Chapter 2: Giant Droid Death Match
The Doctor and Rose watched in astonishment as the girl, who had just saved their lives, began fighting the robot. She was punching holes in it and taking every opportunity she could to yank out a few wires. Rose could hardly believe what she was seeing; that girl couldn't have been any older than 16, and there she was, having a death match with a 7-foot tall robot… and winning. In a few seconds it was on the ground.
The girl turned to The Doctor and Rose. "You okay?" she asked.
"I was gonna ask you the same," said Rose, "What were you doing back there? You could've gotten yourself killed!"
"And yet you're still alive," said The Doctor, "Who are you?"
"My name's Yumi Ishiyama, and to answer your question," --she pointed to Rose-- "I take martial arts classes."
"And they teach you how to do that in your classes?" The Doctor asked, pointing to the robot which was now smoking.
"I did it, okay?" Yumi snapped, "Why are you interrogating me? You'd be dead if it weren't for me! A little 'thank you' would be nice."
"Yes," said The Doctor, "Very well. Thank you." He held out his hand, expecting her to shake it. Yumi simply gave him a long, cold stare and walked away.
There was a moment of silence, and then Rose spoke up. "We gonna follow her?"
"Yup."
With that, The Doctor and Rose followed Yumi into the factory.
