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." (thetvdb.com)
