"I taped the whole thing." He said. "They've all had a look. They said 'Sell it to "You've Been Framed"' I said, 'More like the news." Here we are…" He played the tape. As The Doctor and Rose watched, the camera zoomed in on Donna's face as she walked down the aisle. Suddenly she stopped and screamed as she seemingly disintegrated into golden particles.

"Can't be!" The Doctor said in disbelief. "Play it again?"

"Clever mind! Good trick, I'll give her that. I was clapping." The cameraman said as he rewound the tape. The Doctor watched the tape again, his brow furrowed incredulously.

"But that looks like…Huon particles!" He said in disbelief.

"What's that then?" Rose asked.

"That's impossible! That's…ancient!" The Doctor explained. "Huon particles don't exist anymore, not for billions of years! So old that…" He trailed off as he realized something, and his eyes were drawn to the biodamper he had placed on Donna earlier. "…It can't be hidden by a biodamper!" His eyes widened as he realized this, and he and Rose looked at each other in horror, than he broke away and sprinted to a nearby window. Sure enough, standing there were the Santas, making their way slowly to the reception hall. The Doctor rushed over to Donna, Rose right behind him.

"Donna! Donna, they've found you!" The Doctor cried as they ran up to her on the dance floor.

"But you said I was safe." She protested.

"The biodamper doesn't work." Rose told her.

"We've got to get everyone one out." The Doctor said and Donna looked around her.

"Oh my god…it's all my family…" She breathed as she realized.

"Out the back door!" The Doctor told her, and the three of them ran out of the hall and out the back door, only to be confronted by two more Santas. Doing an about-face, they slammed the door shut behind them, and Rose leaned against it.

"Maybe not." She said, then the three of them ran back inside. The Doctor darted to another window, and pulled back the curtain only to see two more Santas standing below them.

"We're trapped." He said, staring out the window at the Santas, his breath fogging up the glass. But what caught The Doctor's attention was the remote control the Santas were holding. And as they watched, the Santas slowly raised it. The Doctor stood there for a moment in confusion. Then he realized. Whipping around, he stared at the Christmas tree in the middle of the room.

"Christmas trees…" He muttered in growing horror.

"What about them?" Dona asked.

"They kill." Rose told her grimly.

"Get away from the tree!" The Doctor cried as they raced back into the crowd of the reception.

"Don't touch the tree!" Rose shouted.

"Get away from the Christmas tree!" Donna yelled as they tried to usher people away but all they were getting was strange looks.

"Everyone get away from the tree!" The Doctor ordered as Donna ushered a group of little girls away from the tree.

"Oi!" She cried, trying to get people's attention. "Lance, tell them!" she appealed to her fiancée for help.

"Stay away from the tree!" Rose shouted again as she helped The Doctor usher people away. She recalled all too vividly what had happened last Christmas. A Christmas tree, controlled by those Santas, had almost killer her, her mum, Mickey, and the newly regenerated Doctor. "Can't you stop them?" She asked The Doctor.

"Not enough time." He told her. "Just every, please! Stay away from the tree!" he pled with the crowd.

"Oh, for god's sake." Sylvia said striding forward and crossing her arms. "The man's an idiot! Why?" She demanded to know. "What's a Christmas tree…" She started to say, then trailed off with an "Oh!" as she stared in amazement. The Doctor, Rose and Donna all whirled around and stared with the rest of the crowd as the ornaments floated off the tree and began to hover above peoples' heads in a strange sort of dance. The Doctor watched them suspiciously, whereas the others were laughing and smiling, thinking nothing of the seemingly harmless show. That was, until the ornaments started dive-bombing and exploding. Instantly there was chaos as people started screaming and running for cover. Donna pulled Lance underneath a table to hide with her and The Doctor grabbed Rose's hand and together they dived behind the DJ's table. The Doctor poked his head up when the explosions ceased and found himself confronted by all the Santas, lined up opposite them.

"Oi! Santa!" He cried, rising to his feet. "Word of advice! If you're attacking a man with a sonic screwdriver," Here he leaned down and spoke into the microphone so that his words echoed across the hall, "Don't let him near the sound system!" He told them, the pointed his sonic at the amplifier and turned it on. Immediately, there was a horrible, high-pitched screeching sound and everyone covered their ears. But the Santa robots started to vibrate violently. The Doctor kept the sonic on until the robots fell to pieces. When they did, The Doctor finally turned off the sonic and put it back in his pocket, then rushed over to examine the Santas. Everyone in the hall began to get up off the floor. Donna ran over to two of the kids.

"Michael? Connie?" she asked, looking them over to make sure they weren't hurt. The Doctor picked up the control the Santas had been using to control the ornaments.

"Look at that." The Doctor said, showing to Rose as Donna came up behind them. "Remote control for the decorations." He explained, seeing Donna's confused look. "But there's a second control for the robots." He realized as he took apart a robot's head. "They're not scavengers anymore." He said, looking up at Rose. "I think someone's taken possession."

"But who?" Rose asked.

"Probably whoever took over H.C. Clements." The Doctor said, thinking.

"Never mind all that." Donna said. "You're a Doctor… people have been hurt."

"Nah… They wanted you alive. Look." He said, throwing her one of the decorations lying nearby. Donna caught it neatly, but was still unconvinced.

"All I'm saying – you could help." The Doctor rubbed the back off his neck with one hand.

"Gotta think of the bigger picture…." He told her, scanning the head with a sonic screwdriver. "There's still a signal!" The Doctor cried as he caught something, and took off running, Rose right behind him. Donna started to follow after them when her mother stopped her.

"Donna…" She said. "Who are they? Who are those people?" She asked, sounding scared. Donna didn't have an answer. The truth was, she really didn't know. But she followed after them anyways, leaving Sylvia and Lance staring after her as she followed them outside. The Doctor was standing out in the middle of the yard scanning the helmet he had removed from the Santa with the sonic screwdriver.

"There's someone behind this." He said. "Directing the robo-force."

"But why is it me?" Donna asked him. "What have I done?"

"If we can find the controller," He told her, "We'll find that out. Oh!" He exclaimed as he raised his sonic screwdriver in the air as it caught the signal. "It's up there." He said. "Something in the sky."
