Watchers? The Doctor shook her head. "No. Who're they??"
She beamed when he complimented her and cocked her head to the side to think about it. "Rose is um...my friend. Best friend, actually. Hadn't seen her in years, though, til this place. She got stuck in another dimension for a bit. She's blond. Very British. You'd get along, I think."
The Doctor nodded empathetically as Peter explained who he was, especially about the feeling older than your years bit. She could relate. "So like the other Peter? Um, the one that runs Pancho's." The Doctor knew him well enough. "That's amazing that there're two of you! Brilliant, actually." She smiled widely and looked out into the darkness.
