Everything Old Is New Again (S02E01)

Three months after Tex's second assault on the Red Base, Medical Officer DuFresne, known as "Doc," arrives in Blood Gulch and reaches out to Blue Command for instructions. He meets with the Blue Team to examine Tex, who has already passed away. Church fills Doc in on the situation, mentioning that both he and Tex are buried near the Blue base. Caboose helpfully summarizes the first season, revealing that Church is a ghost inhabiting Lopez's robot, which has been painted blue. Additionally, Caboose has taken to threatening Tucker in a deep, ominous tone. With no injuries to treat, Doc, temporarily assigned to both sides due to resource shortages, plans to head over to the Red Team when they suddenly launch an attack.
