"Well it went so great the last time I tried to tell you, didn't it?" Jack scoffed a little. Really it'd gone terribly.

He shook his head and thought about it. What did he want? What exactly did he want? It'd probably be much easier to explain it if he could possibly understand it himself.

"Nothing," he said finally, looking up at the roof of the cave. "Nothing really. I mean- you're my best friend, Doctor, you mean the world to me, you really do. And you know, I'd just really been starting to enjoy whatever was changing. I guess we'd never been alone together for so long before to realise it might. And you know, that sort of stuff?" he shrugged his shoulders back, "How we were getting? I just think that'd be nice. More of that, without worrying about what it means and having to question it. Maybe that's just too much me and not enough you, but I don't know, I don't think it is, and you know I've definitely got a dose of what you had."

He frowned slightly. He was being rather frank, wasn't he? Maybe the effects were just slower on Jack. A delay on his less advanced metabolism.

"Oh and that's a lie," he added, "because you already give so much. And it's a fine line between can't and won't."
