Yumi wormed her way through the crowd with ease, throwing glances behind her regularly, to make sure that she was still within eyeshot of the Doctor. The crowd was getting thicker now and Yumi had to be careful not to lose sight of the Doctor. Somehow she had to get to the front of the crowd without losing the Doctor.

Good luck, Yumi!

It was surprisingly easier than she had thought. Yumi squeezed her way to the front of the crowd and looked over what was going on. There were a lot of soldiers surrounding where whatever it was had come down and they were gradually pushing the barriers backwards. Yumi looked up at the Doctor as he came up behind her.

"OK," she said. "Now what?" The Doctor looked thoughtful.

"Hm," he said, casting his eyes around the soldiers. "UNIT."
"Huh?" asked Yumi. "What's UNIT?"

"It means, Yumi, that I can get in and find out what that thing is."

"What about me?"
"Stay where you are for the time being. I'll tell you when you can come in." Immediately he ducked the barrier and went under. Yumi sighed.

"Great," she said sarcastically. "And I thought I was going to be able to do something interesting."

"Yumi?" Yumi started and looked behind her.

"Yeah?" she asked and then saw who it was.

"Li?" she asked, looking at the boy behind her. "What's going on?"

"No idea," he replied, but it turns out that whatever's going on it's important. They have soldiers down here. That's gotta be important, right?" Yumi nodded.

"Guess so. Anyway, do you know where the others are?"

"The guys are with me. We came to have a look whilst on the way to meet the rest of you."

"So you've no idea where the rest of the girls are?"

"No, sorry."

"Never mind," said Yumi. "I'm waiting for someone."

"Who?"

"Yumi. Come and look at this." Yumi smiled and pointed towards the Doctor.

"That," she said and ducked under the barrier. A few UNIT soldiers began to approach her but the Doctor's voice called out.

"No, she's with me. It's all right." The soldiers stopped, but Li leaned over the barrier.

"Why, who is he?" he asked.

"That's the Doctor."

"What do you mean by that?" he called after her as she walked off. "What do you mean 'the Doctor'? Doctor who?"

Yumi felt exceedingly important as she weaved her way over to the Doctor and levelled with him. When she came to look at what it was that he was calling her to look at, it was quite frankly a disappointment. It just looked like a lump of metal.

"What's that?" she asked. "A lump of metal?"

"Probably," he responded, taking a funny contraption out of his pocket.

"What's that?"

"Sonic screwdriver," he answered in an almost automatic way as he scanned the lump of metal. Yumi sighed.

"Oh, because that makes sense." She leant in closer. "Sooooooo, what does it tell you."

"It tells me," said the Doctor, without looking up, "that this object here fell through time and space tracks."

"Is that bad?"

"It depends where it came from," the Doctor replied. "Just a minute." He pressed the screwdriver against the metal.

"What are you doing?"

"I'm taking a sample of the metal's structure," said the Doctor, putting the screwdriver back into his pocket. "I'll need the TARDIS to analyse it completely."

"What's the TARDIS?"

"You are very fond of questions, aren't you, Yumi?"

"Sorry," muttered Yumi. "That's just how I am? So, can I come? Please." The Doctor smiled.

"Come on then." Yumi grinned and whirled back around in the direction they came.

"Back this way, right."

"Yes."

Li watched Yumi and the Doctor leave. Seriously, what was she up too? Gathering the Kurou and Ryouta, he began to follow them. It wasn't as easy as he thought. They seemed to have vanished by the time he passed the subway station. Li cursed. Either he'd taken a wrong turning or been too slow. Either way he couldn't get hold of Yumi right now. Li looked around at his friends as if about to ask what to do next, but was interrupted by a smash of metal on stone. All three froze and followed the sound with their eyes. They gaped when they saw what had made the noise. Standing on the edge of the street where two men, but they didn't look like men. They were made entirely of some kind of metal. Li swallowed and bit his lip as the two metal men began to march down the road towards them.

"Uh oh."
