ethan and krieger crawl quickly through the ducts, moving horizontally now. they reach a juncture and turn right.
ethan and krieger reach a ventilator shaft in the duct. a laser net protects the ventilator, red shafts of light cris- crossing every which way. ethan looks down, through the net.
in the duct, ethan signals to krieger, making a triangle of his hands. krieger wriggles forward and hands him a multi- sided, pyramid shaped glass object.
krieger holds the rope, his jaw clenched, sweat breaking out on his forehead.
krieger sees the predicament.
krieger shakes with the strain of holding the rope. his eyes suddenly widen as he sees something next to him.
ethan throws smoke cannisters and he and krieger crawl frantically back through the duct, the way they came.
