Don't worry, the Doctor thought back. I won't go anywhere.

He had a few days left before he'd have to sleep, especially after that deep sleep back in the TARDIS. But he wouldn't move, he decided. He was far too comfortable. Far too happy like this. And happy wasn't something he often had in this lifetime. It was worth it to stay.

He wouldn't leave, he promised himself. Wouldn't leave Jack alone, not after all of the times before. He'd build him another homing beacon, he'd----he'd do something to prove he wouldn't go. Not again.
