 Why does Gerri kiss Lane?
Raging , Trooper Lane hovered three thousand feet above Tammany Square. The cool cybrain surgically implanted in him was working on the problem. Just a little time off, so I shouldn't blow my top. The humming paragrav-paks embedded beneath his shoulder blades held him motionless above Newyork's three administrative towers. They don't teach them about their own city, that they'll be fighting for. Two black paragrav-boats whirred along the translucent underside of Newyork's anti-missile force-shield, the Shell. Lane somersaulted. Cybrain had taken charge of his motor nerves. A predatory excitement rippled through him as he sailed down through the air. Lane dropped lightly to the floor, inside the room, in battle-crouch. Tammany Hall has warned that this man is extremely dangerous. Citizens are cautioned to keep clear of him. Lane is an insane killer. Lane's mailed hand snapped open a pouch at his belt. The force-bomb "exploded"—swelled or inflated, really, but with the speed of a blast. It shaded the view from his window and re-entered the tower wall just below. Orange or green is the action. Nothing gets past, except maybe a full-size blaster-beam. "Gerri Kin. Look, Lane, holding me is no good. Me and my buddies, we just come back from fighting in Chi, Gerri. Gerri Kin said, "That's what the force-domes did. But also the road to the return to city-states. I wanna see the Mayor and find out why we can't have time off. The rounded black hulls of the two police paragrav-boats were nosing toward the force-screen. A loudspeaker shouted into the room: "Come out of there, Lane, or we'll blast you out." But you are too, to them. The police boats backed away slowly, then shot straight up, out of the line of vision. Far below, the long, gleaming barrel of a blaster cannon caught the dim light filtering down through Newyork's Shell. The cannon trundled into the Square on its olive-drab, box-shaped caterpillar mounting and took up a position equidistant from the bases of the three towers. Lane stared down to see a large crowd gathering in Tammany Square. There were white dot faces on the balcony that Gerri Kin had pointed out as the Mayor's suite. "Lane is holding the Martian Ambassador, Gerri Kin, hostage.
 She pities him.
 She pities him.  She is terrified he'll kill her if she doesn't.  She likes Lane.  He is trying to save her life.
