Letting just his lips slip out of the stone beneath the single bench/cot in the cell, Sandy let her know that the handcuff was slowly working it's way out of the wall so she could catch it to keep from making noise.

There'd be time enough for making noise soon.

Then he told her that she was getting out of there, that people had come for her, and that if she saw a man made of stone, to trust him. If she didn't find a man made of stone, she should head right (which was the direction of Scott's cell).

Then he had other things to do. Like poke Scott awake from underneath where hopefully the guards would have no idea he was there.
