Alicia and Rudy are aided out of the tunnels by a mysterious man wearing Greg's face as a mask. The man is revealed to be Castillo Sermano, who then orders a horde of zombies to restrain Alicia and Rudy in an attempt to kill them and use their flesh for his own purposes. Alicia and Rudy escape Castillo, blowing the tunnels up in the process. Castillo manages to survive the blast and Alicia gets into a sword fight with him. Castillo stabs her in the heart, and Rudy manages to decapitate him soon after. However, the still-alive headless body of Castillo begins to strangle Rudy. Alicia, who is barely alive, gets up and crushes the head under her foot, which finally kills him. Although Alicia seemingly dies, she and Rudy are rescued by a team of agents. The agents ask for Rudy's name, to which he responds with Rudolph "Curien". The ending narration reveals that Rudy gave Alicia the immortality serum. The two survivors return home.
