Martha followed Donna around the shops. She felt a little out of place, although she did purchase a few knickknacks for family and friends. Wondering what the Doctor had sensed, she ran right into the redhead.

"What do you suppose that is?" she asked, pointing toward the glowing chandelier in the center of the corridor.

"It's a light," Martha said, unsure of what she was supposed to be seeing.

"I know it's a light. It wasn't glowing like that a minute ago."

Martha took another look. The center support was glowing just as brightly as the bulbs. "I don't know what's causing that," she said with a frown. "You said it just started doing that?"

"Yeah." The two women stared as they watched a very familiar figure tear down the corridor. "What's he on about?"

"I don't know," Martha said, "But if he's running, we'd better join him."

It took a moment to get out of the store, but once they did, they took off running the way the Doctor had. They stumbled to a halt as a blinding light flashed. "What the bloody hell was that?" Donna asked, rubbing her eyes.

Martha didn't bother to answer, because as her eyes cleared, she noticed something that she never wanted to see. The TARDIS vanished in front of her.

"That alien went and stranded us here!" the redhead screeched as she noticed the missing ship.

Shaking her head, Martha tried not to give in to the crushing fear. "I don't think so," she said slowly. "There was no noise, no wind, no fading out. It just disappeared."

"You're right," Donna said as she calmed down. "So, how are we going to get it back?"

The woman shrugged. "There has to be something around here to tell us what's going on," she said. "The Doctor took off that way, so I suggest we do the same."

Donna grabbed her arm as she started to move. "Do you see it?"

"See what?"

"The people."

Martha took a long look around. "They're shopping?" she asked, not quite sure of Donna's point.

"Yeah, they're shopping, but they're doing the exact same thing they were doing when we first got here."

Frowning slightly, she tried to see what Donna saw. "What exactly do you mean?"

"See the woman in the red? She was at that same exact table."

"She could just be a slow eater," Martha said.

"Except that she got up and left just afterwards. She threw her garbage in the same bin that the Doctor was poking around in."

They watched in amazement as the woman did exactly what Donna had noticed. "How'd you know that?" Martha asked breathlessly.

"I liked her outfit." Shrugging, she grinned. "So I like clothes. Sue me."

"All right. Let's go see if we can find out what spooked the Doctor," Martha said. "We'll watch out for other instances of repeats, okay?"

"Sounds good."

They walked through the corridor, fighting serious déjà vu as they went. "How come we're not repeating like they are?" Donna asked finally.

"I don't know. Maybe because we came in after whatever this is happened." Martha scanned the crowds nervously. "At least no one's scared or anything. That's all we'd really need was a panic."

Both women gave the glowing chandelier as much distance as they could as they passed it. Neither of them spoke as the light flashed again. Prepared for it this time, they tried not to react to people vanished and appeared around them.

"Clueless lot, aren't they?" Donna muttered.

Martha didn't reply, but she agreed with the assessment. She kept her eyes open for something suspicious, but nothing stood out. "I swear. There has to be something here that made the Doctor take off like that," she said. "But I can't see anything…"

"What?" Donna asked as Martha stopped. "What is it?"

"Shh."

Irritated to be shushed, the redhead opened her mouth to protest when she heard the familiar buzzing. "Isn't that…"

"The sonic screwdriver!" Martha said, grinning broadly. "That's the Doctor!"

They looked around for the alien, but there was no sign of him. Listening, they followed the sound toward a plain door tucked away between two shops. Frowning, Donna stopped. "Where is he?" she complained when they couldn't see him.

"I don't know," Martha said. Peering toward the door, she noticed the blue glow shining on the metal door. "Over here," she whispered, tugging Donna's arm. "I saw it."

"Then why are we whispering?" Donna asked.

"Because I don't think the Doctor had it. I think someone stole it."

To her credit, Donna seemed suitably affronted that someone would take something that was so personal to her friend. They slipped toward the dark figure holding it.

Martha felt her breath freeze in her throat when she saw the man holding the screwdriver. Donna didn't notice her hesitation and charged the man. "Hold on there. What do you think you're doing with the Doctor's things?"

"What? I am the Doctor!"
