"I've found a small device that can display broadcasts. Like a televisiion or radio... As soon as I turned it on, I was greeted by a message of morse code and wierd reception. The message was simple. She was out there. She was alone. Could anyone hear her? I had to find out who she was.

Try as I have, I've come to the conclusion that there is no way to send broadcasts, only recieve. I await something new. She is alone. She is desperate. Just...like me. I feel like maybe she's here too. Or maybe she was?

Laura Sharpe. Her name is Laura Sharpe. If only we could talk, Laura Sharpe."
