Venus feels a tugging around her ankle, feels her foot going numb, then a trickle of blood, cool and wet over fuzzy pins-and-needles flesh. Some of the thread's thin enough that it tightened around her to cut off circulation and sliced her until it snapped. It doesn't even hurt yet. "Careful for the threads, they'll cut right through you!"

There's a sound of metal slamming on metal behind them, and figuring there's no way that's good, Venus picks up her pace even more, wiggling through the entrance as it tightens. She reaches back through for Guy. "Move! Come on!"

They're almost clear.
