Kevin Arkwright

Kevin Arkwright was a twelve year old boy on a school trip to Xirrinda to research for an exam. He and his friend Matty George volunteered to help the Eleventh Doctor to control the boiler pressure of the monorail to allow them and all the passengers to escape to Ortagon City. His liquorish sweets helped Rory to distract the creatures as they blew up the train. (NSA: Rain of Terror)
