grandfather and the box with the timed lock is in the closet in their house. By now the timer has finished counting down and the lock has clicked open. When searching the closet, Lina's grandmother finds the box but tosses it aside, not realizing its importance. The opened box is found by Lina's baby sister, Poppy. When Lina comes home, she finds Poppy with torn pieces of paper in her hands and mouth; Poppy has all but destroyed the instructions.
