Caitlyn watched the Doctor having heard about his 'Oncoming Storm' look and tone of voice. That question made her itch to speak again but she knew this was their show down but if any of them continued to make remarks to which she had a remark to she wouldn't be able to hold her tongue much longer. It was a relief she hadn't said anything by now actually. She made no secret that she was an outspoken individual. Rose was proud of her cousin and how she seemed to be holding herself from making a stupid remark, but knew that there would come a time when her 'speak before you think' tendency would come out. It was only a manner of when. She kept watching the Doctor and the Master.
