Burt's pumping legs struck Nell in the side. He spun forward and landed 
hard on the hallway floor, skidding for a short distance. This brought him to 
the feet of Harv, who had turned to face him and deployed his nunchuks. Harv 
went upside Burt's head a few times, but he was panicked and didn't do a very 
good job of it. Burt groped with one hand
and managed to catch the chain that joined the halves of the weapon. Nell had 
gotten to her feet by this point and ran up Burt's back; she lunged forward and 
sank her teeth into the fleshy base of Burt's thumb. Something fast and 
confusing happened, Nell was rolling on the floor, Harv was dragging her back 
to her feet, she reached back to snatch up the Primer, which she had dropped 
again. They made it into the emergency stairs and began to skitter down the 
tunnel of urine, graffiti, and refuse, jumping over the odd slumbering body. 
Burt entered the stairwell in pursuit, a couple of flights behind them. He 
tried to make a shortcut by vaulting over the banister as he had seen and done 
in ractives, but his drunk body didn't do it as well as a media hero, and he 
tumbled down one flight, cursing and screaming, now rabid with pain and anger. 
Nell and Harv kept running.
