Jack tried to laugh, though it didn't completely work. "You don't have to lie to me, Doctor," he hissed out as he squeezed on his hand, "I see right through you. But you are amazing, you just need to start believing your own hype."

Part of Jack was the most scared because he was sure that as soon as he was fixed, the Doctor would go and Jack wouldn't go with him. He'd made it quite clear that there was no place for him any more, not with him.

Being alone was saddening at the best of times. The thought of that now was downright terrifying.

"Yes you are," Jack said, correcting him, "you've got to go back to the TARDIS. Little ship'll be missing you if you don't, and you know she'll only get angry." He couldn't help but still have that new found fondness for the TARDIS. It developed and grew as much as his feelings for the Doctor had in recent weeks.

"We had some good times though, didn't we, Doctor?" he went on. He wanted his goodbye. He really really wanted it. If things were going to end (and despite the Doctor saying he wasn't going anywhere, Jack couldn't quite absorb it), he wanted to have things end with a goodbye that he could at least remember.
