The stinky sock Tub had mocked earlier went tumbling down the stairs until it was swallowed by darkness. A few rogue marbles followed suit and we did not hear them land. Jack bounded downward. He was almost out of view before realizing we hadn’t moved. “Let’s go,” he snapped. Tub and I stared at each other, then at the bed being held over our heads by ARRRGH!!! as if it weighed no more than a sheet. She nodded us on, her horns ripping through my posters and helpfully rearranging my models. I descended with baby steps. Soon my eyes adjusted to the dim orange glow radiating from underground electrical grids. But this remained a staircase without a railing, and I moved with a caution that frustrated Jack. He sighed and took steps by threes and fours. It made me feel lousy—this thirteen-year-old kid was making me look bad—but what else was I going to do? I inhaled the briny funk of troll, tried to ignore the slither and thump of their weird appendages, and focused on maintaining my slow and steady pace.
