Important! I changed the catagory of this story to Batman Begins/Dark Knight to suit the correct Batman universe, Nolanverse. So if you're new to this story, welcome! Review or I blow up your car. ;)

This is the final chapter of this story, but let me know if you want me to write a sequel of some sort, which is why I left the ending the way it is.

If you're new to this story also, check out my other Dark Knight fics, available on my profile.

PS. The black prisoner who intervenes in this chapter is based on the same prisoner who threw the remote out of the window during the boat scene in TDK. I like him. So I put him in.

The Joker stood up straight and cracked the muscles in his neck. He smiled, showing his teeth which were now stained with blood. Then he looked Doctor Crane straight in the eyes, giving such a terrifying look that Doctor Crane felt he might faint.

"That was a, ah, nice try you did there, Crane. But, ah, see…that shit doesn't work on me. I'm…immune, I guess" The Joker spoke slowly, as if he was trying to contain his anger. "But, if you want to, ah, get a guys attention that's not the way you do it"

"Y-you're not…mad?" Doctor Crane spluttered, shaking with fear.

"The Joker laughed softly, "Mad? No, I'm not mad, Crane."

Doctor Crane breathed a long sigh of relief. It was safe to say that didn't go well. But he couldn't help but wonder why the chemicals didn't work on The Joker.

"Why…why didn't it-" Doctor Crane began, but was cut off.

"Why didn't it, ah, work on me? Well, Crane, you're a man of science, what generally happens when you, ah, are exposed to too many chemicals? Hm?"

"You become immune to them." Doctor Crane's voice was just a whisper. He knew something back was going to happen now. He could feel it. He just wished he hadn't done that. He wished he had never bothered with The Joker now.

"Now, ah, Crane…tell me, because I'm, ah, curious…" The Joker begun, is voice full of tension, as if he was building up for something, like a lion builds up for the kill, "after finding out my, ah, 'greatest fear'" The Joker reached for a steel chair, "what did you plan on doing next?"

Doctor Crane opened his mouth, just as he was hit over the head with the chair. His vision blurred and he had a ringing in his ears. He was hit again, stronger and he fell to the floor, holding his arms up for protection. There were loud cheers and rants from the prisoners around him, encouraging The Joker to go further.

"You still haven't answered!" The Joker spoke; raising his voice as he rained the chair down on Doctor Crane twice more, first hitting him in the neck and then hitting him in the face. Blood began to drip from his nose and cuts in his head.

"I'm sorry! I'm sorry! Stop it, please!" Doctor Crane cried out as he desperately curled into the foetal position. He felt The Joker boot him hard in the back.

"You haven't answered! What were you going to do next?" The Joker yelled this time, hitting Doctor Crane with the chair as hard as he could, "Answer!"

All Doctor Crane could think about was protecting himself, leaving The Joker without an answer. He was yanked up by the cuff of his orange Arkham jumpsuit, and found himself face to face with The Joker. Doctor Crane was horrified at the expression of the clown, who was seething with rage.

"Answer. My. Fucking. Question." The Joker spoke softly into his ear.

Doctor Crane tried desperately to think of an answer, but before he could, The Joker interrupted him once more, "Were you going to experiment on me, hm? Try to use to 'fear' against me? I think it's safe to say you're plan didn't work out, huh, Crane?"

Doctor Crane was thrown against the floor, whilst The Joker continued speaking, "You know what happens to people who misbehave, Crane? They get punished." The Joker picked up the chair once more, and without pausing, rained it down on Crane with mercy.

"Guards! Someone!" Doctor Crane yelled as loud as possible, hoping to save himself. He saw The Joker raise the chair high above his head. Doctor Crane did all he could, raising his arms to protect himself. The chair was brought down and Doctor Crane felt the snap of his bone breaking. He cried out in pain.

"Look! The baby is crying! Does the scare crow want the nasty clown to stop?" The Joker taunted, as he rolled Doctor Crane onto his back using his foot. Doctor Crane looked up through his bloody face. The Joker stood on Doctor Crane's stomach, and moved one foot onto his throat. Doctor Crane began to choke, spitting out blood in a failing attempt to save himself.

A few of the prisoners who watched and encouraged before now began to calm down, as they watched Doctor Crane try desperately to shift The Jokers foot from his windpipe.

"Yo! Joker! Stop it, man! He can't breathe!" yelled one heavily build black prisoner, who moved forward to The Joker to try to intervene.

"Ah, ah, ah! He needs to learn his lesson," The Joker spoke back calmly. Doctor Crane by now had begun to stop moving as much, instead his eyes began to roll back in his head as felt himself getting weaker and weaker through lack of oxygen.

"Joker. Cut it out," The black prisoner called again, this time moving towards him in an intimidating manner, showing off his well build body.

The Joker ignored him, instead he crouched down and slapped Doctor Crane, "What's the matter, Crane? Can't take a joke, hm? I thought you wanted to play?" He received no answer from the now unconscious Crane.

The watching prisoners now decided they had had enough, as the black prisoner lunged forward, knocking The Joker off Doctor Crane. The Joker began to laugh hysterically as the black prisoner punched him in the face repeatedly.

"You sick son of a bitch! You killed him!" The prisoner yelled out, his knuckles covered with The Jokers blood.

The Joker just laughed harder, "This is like the Batman all over again!" he yelled during peels of laughter.

Suddenly, the prisoner was yanked off The Joker, as a dozen guards took control of the situation. He was heaved up by two guards who handcuffed him and dragged him away. Looking back, The Joker saw four nurses and two doctors surrounding the limp body of Doctor Crane.

The guards dragged him along down a corridor, which The Joker recognised as the way to solitary confinement. He was thrown into a cell, where the door slammed behind him.

"You're staying here clown, until you calm down" one of the guards told him through the door.

The Joker just yelled at the top of his voice, "You can't keep me in here! I'm never going to calm down! He was asking for it! That Crane is a big baby! The Scarecrow my ass! Let me out! I want out! I want out! I want The Batman!"

The Joker yelled himself hoarse for hours before running into the wall as hard as he could, smashing his head against the wall repeatedly. Blood began to pour down rapidly from his head, obstructing his vision, but he wouldn't stop. He battered himself up until two guards ran into the room, holding him down whilst he yelled as another nurse injected him with a sedation. The Joker spat into the guards face a mixture of blood and slime before passing out.

Doctor Crane woke up in a dizzy mood to find himself in the medical wing. He waited for his vision to steady before looking down as his left arm, which was now in cast. He raised his good arm to his face, and felt bandages wrapped around his head. He flinched as he applied some pressure to check how bad it was.

Not that bad he thought to himself. At least I'm alive; I thought he was going to kill me. He's crazy!

"Morning, sweet-pea" a familiar voice sung to him from across the room.

Doctor Crane sat up quickly, looking at the bed where the voice came from. He saw The Joker, with bandages covering his head in a manner similar to his own. Doctor Crane began to hyperventilate.

"My, my, whatever is the matter, Crane? Scared, are we?" The Joker smiled at him, revealing one of his teeth was missing, "You've got nothing to be afraid off. Unless you happen to have more of that air freshener on you" The Joker began to laugh hysterically, as Doctor Crane fell back down on his back, his eyes wide as he struggled to breathe.

"Ready for round two, yet?" The Joker continued, and Doctor Crane could take no more. He opened his mouth and screamed as loud as possible. Nurses rushed in and sedated him, as The Joker continued to laugh.

"Pff, baby," The Joker said to himself, as Doctor Crane became quiet. One of the nurses approached him, shaking her head with her hands on her hips.

"Chickie, you know that's not nice," she said to him.

The Joker shrugged, instead replying, "Fucking wimp. Can't even take a few hits with a chair!"

"You should know better, Joker. After all, you're supposed to be the 'sophisticated' one," She told him as she walked out.

"He started it!" The Joker yelled back childishly, folding his arms and pouting. Looking over at the unconscious Doctor Crane, The Joker smiled and said to himself, "Things are definitely going to be, ah, more…interesting, now."

Alfred walked through the newly rebuild Wayne Manor, carrying a breakfast tray and a newspaper. He walked into the bedroom where Bruce was sleeping. He placed the tray down at the foot off the bed and drew open the curtains.

"Rise and shine, Master Bruce" he said, handing the tray to Bruce.

Bruce sat up, and ran his hand through his hair, "Morning Alfred. A newspaper, why, is there something good in it?" He took hold of the paper, curious.

"I thought you might want to see it for yourself, Master Bruce" Alfred waited, as Bruce opened up to see the headline.

Deadly fight at Arkham Asylum said the headline, Jonathon Crane and Joker in bloody brawl

Bruce looked up at Alfred, who looked back with his eyebrows raised.

"Well, at least they've gotten acquainted with each other," Bruce said as he put the paper down next to him.

"I feel that The Batman may be needed in the future to sort them out," replied Alfred.

"I have no doubt about that, Alfred," said Bruce.
