Jack sat beside the Doctor when he took the sonic, wrapping his arm around him and bringing him close. Watching the Doctor examine the sonic and listening to him as he tried to figure out how something that seemed impossible, possible and what could have happened to the Fob Watch. "If the Master is behind this and has plans for Arwen, we will need to be careful. I don't think she is safe here anymore." He declared, though he didn't expect her to be a Time Lord. "So she is a Time Lord? Or is it Time Lady. Either way, couldn't you find out with some DNA testing or something? See if she is your sister?" Jack asked curiously.
