Robin felt a surge of relief as the Doctor closed the doors of the TARDIS. those Vikings had been terrifying and disgusting, and she doubted that she wanted to have any sort of interaction with them at all. She resumed her former seat on the rail, watching the Doctor flip switches and do other strange things, smiling at the almost routine feel of it.<br/><br/>The smile vanished as Robin and the Doctor were thrown to the ground violently. For a moment, she could only lie there stunned, feeling an ache already beginning in her elbow. Getting up more slowly than the Soctor, she felt confused and bewildered. Could something actually stop the TARDIS?<br/><br/>After the Doctor had spoken, Robin was silent for a moment. He looked intrigued, an she couldn't help feeling kind of the same way. Automatically, her ham reached up and toyed with the chain of her locket. A strange beeping noise faintly prodded at the back of her mind. Beep... Beep... Beep...<br/><br/>"Doctor," she said, tugging on the little heart on the chain. "Can they do that? Can they stop the TARDIS? What is that beeping noise? And why do you look so excited?"
