Even after making more pieces that she helped cleanse like before, Becky still couldn't tell what the shape of the monster he was trying to build was!
She thought William would start assembling a monster after making enough pieces. Yet he kept working non-stop over producing more pieces, as if the monster he was going to make was a massive one!
At some point, William would make some form of an array around a single piece. She couldn't tell what was special about the pieces he used for this, except that all of them were big balls. He used the time to wait for new ores to melt to make these arrays, then left the balls inside and returned to make more pieces.
Time passed fast, and without feeling it, three more days passed. William was focusing totally on working here, without caring about anything happening in the outer world.
