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. (thetvdb.com)
