After discarding two of Sarge's suicidal battle plans, the Blood Gulch group invades O'Malley's fortress and are pinned down by mini-gun turrets manned by the Red Zealot and Lopez's head. Tex snipes Lopez's head off his turret, but the Zealot pins her down with gunfire. Simmons and Grif manage to enter the base and move on to look for O'Malley. Tucker, who had fallen into a hole near the windmill, finds a mysterious sword, and uses it to kill the Red Zealot. Meanwhile, carrying the bomb inside the fortress, Caboose mistakes Tex's "X" marking for a plus sign. He continues on and stumbles across a computer, from which he hears the voice of Church.
