"So, are you two, like, together?" Amy asked as her, Donna, and the Doctor walked through the hall in the 'Mysterious building'.

"No." They both said in unison.

"We're not even the same species! And have you seen how skinny he is?" Donna continued at the same time the Doctor was saying, "We're just friends. Why does everyone always think we're together?"

"Whoa! Okay, I was just asking." Amy giggled. This Doctor was different from her Doctor. But she thought her Doctor probably would have gotten defencive, too.

The Doctor stopped suddenly and Donna nearly walked into him, "Oi!"

Amy noticed them stop and turned back, waiting for them to move.

"Did you hear that?" The Doctor asked. He swore he just heard something. Like it was inside his mind. When the others shook their heads looking confused he knew he was right. He waited but didn't hear anything else. "Come on." He said and they continued walking. While they walked the Doctor went over in his mind what it could have been. It might have been a species like the Ood calling out. But as far as he knew there were no other species on Lily 9 besides the humans. But it wouldn't be the first time he discovered another species. The thought of discovering something new got him excited.

"Amy, did your Doctor mention anything about the planet?" The Doctor asked.

Amy thought about this for a second. She hadn't really been listening.

"Like what?" Amy asked after a few seconds of thought.

"Anything about the inhabitants?"

HA! Now, that part she heard. Maybe not all of it but enough.

"The Doctor said they were humans. I wasn't listening that well." She added sheepishly.

The Doctor nodded and looked thoughtful.

"What is it?" Donna asked noticing the look on the Doctor's face. His eyebrows were knitted together in concentration.

"I heard something before. Someone calling out." Was his answer. Donna knew if he heard someone asking for help he'd be running. There was more to it than what he said.

"I didn't hear anything." Amy said sounding confused.

"No, you won't be able to hear it, humans can't," He explained. Donna thought it might be like the Ood. The Doctor said he heard singing but she couldn't hear anything, not until the Doctor did something to her mind.

"You hear it in your head, yeah?" Donna asked.

Before the Doctor could confirm what Donna said, he heard it again:

Help me!

He stopped again. He closed his eyes to focus. The voice was of a little girl. He felt her, and others in his mind. Over a hundred he decided. Men, women, children, a whole race of people living on this planet and no one knew. They were hiding from the humans, he decided. But why?

He located the girl who was calling to him. He could feel she was scared.

I'll be right there, just hold on. He sent her through his mind.

Amy and Donna watched as the Doctor stood there with his eyes closed. What was he doing? Donna thought he might be listening to whatever was 'calling to him' earlier. Her theory was confirmed when his eyes few open and he bolted forward and ran down the hall.

Amy and Donna ran, struggling to keep up with the time lord.

Ah. Sorry, I ended a chapter with running again didn't I? xD I think this chapter was good :) so hopefully that means im getting better at writing ;D review and tell me what you think ;)
