Jack could feel his heart beating, but more than that, he could feel the Doctor's hearts beating. Not just hear them, like a distant thud if he were to put his hand over the Doctor's chest or his fingers to his wrist. But he could feel them like the beat of his own heart. Three hearts, beating together, racing together.

And the Doctor's hearts really were racing.

He looked to him again, and he understood that, that feeling he felt from him, that almost fear. But that was good to feel that. It was all just as important as the rest. To feel the excitement, the love, the sheer amount of it all? Well that was frightening. And it was wonderful.

But this wasn't going anywhere; a feeling Jack made quite clear. It wasn't something that he was going to allow now, from either of them.

But then those thoughts were swiftly distracted. Jack had been called sexy of course, many a time. But never had hearing the word sent a wave up his spine as it did when hearing it from him, even in his mind.

He grinned then, looking at him, and moved that extra distance to replace his hand with his mouth.

Well I am skilled in all methods of interrogation, of course.
