Rogue had been crafting a calm, polite response to Teyla's very practical question when Woolsey opened his big mouth. Her temper flared and she sat up straighter, her hands clenching into fists.

"I don't feed on people, Mr. Woolsey," she said, the words like steel. "There's no genetic need for me to ever use my power, and frankly I'd love to never have to use it again. I've got over two hundred fully formed psyches riding around in my head with me and I'd be one happy camper if I never had to add another one to the mix."

She leaned back in her chair and tried to return to a sense of calm, but it just wasn't happening. They would ask about the limits of her powers eventually, so she might as well get it all out in the open. "If the touch only lasts a few seconds, the other person is fine, just a little disoriented. If it's longer, they end up unconscious, even comatose. By thirty seconds... By then, a normal human would be dead."

Ronon spoke up from his post against the wall. "So you've killed people with it." It wasn't a question.

"Yes," she confirmed.
