4x11 - Red vs. Blue

Sarge and Donut enter the Blue Base to rescue Grif without encountering any perimeter defense, such as Sheila. Inside the base, Grif is still playing with the gravity lift that Simmons originally mistook for a hole. As Grif runs to and fro on it, both Simmons and he question how Sheila was able to upgrade the base without any tools or arms. Simmons then concludes that if he could somehow determine the real truth, he could reconcile with Sarge. At this point, Sarge intervenes, knocking Grif out. Before Sarge can execute Simmons for treason, however, Church appears and knocks Sarge out from behind. Church mistakes the mostly blue Simmons as a Blue soldier native to the future. The Sacred Quest team finds itself in a swamp (Backwash), where Andy says they can rest and sleep for a while. However, with strong allusions to The Lord of the Rings, Caboose notices that something has been following them. Andy confirms that this Gollum-like creature has been following them since the beginning of their journey. Later that night, Tucker awakes to find that he is apparently alone in the swamp. As he begins to look for his companions, the mysterious figure approaches Tucker from behind (as he is being used as bait). The Alien ambushes the intruder, who turns out to be Tex. She then joins the team after being promised the sword upon completion of the quest.
