Master shanking!
While part of Nine wished Eleven hadn't been so obvious, he also was thinking that the Master was probably expecting a sneak attack. So perhaps this way would throw him off. Nine made sure his sonic screwdriver was well secured. Part of him was tempted to give it to maybe Rose or River, as no doubt if they were caught the Master would remove it. But it was his favorite weapon. If it could be called a weapon.
I wish I had kept Jack's sonic blaster he thought to himself. Glancing up, he met Eleven's eyes for a moment. Then he followed his older self's gaze to the others. River. Oh so beautiful and dangerous River. Nine was definitely a fan of her and would be lying if he said he wasn't attracted to her. She clearly had a wild side and he found that very sexy. As his eyes moved on he noted that Rory chap in the Roman armor. Nine didn't know much about him other than he was River's father.
And then there was Rose. His beautiful Rose who had saved him after the Time War. Whether she knew it or not. Nine knew he only had met her because of Sexy. Sexy had known, however she knew things, that Rose had been the one he needed. And Nine didn't want her here. Things could get ugly and if Romana was with the Master...
He pushed the thought away of what would happen and glanced at Eleven as he spoke. "Let's just get this done," he said in reply.
