"Well, let's hope it doesn't snatch you when you're on your own, then," Martha replies as she adjusts her pace to match him. She has no idea how the mansion appears to him, but she wouldn't be surprised if it's enough to slow him down. "Though I'm sure you'd manage. And it couldn't hold you there forever, after all."

At least, she hopes not. That would be truly horrifying -- stuck in some made-up scene from a telly program for the rest of time.

Martha pauses as they reach the stairs, turning back toward him. "We may as well walk up together, yeah?" They're both on the eighth floor, so it makes sense.
