In every single scenario he'd run through in his head, not one had considered Danny would simply believe him. If's Hex had been hearing the tale for the first time he would never believe it. It was mad, wasn't it? And there was no way to prove it.

But there was Danny, watching him across the distance, and his only concern was if Hex was safe. It was hard to let go of his anxiety, but bit by bit it began to fade when he realized Danny wasn't going to immediately call for an ambulance.

"I...I don't think so. Not in any sort of immediate way. I understand there are always risks when people travel with the Doctor. Sort of paints a target on me back, yeah? Something about chronotrons and being affected by the realities of time travel. But as far as I know, no one's out to get me."

And even as he said it, he didn't sound certain. What about this Jack fellow? If he'd shaken Danny so much maybe Hex had a reason to be afraid of him, too.
