Red vs. Blue (2003) : 7x10

Shortly after Simmons asks Lopez for explosives, Donut comes back from investigating Blue Base for parts, mentioning off-hand that Caboose took Epsilon with him. Simmons becomes upset, as returning Epsilon to the authorities was part of the deal that got the teams their new bases, and attempts to radio Sarge to let him know. Unfortunately, he is unable to make contact as Sarge's radio isn't working. Back in the desert, the guide explains the treaty between humans and aliens and that another human team might cause an incident. He does permit Sarge, Grif and Caboose to scavenge for parts and supplies as long as they don't wander off. As Sarge notes that something "doesn't feel right", the guide tells Smith to return to getting into the temple while he takes care of the others, as the camera swings around to reveal the dead bodies of the real investigation team.
