"I will ask you one more time, Sarah," Kirk's voice spoke distaste for her alias. "state your race and identity. That's an-"

"Order?" She raised an eyebrow in a Spockish manner. "Last I checked, orders were only for members of your crew." Her voice softened. "Come on, captain. I was just getting to like you three. Can't you give me a bit of trust, and let me keep my secrets to myself?"

"Those who withhold their identity generally have a criminal background." Spock said.

"I do have a criminal past, and you know it. But that's not why I'm staying tightlipped."

"Then why?" asked McCoy, frustrated.

"If I told you why it would defeat the whole purpose."

"Spock," Kirk said grimly. "find out who she is?"

"And how exactly is he going to do that?" asked Sarah. "Even if I could be looked up, we don't exactly have any computers here."

They were in a fire lit cave, where they had taken refuge from the daleks. Suddenly Sarah realized what Kirk was referring to.

She sprang to her feet. "Oh no, I don't think so. Come on! That's an invasion of privacy, a breach of cognitive personal space!"

Heedless to her words Spock was approaching, eyes locked on hers. Her race was immune to Vulcan hypnotism, though. She made a run for it, but she wasn't faster than him. Before Sarah knew what had happened, she was pinned against the rock wall.

"Now, just a warning, though I know you won't listen," she said. His hand was already on the central katra points of her face. "I have strength in the psychic department. If you go in I will push you out-"

Everything swam out of focus. There was only her mind, her thoughts, her memories...

Oh, and him. She let him see her most recent recollections, made him think he was winning, made him let down his guard. Then she pushed hard. Pushed him out of her mind and into his.

Her sight returned. Spock fell backwards, pain almost registering on his face.

"Sorry." She reached out a hand to help him up. "I did warn you-"

"Don't touch him." McCoy shoved his way in front, and bent down by Spock. He took out a medical instrument, and started scanning with it. Kirk glared at Sarah.

"Don't look at me like it's my fault!" she said. Spock had recovered, and stood up. Sarah felt the new veil of distrust between her and them. "Look, if you want my help you'll have to accept a few things. I don't hide this information for selfish gain. I hide it to keep others safe."

"Life forms detected." a dalek said, just outside the cave mouth. "Preparing to exterminate!"

Sarah turned to her friends, and said her new favorite word. "Run!"
