"What are we going to do?" gasped Harley, as she and Jack hurried into the factory. It was pitch black, except for huge vats of green liquid which gave off the sickly glow, and illuminated vague shapes in the shadows.

"We need to find a vantage point so we can get the jump on him," retorted Jack, looking around for a good place to do so.

"Is he still following us?" asked Harley, glancing back.

"Of course he is," retorted Jack. "He's a psycho stalker. The only way to stop him is to kill him," he muttered, checking the barrel of his gun. There were only two bullets left, which Jack assured himself was enough to kill the Batman.

"C'mon," he said, climbing some stairs that led up to the platforms hanging above the vats.

"Are you sure it's safe?" asked Harley, looking skeptically at the chains. "They don't look like they'll hold much weight."

"Which one of us are you calling fat?" he chuckled, turning to her with a grin.

"J, how can you joke at a time like this?" asked Harley.

"Hey, I'm a clown, remember?" he said, gesturing at the makeup on his face. "And what else can you do when you're being followed by a joke of a vigilante in a Halloween costume?"

Harley didn't smile, so he sighed, climbing onto the platform and jumping up and down on it. "What are you doing?" gasped Harley, terrified.

"Showing you it's safe," he retorted. "Come on," he said, holding out his hand for her.

She tentatively took it, following him up the stairs and onto the platforms. "Are you sure you can hit him from this high up?" she asked, looking toward the door.

"No," retorted Jack. "But if my first shot misses, he'll come straight for us, and then I'll hit him with my second."

He put his finger to his lips as he suddenly saw a shadow fall upon the doorway. He squinted through the darkness, trying to separate the Batman's shape from the shadow.

He was suddenly blinded as a million lights flicked on – Batman had clearly pulled the switch to activate the factory's power. Jack swore as he fell back, his vision a blur, and when his eyes had adjusted to the light, he saw a dark shape heading straight for him.

Batman kicked Jack straight in the chest, knocking him against the railing and winding him, and sending his gun spinning across the platform. "It's over, Napier," said Batman, standing over him. "There's nowhere to run."

Jack looked over to see what he hadn't been able to see in the darkness – the platform he was on ended abruptly, leaving nothing but space between him and the glowing vats below. The only way off the platform was the way he had come, the way now being blocked by Batman.

But then Jack saw Harley slowly reaching for the gun, her hands shaking as she raised it carefully up. Batman had his attention focused on Jack, so he didn't see Harley aiming at his back. She gulped, took a deep breath, and fired.

Batman roared in pain as the bullet hit him in the side. He dropped to his knees as blood seeped from between his fingers. Jack seized the gun from Harley, aiming it at Batman's head.

"Don't, J!" cried Harley. "You don't have to be a murderer again! He can't follow us now! Let's just get out of here!"

Jack nodded slowly, lowering the gun. He headed past Batman, taking Harley's hand and heading back the way they had come.

Suddenly, something zinged past them, hit the stairs, and exploded. "What the hell?!" shouted Jack, shielding Harley protectively from the blast. He turned to see Batman holding up some kind of gadget which had just launched the explosive. "Are you trying to kill us?!" he roared.

"No," gasped Batman, glaring at him. "I'm just not letting you get away. There's no way you can escape now – we're all going to wait here for the police to show up. They're on their way," he said, holding up a communication device on his sleeve.

"You son of a…" began Jack, advancing toward him with the gun again.

"J, no," said Harley, grabbing his hand and looking at the ceiling. "There's a way out."

Jack followed her eyes to see a ladder high above them, leading to a skylight. "How are we gonna get up there?" he asked.

Harley nodded upwards, and Jack saw that directly overhead of them hung several long, thin fluorescent lights. "It's just like a trapeze," she murmured. "I'll swing us over."

"But I thought you said after what happened to the Graysons that you were too afraid to do that again," said Jack.

"I don't have a choice, do I?" asked Harley. "It's either that or you get arrested and taken away from me. And I'd rather face anything than face that."

Jack smiled and kissed her. "I have faith in you," he murmured. "Go get 'em, kiddo."

Harley nodded, taking another deep breath as she tentatively climbed onto the railing. She tried not to look down at the swirling green chemicals beneath her as she reached up for the light.

"I got you," said Jack, holding her around the waist as she reached up to catch it.

"Boost me up a little," said Harley. He obeyed, and she caught hold of the light, pulling herself up onto it. She swung her legs over it, and then held out her arms for Jack.

He took her hands, and she gently began to swing. "Do you think you can catch it?" she asked, as she swung him up closer and closer to the ladder.

"Yeah, just a little further," he said, reaching out a hand which could almost grasp the bars. Harley obeyed, swinging harder, and Jack caught hold of the ladder. He jumped onto it, and then held out an arm for her. "C'mon, kid," he said. "Jump."

Harley's heart was racing in terror as she swung over the giant vat, and the ground about a hundred feet below. She met Jack's eyes, tried to find strength in them, and suddenly let go of the light and jumped.

It was at that moment that Batman had, with much difficulty, managed to reload his explosive device, which he suddenly shot upwards toward the skylight. The theory was to destroy the top of the ladder, so Jack and Harley wouldn't be able to reach the skylight, and would be trapped until the police arrived. And to his credit, his shot was very accurate, hitting the top of the ladder and exploding it. Unfortunately, the impact of the explosive occurred just as Harley landed on the ladder, causing it to jolt, and causing her to slip out of Jack's grip.

"No!" shouted Jack, desperately trying to grab her. He failed, but she succeeded in grabbing the bottom rung before she fell. But in his panic, Jack had lost his grip on the ladder completely, and suddenly tumbled downward toward the glowing green chemicals below.

Harley watched in horror as, for the second time in a short period of time, she saw someone fall to their death. But this time it was someone she loved, which made it a million times worse. She could hear herself shrieking, but it seemed to come from a long way off, as she watched the man she loved plummet down, down, down until he hit the chemicals with a splash. The image of his clown face as he fell, his painted smile frozen in shock and horror, would be the last she ever saw of Jack Napier.
