It was always so easy to want to stay free. The Doctor used to think, in his youth, that he was flawed if he wasn't free. But now, here, it...it wasn't so bad, not really. Jack understood adventure, he understood the need to travel. The Doctor could feel Jack's longing to reassure him cross the connection.

There was nothing to be afraid of.

So why was the Doctor still utterly terrified? Probably because of how very, very easy it would be to shatter this. To lose this between them. And, really, if anyone could shatter this, it would be the Doctor----

He felt Jack's mind shift, and he lifted his head to watch Jack lower himself down his body. The term "sexy" seemed like an understatement when Jack had that look in his eye. And the Doctor didn't often use the term "sexy" in general thought.

You do know in some galaxies this is the equivalent of torture, right?
