Mr. Greene was a fighter in the 7th Massachusetts Militia Regiment and Terry Clayton's Second in Command. He and his daughter Tessa were willingly complicit in Clayton's plan to collaborate with the Skitters and ensure their continued survival. He was ordered by Terry to kill John Pope, but was overpowered by him. However, Pope decided to spare him and left him tied up in the basement. He continued to help Clayton hunt down the escaped kids for the Skitters. After Clayton's defeat, they were forced out on their own by Captain Weaver. It is unknown what happened to him, but seeing as all the mass's except for the 2nd mass were wiped out it is most likely that he is dead.
