The toxic, corrosive substance produced by the lizards did work, just like Lane had said it would. After Team Leader Hannah Jones led a small group of Espers out of the cave to collect lizard monsters' carcasses - Damien couldn't, because he was too attached to Lane… Literally - they were able to use the substance to slowly dissolve the webbings. It caused extensive burns, just as Damien had feared…
But Etan's and Jasper's skin was already raw and partially eroded in places where the spider threads were stuck, so it didn't make that much of a difference. Even Lane's skin was in a terrible state… Although that had been achieved mainly through his own effort. Because the threads' properties didn't affect him nearly as strongly as the others for a reason that he couldn't explain, he had made sure to squirm and struggle enough to achieve a satisfactory result through friction, rubbing his body against the threads until it was bleeding.
