Red vs. Blue

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.

As Sarge makes preparations to call Simmons to get his take on Epsilon Church's visions, Doc recovers and wakes up at the base with Simmons, who explains the details of Washington and the Meta to him. After hearing that Doc had experience with Omega previously, Washington tells him to examine the Meta, who is suffering from armor problems. Back in the desert, Sarge uses Epsilon Church to boost the Warthog's radio and contacts Simmons, but receives a forced message from him under Washington's supervision. Fortunately, using nothing more than his knowledge of his teammates and Simmons' communication, Sarge instantly deduces the situation at Valhalla. As he and Grif set off to rescue them, an intrigued Epsilon Church follows.

Doc informs Washington that the Meta is physically healthy, although having serious problems with his armor. In the desert, Tucker searches for the Reds and Epsilon Church, and guesses they must have taken off. Caboose warns Tucker not to say anything about Epsilon Church missing, as the aliens would become hostile if they knew he was gone. Meanwhile, Sarge arrives in Valhalla to help out Simmons and Doc, and attempts to lure Washington to the center of the canyon. Washington moves to out to intercept him after telling The Meta to kill the prisoners if Sarge caused him any problems. With Washington gone and the Meta distracted, Simmons and Doc plan to short circuit the Meta's suit using an overpowered charge on Doc's medical scanner. Washington confronts and disarms Sarge and demands to know where Epsilon is, but at Sarge's signal, Grif bursts through the canyon wall in the Warthog, landing on Washington and pinning him under the car. With the Warthog still moving at a high speed, Wash climbs from under the Warthog and onto the front, and attempts to shoot Grif. Grif slams on the brakes and Wash is thrown into the opposite cliff alongside explosive barrels as Sarge reclaims his shotgun. He fires at the barrels to ignite them, attempting (but failing) a one-liner, and Washington is engulfed in the resulting explosion. As the episode ends, the Meta sees the explosion and readies to execute Doc just as Doc charges his "scanner."

Epsilon-Church finds the gap in the Valhalla wall caused by the warthog, and continues to follow the reds. At the base, Doc fires his medical scanner at the last second, blasting the Meta against the wall. The blast overloads the Meta's temporal distortion unit, causing him to be slowed down rather than him slowing down time. However, he is still able to land a single punch that caused Doc to fly back and get trapped in the wall. As Sarge and Grif arrive, Simmons declines to help Doc as the Meta begins to resume normal speed, and rejoins his team. Returning to normal temporal relativity, the Meta pursues the fleeing red team, destroying their warthog. As the reds prepare to make a last stand against the Meta, Epsilon-Church arrives, serving as a decoy to lead the Meta back towards blue base while the reds escape. Red team runs back through the hole made by the warthog, arriving in Isolation. As they catch up, Epsilon-Church appears and reveals that he lost the Meta, but is still being followed. He is about to reveal who he came here to look for, the reds begin insulting him, so that he may activate his laser and seal the gap, preventing the Meta from pursuing. It doesn't work at first, but when the Meta and the now-recovered Agent Washington appear beyond the hole, the sight of Wash enrages Epsilon-Church, who inadvertently fires his energy weapon and seals the gap, trapping Wash and the Meta on the other side. This frustrates Epsilon-Church, but before he says why, he loses power and falls. Back in Valhalla, the Meta is angry that they got away, but Washington mentions that they still have a source of information: Doc, who is still trapped in the wall at blue base.

The Reds return to the desert to find Caboose being threatened by the aliens as a result of Epsilon-Church going missing. Tucker informs the aliens that the Reds took Epsilon in order to draw them off of his own back. Meanwhile, as Simmons and Grif try to wake up Epsilon-Church, Sarge is leading the aliens, and thanks to a series of warnings, Grif is able to punt Epsilon away just after he comes to. The aliens arrive with Sarge to see no signs of Epsilon-Church. The Reds flee in the midst of the distraction, and Caboose abandons Tucker, leaving him to face the aliens alone. The Reds and Caboose locate Epsilon, who landed in the mine field after he was punted away. Grif tells Simmons, who is unaware of the mine field, to go get him and Simmons hastily retreats when he accidentally activates a mine.

Washington and The Meta plan to interrogate Doc after they pull him out of the wall with an anchor but it does not go as they had planned, meanwhile The Reds and Caboose get visited by a memory of Delta who tells them that Epsilon is not in control but searching for memories as, Epsilons encounter with Washington has jogged many of its memories, and that Epsilon has not "Coped" with the memories well and fears Epsilon will pursue "certain" memories in particular and states that Delta himself and the other memories of the Alpha fragments will not be able to hide much longer as he states Epsilon will be aware of their presence eventually.The Delta fragment warns Caboose that "Memory may be the key, but everything that is locked is not meant to be unlocked" and leaves before he is discovered. Epsilon-Church awakens again and says he remembered something important and that it may be able to help him and asks Caboose to accompany him to a facility before night fall.
