Robin listened to the Doctor's postulations with growing horror. It was true... Everything they'd done so far had seemed almost too good to be true... Strange little coincidences that they had taken for granted every time. As she thought about it, there was a strange feeling inside her, as though she had forgotten something very important. Frustration made her narrow her eyes. What was happening?<br/><br/>Then, the tall, blonde, brilliant alien pressed a small button on the bolo tie's hidden device. The words that came from it seemed to make no sense, but the Doctor whirled around all the same, giving Robin a command. When she followed his gaze, she let out a scream. Nearly all the aliens they had met so far had been terrifying, but nothing matched the fear that this one inspired in her. Memories came rushing back to her; when they had been standing in the room, speaking to Greme, Robin had turned around only to see one of these things standing behind her. It told her what to say to trigger the Doctor's memory. Thinking back on it, this terrifying white alien had been a hidden companion on all of their adventures. Now, Robin found herself shaking as she looked into its mouthless face.<br/><br/>She walked toward the Doctor and pressed close to him. How was this possible? Could an alien really erase itself from memories like that?<br/><br/>"Doctor," she said, her voice soft. "What is that? And why do I only remember it when I look at it?"
