My theory regarding the Plurb and breeding

!Building a "transmitter the size of Africa" would require a lot of labor and the Plurbs can selectively breed some excellent workers. Some defensive line dudes from the NFL for heavy labor, people that have small hands for detail work, and the like. I also suspect a very utilitarian and brutal program to get rid of undesirables. Think Nazi "eugenics" without the violence. Hive resources are better used

!I also suspect that the Hive has already impregnated at least one of Carol's eggs into a host and are going to use it to emotionally manipulate her. Plurb'd up son/daughter toddler telling mommy Sturka "JOIN US MOMMY WE LOVE YOU".
