They zoom upward in hot pursuit of Zam as she fires out the open window at them with her blaster pistol. Anakin deftly moves in and out of the oncoming traffic, across lanes, between buildings, and miraculously through a construction site. Zam continues firing at them. They barely miss a commuter train, then race through a line of cross-traffic made up of giant trucks. The speeders bank sideways as they slide around right-angle turns between buildings. Zam races into a tram tunnel.
"Wait! Don't go in there!," Obi-Wan warns. Anakin zooms into the tunnel, but they quickly spot a tram coming at them. They brake, turn around, and race out, barely ahead of the charging commuter transport. "You know I don't like it when you do that!," Obi-Wan shouts over the roar of the commotion. "Sorry, Master," Anakin offers a quick apology before continuing. Zam turns into oncoming traffic, deliberately trying to throw the Jedi off. Oncoming speeders swerve, trying to avoid them, then Zam does a quick, tight loop-over and ends up behind the Jedi. She is now in a much better position to fire at them.
To avoid being hit by the laser bolts, Anakin slams on the brakes and moves alongside Zam. She now fires point-blank. Obi-Wan thrusts his hand out, using the Force to knock her speeder off-course, which allows Anakin to slide underneath her speeder. They race along in traffic, one speeder right on top of the other. The bounty hunter skims over the rooftops, causing Anakin to drop behind. He goes through his gears, zooming around traffic. They race at high speed across a wide, flat surface of the city planet. A large spacecraft almost collides with them as it attempts to land. They round a corner and clip a flag pole, which sends sparks shooting form the underside of their speeder. They spin out of control and Anakin manages to bring them to a stop, barely avoiding a collision with the side of a building.
"We've lost him," Obi-Wan seems disappointed.
"I'm very sorry, Master."
"You're not focusing. You're allowing your feelings to control you."
"Yes, Master."
"Now, concentrate. Can you sense where the assassin might have gone?"
Anakin clears his mind for a moment, then looks below the speeder, briefly telling Obi-Wan, "Excuse me for a moment, Master."
Anakin jumps out of the speeder. Obi-Wan looks down and sees Zam's speeder about five stories below them cruising past. Anakin miraculously lands on top of the Bounty Hunter's speeder and it wobbles under the impact. Zam takes off, and Anakin slides to the back strut and almost slips off, but manages to hang on. He works his way back to the speeder's cockpit, just as Zam stops suddenly, and Anakin flies forward to the left front fork. Zam shoots at him and a single bolt breaks off a piece of the speeder. Anakin slides to the right fork of the speeder, where he can't be reached. He scrambles to the top, holding onto an air scoop.
Meanwhile, Obi-Wan has jumped into the driver's seat of his speeder and is deftly gaining on the rogue speeder. The two speeders dive through oncoming traffic and then through cross traffic. Finally, Anakin is able to get hold of his lightsaber and starts to cut his way through the roof of the speeder. Zam starts firing at the helpless Jedi, knocking the sword out of his hand. Obi-Wan races under the speeder and casually catches the Jedi weapon in the passenger's seat.
Anakin sticks his hand into the cockpit and, using the Force, pulls the gun out of Zam's hand. She grabs the Jedi's hand, and they struggle for the weapon. It goes off, blowing a hole in the floor of the speeder. The speeder careens wildly out of control. Just as the dragster is about to nose dive into the ground, Zam pulls it out, and it slides hard on the pavement in a shower of sparks. Anakin goes flying into the street.
Zam exits the crashed speeder and runs. Anakin picks himself up off the pavement and runs down the very crowded street. It's the seedy underbelly of the city. Broken sidewalks, garish lights reflected on the filthy puddles. It's pretty crowded with various low-lives, panhandlers, and upper class slummers. Anakin barges into several of them as he chases after the fleeing Zam, but soon loses her in the crowd. There is a sudden swirl of litter from downthrusters. People start moving out of the way, and the open speeder lands in the street beside him. Obi-Wan gets out and walks over, holding out Anakin's lightsaber.
"Here. Next time try not to lose it."
"I'm sorry, Master."
"A Jedi's saber is his most precious possession. This weapon is your life!"
"You're right, Master. I got angry and I didn't focus properly. I lost track of the assassin."
"As I was landing, I saw her go in there," he points to a nearby club.
"I'll find her, Master. I won't let you down."
"Sometimes I think you'll be the death of me."
They go inside and several sketchy figures eye them suspiciously. "Split up," Obi-Wan heads for the bar. Anakin moves into the room as alien faces look back at him with hostility, suspicion, and invitation as he moves among the tables. Obi-Wan arrives at the bar and seemingly waits, keeping one eye toward the crowd behind him. Somewhere in the room, a hand moves to a pistol in its holster and unsnaps the safety catch. At the bar, a glass is placed in from of Obi-Wan. A drink is poured. He lifts the drink, but holds it. The gun is drawn from its holster and held down out of sight. Zam starts to move toward the bar and aims directly at his back, but suddenly Obi-Wan turns fast. His lightsaber flashes. There is a shrill scream and Zam's arm hits the floor. The gun drops from its twitching fingers. Blood spreads. The room is silent and Anakin soon joins him. They lift Zam and carry her out into the alley and lower her to the ground.
"Do you know who it was you were trying to kill?," Obi-Wan asks.
"The Senator from Naboo," the reptilian alien sneers.
"Who hired you?"
"You think I was the only one they hired?"
"There are more bounty hunters?," Anakin shakes her, "How many are there?"
There is a sudden whistling in the air and she twitches. Zam blinks in surprise and swiftly dies. Obi-Wan and Anakin turn their attention to the projectiles origin and briefly see a man in Mandolorian armor fly into the sky on a rocket-pack. Obi-Wan removes the dart from Zam's neck and examines it carefully, "Toxic dart."
