Sophia Weaver was Captain Daniel Weaver's youngest daughter. Her father and mother separated a year before the invasion and her mother got engaged again. When the invasion came, she was captured by the Skitters and harnessed. Her father found her and brought her back to their house where he attempted to remove the harness. However, this resulted in her death. Weaver has been mourning his daughter's death ever since - and seems to suffer from insomnia as a result. He keeps one of her drawings with him at all times.
