"You would never do that," Robin replied, sticking her tongue out at the Doctor. "I'm too much fun to be around." The teasing did stop, however, as the elevator opened and revealed a big, dark room. For some reason, Robin felt a sinister sort of presence as soon as she stepped into the chamber. A shiver ran down her spine (though the room was pleasantly warm) as they walked.<br/><br/>Approaching the giant machine, she felt herself grow more and more anxious, and the beeping increased in intensity again. Her light grip on the Doctor's arm turned tight, and she was almost squeezing it by the time he started scanning it with the sonic screwdriver. And then she heard it. The soft, nearly silent whisper echoing through her head.<br/><br/><em>Come to me. We will rid the universe of life. Come, Daleks, come to me.</em>Another shiver racked her entire body as she listened.<br/><br/>"I hear it, Doctor," she said softly, her eyes wide with fright. "Why is it calling the Daleks? Why would it want to get rid of all life in the universe? I thought this tree was supposed to<em>bring</em>life... Not take it away."
