…Shane's breath caught. She looked at the mess around her—the pipe, the lighter, the scattered crystals. She could hide it all in thirty seconds. She could tell Sarah she was fine, that she'd been about to flush it. The lie was ready on her tongue. But the word 'help' still sat in her unsent message. She looked at it, and then at the door. Shane pulled herself up, her legs unsteady. She reached for the doorknob. Her hand closed around the cool metal, and she stood there, frozen, as Sarah knocked again. "Shane, I'm not leaving. I will stand here all night." The knob turned in her grip. One motion. That was all it would take.
