Donna looked at her watch. Half past three. She had missed it. Behind her, the Doctor was coughing and sputtering as he sprayed an extinguisher inside the TARDIS doors, smoke billowing from inside.

"I'm sorry." Rose said, coming up behind her, placing a hand on her shoulder. Donna just nodded.

"The funny thing is," The Doctor said, walking over to join them. "For a spaceship, she doesn't really doesn't do that much…flying. We'd better give her a couple of hours. You all right?" He asked Donna. She just shrugged.

"Doesn't matter." She said quietly.

"Did we miss it?" He asked as they walked to the edge of the high rise building that they had landed on, looking out over the city.

"Yeah." Donna told him sarcastically.

"Well, you can book another date…" Rose tried to console her.

"Course we can." Donna said sadly.

"Still got the honey moon…"The Doctor tried to cheer her up.

"It's just a holiday now." Donna said.

"Yeah…" The Doctor said. "Sorry." He apologized.

"It's not your fault."Donna told him with a half smile.

"Oh! That's a change." The Doctor said, smiling, the wind ruffling his hair.

"Wish we had a time machine." Donna said. "Then we could go back and get it right. The Doctor and Rose glanced at each other, and he shook his head a tiny bit. Rose nodded to show that she understood. They weren't going to tell her.

"…Yeah. Yeah." The Doctor said. "But…even if I did. I couldn't go back on someone's personal timeline. Apparently." He couldn't help but think of the Time War, and how tempting it always was to go back and change the way things turned out, to save his people. Donna glanced at him oddly, then went to go sit of on the edge of the roof. Rose grabbed his hand and squeezed it comfortingly. She knew what he was thinking of. He smiled at her slightly, then they went to go sit next to her. The Doctor removed his coat, and draped it around Donna's shoulders. It was windy up here, and she was only in her wedding dress and starting to shiver. Donna clutched it around her gratefully as The Doctor sat next to her, reaching over to grab Rose's hand.

"God, you're skinny." Donna said. "This wouldn't fit a rat." She told him. The Doctor just smiled at her.

"Oh, and you'd better put this on." He told her as he pulled out a ring from one of his pockets that looked suspiciously to a wedding ring.

"Oh, do you have to rub it in?" Donna asked, somewhat indignantly.

"Those creatures can trace you." He told her. "This is a bio-damper. Should keep you hidden." The Doctor slipped the ring on her finger. "With this ring, I thee bio-damp." He said with a smile, popping the 'p'.

"For better or for worse." Donna said with a small smile, which The Doctor returned. "So, come on then." Donna said. "Robot Santas. What are they for?"

"Ah, your basic robo-scavenger." He said dismissively.

"The Father Christmas stuff is just a disguise." Rose added. "They're trying to blend in." Donna looked over at her. "We met them last Christmas." She explained.

"Why? What happened then?" Donna asked, slightly confused. The Doctor and Rose looked at each other.

"Great big spaceship?" The Doctor said.

"Hovering over London?" Rose added. "You didn't notice?"

"I had a bit of a hangover." Donna said with a dismissive shrug. With another glance at each other, The Doctor and Rose decided not to pursue this.

"I spent Christmas Day just over there." He said, scanning the city below them. Rose looked and smiled.

"The Powell Estates." She said. "My family lives … " Rose hesitated as she remembered that she couldn't just pop back in to see Jackie anymore. The Doctor squeezed her hand comfortingly. "Well, my mum used to live there." She said quietly. "Still…gone now."

"What happened?" Donna asked. Sensing that Rose didn't want to talk about it, The Doctor interrupted.

"Question is, what do the camouflaged robot mercenaries want with you?" He asked. "And how did you get inside the TARDIS? I don't know…" he trailed off, contemplating her. Donna just rolled her eyes. "What's your job?" he asked as he pulled the sonic screwdriver out of his coat pocket.

"I'm a secretary." She said looking at him as he began scanning her with the sonic screwdriver.

"It's weird. I mean, you're not special, you're not powerful, you're not connected, you're not clever, you're not important…"

"Is he always like this?" Donna asked Rose, slightly insulted. Rose rolled her eyes.

"You're being rude again." She told The Doctor.

"Rude and not ginger." He said with a grin, as he continued to scan Donna, who whacked the screwdriver aside.

"Stop bleeping me!" She cried.

"What kind of secretary?" Rose asked.

"I'm at H.C. Clements. It's where I met Lance." Donna said with a small smile. "I was temping. I mean, it was all a bit posh really. I'd spent the last two years at a double glazing firm. Well, I thought, I'm never gonna fit in her. And then he made me a coffee. I mean, that just doesn't happen. Nobody gets the secretaries a coffee. And Lance, he's the head of HR! He don't need to bother with me! But he was nice. He was funny." Donna's voice softened. "And it turns out he thought everyone else was really snotty too. So that's how it started, me and him. One cup of coffee. That was it."

"When was this?" Rose asked.

"Six months ago." Donna said with a smile.

"Bit quick, to get noticed…" The Doctor pointed out.

"Well…he insisted." Donna said. "And he nagged…and he nagged me… And he just wore me down and then finally, I just gave in."

"What does H.C. Clements do?" The Doctor asked.

"Oh, security systems, you know…" Donna told him. "Entry codes, ID cards… that sort of thing. If you ask me. It's a posh name of locksmiths.

"Keys…" The Doctor said musingly, still trying to figure out what was going on.

"Anyway, enough of my CV. Come on, it's time to face the consequences. Oh, this is gonna be so shaming." She said, already dreading what was coming. "You can do the explaining Martian-boy." She told The Doctor with a smile.

"Yeah, I'm not from Mars." He told her. Donna nodded as he got to his feet and helped Rose up. Then he reached down and offered her a hand up.

"Oh, I had this great big reception all planned." She said as she stood. "Everyone's gonna be heartbroken."
