Anwei's eyes grew huge in the darkness, not that anyone could see. Suffocation was a constant threat in space, but they weren't in space, right? They were under gravity, under the ground. All they had to do was get out.

She tried to move her hands down, but she couldn't. She squirmed, but there wasn't any room for her to move back, not with Billy in here with her. But by rolling back and forth a little, she felt the long cylinder of her flashlight-laser.

Unfortunately she had no way of reaching it. But maybe -

"Billy - under me. A flashlight-laser, at my right hip. Can you reach it?"

Maybe they could at least burn a ventilation hole - or signal for help.
