Donut flees from the approaching Blues, but, still unable to brake, Tucker runs over Grif and the Warthog with Sheila. Tucker radios the Red Team to tell them to turn off their radios. Initially they refuse, so Lopez sings a love song about Sheila over the radio until they relent. Meanwhile, Church and Tex meet Caboose's mostly incorrect mental images of the Red Team. O'Malley suddenly kills Caboose's mental image of Church — thus making Caboose completely forget who Church is — and the real one and Tex subsequently give chase. Eventually trapping O'Malley, the two, hoping that Tucker had been successful, shoot him, chasing him out of Caboose's mind. Without any means of jumping to another armor, O'Malley signals "cockbites" in Morse code as he gradually fades. However, in a scene deleted from the DVD he detects one last radio transmission from Doc, who is attempting to contact Blue Command, and takes possession of him.

Medical Officer DuFresne (Doc) arrives at Valhalla after Simmons had requested a medic from Command. Doc is initially happy to meet Simmons again, but Simmons says that Donut needs his help. Doc notes that Donut is dead, and that nothing can be done for him. Simmons says he is sorry, and admits that he sent the request because "they" forced him to, needing someone with medical training. Doc turns around to see Washington and The Meta, who knocks him unconscious. In the desert, Epsilon Church is enjoying his new status, making up speeches while being worshiped as a deity by the aliens. While delivering a eulogy for C.T. and the human members of his team, Epsilon Church trails off when he sees a dark figure in the distance. He follows the figure; as it walks into a building, he finds himself at the Valhalla installation. When Tucker gets his attention, Epsilon Church again finds himself back in the desert. Realizing that Epsilon Church has just had another flash of memory, Tucker tells the Reds that this has been happening with increasing frequency. When Epsilon Church recalls seeing a waterfall, Grif and Caboose say that it sounds like the Valhalla bases.

At the Blue Base, Tucker becomes ill. Church and Caboose discuss Tucker's sickness, which apparently he caught when the Sacred Quest team stayed overnight in a swamp. Church suggests the sword's power source could be giving off radiation. Church and Caboose have a reasonably light and friendly discussion regarding the nature of the sword, as Tucker rolls in pain. This friendly discussion even extends to Church mentioning that he would love to "live in [Caboose's] world for about 10 minutes" just to have some fun. At the Red Base, Simmons persists in trying to enter the Red Base to relay vital information about the war to the Reds. However, he still meets resistance from Donut and Grif until he very quickly changes out of his mostly blue armor to his original maroon armor. Apparently Simmons learned this ability because of his extreme shyness, which has led him to never use the base's toilet for three years. Back at the Blue Base, Church and Caboose question Andy on what might be causing Tucker's sickness and suggest that he, being a machine (and thus not able to get sick) go into the base, find out what is wrong with Tucker and report back. Since Andy is a bomb, the only solution he can provide is to blow up the base with Tucker inside, killing all the germs and everything around the base in the process. Finally, out of frustration, he tells Church and Caboose that if they want a medical diagnosis, they need to find a doctor. With that, Caboose says to Church "Please don't do it." O'Malley and Lopez bicker over who should pick up the telephone that is ringing inside their secret lair, while Doc decries their bickering. It appears that all three have survived their encounter with the Alien and that O'Malley has continued in his pursuit of taking over the universe. It would seem from Lopez's attitude toward O'Malley, all those attempts have failed miserably and this has caused Lopez to become quite cynical and disrespectful toward O'Malley.
