Sam stifles a groan at the idea of another climb. "No problem," she replies. "There was-..." She breaks off as something tickles at the back of her mind. "Actually, hang on..." She reaches to turn her lamp back off, and there, up ahead, she sees it. "I can see some light up ahead," she says. "There must be a grate." Bert can hear Sam's breathing speed up just a shade as she picks up her pace, crawling quickly along to the spot ahead. Then there's a sharp intake of breath - almost a shriek, though not quite.

"Fuck!"

A few moments of fast, almost panicked breathing.

"I'm okay, I'm okay, I'm just a bloody idiot, nearly went straight down a shaft in the dark."
