Well, that was one way to meet someone new! Especially the Doctor's (apparent) daughter, which was still a very strange concept... and how the girl had explained it went completely over Rose's head. Complicated or not, like Donna, Rose hadn't been expecting to see the girl, let alone while running from, well, whatever those things were? Heartless? Were these what Maleficent had been referring to?

"Hi there, nice to meet you!" Rose said quickly, steps ahead of the other pair now. She remembered where they were now, and knew the way back to the TARDIS; a relief, really. "Those things won't be able to get into the TARDIS," she added, then caught sight of another Heartless leaping their way. "Run!" And she was on the move again.
