"Oi you're going the wrong way!" Donna exclaimed crossly when the drive missed the turn. She leant across pulling the Santa hood off the driver revealing the robot underneath.

"Bloody hell", Alyssa swore seeing what the driver was.

"Help us!" Donna cried hitting the window trying to get the other cars attention. Alyssa yanks the handle on her door but it was locked.

"Wish I had a sonic screwdriver", Alyssa muttered while Donna was still yelling for people to help.

"What are you doing?" Donna asked as the other red head start kicking at the window.

"What does it look like I'm doing? I'm. Trying. To. Get. Us. Out", with each word Alyssa kicked the window. She was about to snatch Donna heels and try them when the TARDIS zooming alongside with its doors wide open showing the Doctor piloting her with a piece of string.

"Open the door!"

"What the hell do you want us to open the door for?" Donna asked.

"Duh so we can escape", Alyssa replied in a matter of fact way. "Door's locked!" she shouted to the Doctor. He used his sonic on the door so that the women could push the window down.

"You two are going to have to jump"

"I'm not bleedin' jumping I'm supposed to be getting married!" Donna said shrilly. The robot put his foot down. With some pretty nifty manoeuvring on the Doctor's part he managed to catch up with the Taxi again. He sonics the robot disabling it.

"You two need to jump", the Doctor said again.

"I'm not jumping on the motorway", Donna insisted.

"Oh for crying out loud", Alyssa said before giving Donna a shove out of the Taxi. Thankfully the Doctor caught her as she collided with him.

"Ali come on", he said holding his hand out to her. Alyssa prepared herself to jump but she froze.

"I-I can't", she stammered.

"Ali you have to. I'll catch you"

"You promise?"

"I promise"

Alyssa took a breath before leaping out of the taxi. She like Donna knocked the Time Lord over.

"Ali you can open your eyes now", he said as she clung onto him eyes closed. "You ok?" the Doctor asked when she eventually opened her eyes.

"Yeah", she replied getting up to allow the Doctor to stand. Alyssa shut the TARDIS doors and the Doctor pilots the ship up into the air.

"How are you holding up?" Alyssa asked sitting next to Donna on the roof that the Doctor had parked the TARDIS.

"Well I missed my wedding", Donna said gloomily.

"Sorry about that. Couldn't you book another date?"

"We could"

"You've still got the honeymoon", the Doctor added sitting down next to them.

"It's just a holiday now", Donna said still sad. To the surprise of Alyssa and Donna the Doctor pulled out what looked like a wedding ring from his pocket. "Do you have to rub it in?"

"Those creatures can trace you. This is a bio-damper should keep you hidden", the doctor explained slipping the ring onto her finger "With this ring, I thee bio-damp".

"For better or worse", Donna joked.

Alyssa looked at the ring on Donna's finger and she got this feeling that the ring wasn't going to be able to shield Donna. "So the robot Santa's, what are they for?" she asked.

"Your basic robo-scavanger. The Father Christmas stuff is just a disguise. They're trying hard to blend in. I met them last Christmas"

"Why, what happened then?" Donna asked.

"Great big spaceship? Hovering over London?"

"I remember that. All those people standing on the rooftops, my mother along with them. I don't think I've ever been so scared when I couldn't stop her from walking to the edge", Alyssa said starting to fiddle with the charm bracelet around her wrist. She knew it didn't go with the dress but the jewellery held so many memories that she couldn't bear to take it off.

"I spent Christmas Day just over there, the Powell Estate. With this family. My friend, she had this family. Well, they were…" the Doctor trailed off lost in thought. Alyssa put her hand over his and gave him a small smile when he looked at her. Donna watched the two of them and wondered if there was something between the pair.

The Doctor got up to go over to Donna so he could scan her with his 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"

"This friend of yours, just before she left did she punch you in the face?" Donna asked feeling insulted.

"I don't know if she did but if the Doctor says another thing to insult you I will be punching him", Alyssa said to Donna. She was also feeling a little insulted despite the Doctor not talking directly to her. "Where do you work Donna?"

"HC Clements. That's where I met Lance. I was temping", Donna replied. She began to explain how exactly met her fiancé.

"When was this?" the Doctor asked.

"Six months ago"

"Bit quick to get married", the Doctor commented.

"Not really if he's the right person for you", Alyssa said.

"What about you two?"

"What about us?"

"Are you two together?" Donna asked.

"No he's just a friend. I have a boyfriend, Ben", Alyssa replied quickly.

"Anyway you may have missed your wedding but you still have the reception", the Doctor said changing the subject. He helped both women to their feet and they make their way to the reception on foot this time.

The reception hall falls silent when the trio entered the room. "You had the reception without me?" Donna asked shocked that they would do that.

"Well it was all paid for, why not?" a blonde replied looking at Donna with obvious dislike.

"Why not? I'll tell you why not. You don't have a reception when one of the people it is for is missing. Doesn't matter if you've paid for it", Alyssa said deciding that she didn't like the blonde.

"Who the hell are you?"

"I'm Alyssa, Barbie. Donna's friend", Alyssa said putting an arm around the bride.

"Well what the hell happened to you Donna? How did you do it? I mean, what's the trick because I'd love to know", Sylvia asked. Then suddenly the whole room starts talking at Donna. Alyssa wanted to yell at them to get them to lay off of the poor bride. They had no idea what she'd just been through. She didn't even get the chance to because Donna started to cry. Lance pushed Alyssa out of the way so he could hug her. Donna winked at both Alyssa and the Doctor through her fake crying. The other red head was impressed how she could 'cry' on cue like that. Alyssa leans against the bar with the Doctor looking on at the party going on in front of them.

"You know I did get dressed up. Fancy a dance Doctor?" Alyssa asked as the music became more upbeat.

"Sure"

They went to the dance floor to join the other guests. While pair danced, the Doctor noticed another couple nearby. When the man dipped the blonde woman and then brought her back up reminded him of something similar that happened when Cassandra left Rose's body during their trip to New Earth. Without realising it, he'd stopped dancing with Alyssa. She looked over and realised that the couple must be bringing back memories for the Doctor. He'd promised to help her move forward on the day of the funeral and she wanted to do the same for him. Alyssa noticed the camera man in the corner who was recording everything. "Doctor lets go talk to the camera guy. He might have caught what happened to Donna during the wedding", she said to him. The Doctor nodded and they headed over to him.

"Hi. I was curious about Donna's disappearing act. Did you catch it on tape?" Alyssa asked him.

"You bet I did", he replied. Moments later the trio was watching Donna's disappearance.

"What the?" Alyssa said when Donna vanished in a golden glow.

"It can't be", the Doctor said. He got the cameraman to play it again. "But that looks like Huon Particles!" he exclaimed.

"What's that?" both Alyssa and the cameraman asked in unison.

"That's impossible, that's ancient! Huon energy doesn't exist anymore, not for billions of years! So old that…" the Doctor looked at the gold ring on Donna's finger.

"The bio-damper doesn't work", Alyssa finished. She was mentally kicking herself that she didn't say anything about the feeling she'd had back on the roof. The Doctor rushed over to the window while Alyssa approached Donna.

"They've found you", she said taking her to one side.

"But the Doctor said I was safe"

"The biodamper doesn't work. We have to get everyone out now", the Doctor said when he joined them.

"Let's go out the back", Alyssa suggested which the Doctor agreed. However, when he opened the back door they saw two robot Santa's standing there. The trio back away and head to the window where more robot Santa's were outside. The Doctor glanced at the Christmas trees when both robots raised the remotes in their hands.

"Christmas trees…"

"What about them?" Donna asked.

"They kill", he replied with a serious look on his face. The three quickly try and get people away from the evil evergreens.

"Stay away from that tree!" Alyssa ordered to the remaining people who were too close to the tree.

"That woman is an idiot! What's a Christmas tree gonna do?" Sylvia asked. She got her answer when the baubles float off the tree and hover above everyone. The wedding guests were excited at first until the baubles started dive bombing them and exploding. One bauble landed near Alyssa's feet. Suddenly she saw tackled to the side as it exploded, it was the Doctor. He quickly pulled her to one of the tables.

"Stay under here", he instructed before charging over to the DJ's stand. Alyssa ducked under the table just as he said to. She heard him say something through a microphone before a high pitched screeching noise rang through the air. Alyssa clapped her hands over her ears to try and block out the noise. Alyssa crawled out from under the table when the noise stopped. She saw the robot Santa's in pieces. She and Donna walked up to the Doctor who was examining the Robo Santa's parts. "You ok?" he asked them both but he was looking at Alyssa.

"I'm ok"

"Me too. You're a Doctor people have been hurt", Donna said. The Doctor just ignored her and carried on working.

"Who's been hurt Donna?" Alyssa asked her face full of concern.

"Uh"

"Donna you said people have been hurt. I do have some basic first aid training"

"Right. This way"

Donna led her over to some guests that had injuries. Thankfully none of them were too serious. As she was cleaning up a cut on a man's arm, a little girl wandered up. "Hello"

"Hi", she said shyly.

"Have you been hurt?" Alyssa asked and the girl nodded. "Where?"

"I scraped my knee when hiding under the table", she explained.

"Alright let's have a look at it", Alyssa said. The girl sat on the chair while the woman inspected it. "I'm going to clean it now. It might hurt a little bit but I promise I'll be gentle"

Alyssa gently dabbed her knee with a wet napkin "I'm Alyssa. Whats your name?" she asked as she cleaned the scrape.

"Connie"

"That's a lovely name"

"Thank you"

The Doctor paused in his work and watched Alyssa interact with the little girl. He smiled when the woman kissed the girl's knee before the girl got up from the chair and hugged her. Alyssa then stood up and wandered over to him with a smile on her face. "You're pretty good with kids", he commented.

"I used to babysit for my neighbour in college. They were much younger than Connie though. Anyway what have you found out from that?" she asked geusturing to the robot head he had in his hands.

"Nothing yet"

"Really? I'm surprised you can't hear the beeping coming from that", she said. The Doctor held the head up to his ear and sure enough he heard the beeping too. He grinned at her

"There's still a signal!" he said jumping up. Alyssa followed the Time Lord out of the building. "There's someone behind this, directing the robo-force", he said scanning the head.

"Who?" Alyssa asked as Donna joined them outside.

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

"If we find the controller, we'll find that out. Oh!" the Doctor raised his sonic into the air and looked up. "It's up there. Something in the sky" That made both women look up.
