He never noticed, until he met Rose, how often he had come across the term "Bad Wolf". It was like when he came in contact with the actual source of the phrase, it magnified itself. Like a word search, when you're looking for a specific letter or combination of letters, they began to stand out.
Rose really outdid herself when she scattered the phrase through all of Time and Space. Not only did she scatter it throughout their travels together, but she managed to spread it throughout his lifetimes. He was still seeing it now and then, even in his thirteenth body. Although the sad pang his hearts had dulled by the centuries that had passed between then and now, but still undeniably there.
A small sigh shook him out of his revere, and he glanced down at the sleeping child before him. He quietly closed the book and stood next to her bed. He smiled at the tiny tot, asleep well before the big bad wolf could blow down the house of sticks.
"Donna Kayley, you've made Grandpa happy," he whispered, kissing the blonde child's head goodnight.
From the doorway, Jenny smiled at her father and daughter.
