the Titanic!"
