Summary: Spoilers For Season 4 Episode 17 - Best Laid Plans (and all episodes prior!)

Rumplestiltskin, along with the Author who recently joined forces with him, attempted to fill the Savior, Emma Swan's, heart with darkness. Her light (and her parents' trade off for the darkness to be put into Maleficent's child), blocked such an intrusion. To get his happy ending, along with the two remaining Queens of Darkness's (Maleficent and Cruella De Vil), he kills her, as she is what he believes stands in their way. In a fit of rage, Captain Hook kills Rumple with his own dagger before thinking about the consequences.

Now that everyone's favorite pirate captain is the Dark One, he is able to revive his love, but is the cost of becoming the Dark One himself too great? How will things change now that he is the Dark One?

Chapter One

Word was spreading that the Author had decided to team up with Rumplestiltskin, since he had been trapped by the good side, he wanted to cause a bit of mischief.

Emma Swan and Killian Jones, who was otherwise known as the notorious Captain Hook, were currently walking down the street heading towards Granny's diner for a quick bite to eat. Despite the impending danger of the Author helping Rumple and the Queens of Darkness turn Emma evil, the couple still needed to eat. They couldn't function on empty stomachs, after all.

Emma still hadn't fully made up with her parents, and after hearing Regina had known about this whole deal as well, Emma wasn't exactly on great terms with her either. Which meant, other than Henry and the currently bed-ridden August, her boyfriend was the only person she could turn to for aid and comfort.

Granted this wasn't a difficult task since she obviously enjoyed his company and he shared her feelings but still, she felt a wash of loneliness nonetheless. She had come to be used to the support of her parents, Snow White (Mary Margaret) and Prince Charming (David).

Currently, her arms were laced around his good one (the one without the hook for a hand), and her head was resting on his shoulder comfortably as they walked. He grinned down at her, his eyes filled with adoration for this beautiful woman. "Love, I know we need food, but shouldn't we be concerned about the fact that the Crocodile has got the Author to team up with him?" he questioned, his perfect, charming grin breaking just slightly.

Emma lifted her head off his shoulder and sighed lightly, "I suppose so." she didn't sound all that concerned, "But Killian, can we not worry about that right now?" she asked, and then chuckled lightly, "I'm starving."

He was about to nod in agreement, when he heard something behind them. Alarm bells immediately went off in his head and on instinct, and probably a bit of paranoia, he pulled Emma away from the street and into the nearest alleyway.

"Hey, what was-" Emma began but Killian put a finger to her lips and silenced her immediately. "Shh.." he sounded and looked over his shoulder. "Plan. Now." he whispered, his tone concerned. He felt it in the atmosphere. Something was up, and he knew by now Emma sensed it too from the way she was looking over his shoulder.

They wouldn't even have a chance to come up with a word of a plan again Mr. Gold and his gang because Killian's paranoia was definitely right this time. They had been spotted by the remaining two Queens of Darkness.

Rumple soon teleported himself into the alleyway, Cruella, Maleficent, and the Author sauntering in after him. "Looks like we've caught you, dearies." Rumple smirked cruelly and raised his hand upwards, ready to cast a spell and freeze the two.

Killian leapt forward to protect his Swan, but alas, he was too slow for Rumple's magic and was immediately pushed back into a nearby wall with a simple flick of the Dark One's wrist.

Emma could do nothing to stop him when he froze Killian in place. The pirate captain could still see and hear what was going on, as his eyes were the only mobile part of his body. He simply couldn't move a muscle from nose down, and therefore could not even open his mouth to yell.

The Author smirked, happy to be helping cause some mischief, and along with the two Queens changed his focus from Killian to Emma. Before she could raise her hands to defend herself with magic, Rumple had froze her as well.

Killian let out a silent scream of 'No!' in his head as Rumple began performing his magic, along with Maleficent and Cruella De Vil, on poor, frozen, Emma Swan.

The Author joined in the frightful sight last, raising up his magical quill and starting to write words in the air.

Maleficent and Cruella, after a nod from Rumple, disappeared to await the outcome and recieve their happy endings from the Savior with a darkened heart. It seemed they had done their part.

Killian's eyes flickered over to Emma, and their eyes met in a brief, urgent conveyance of the message 'I love you', something they both felt strongly in their hearts as the blue met the green.

Suddenly Rumple lowered his dagger and the Author stopped his scrawling. They both looked a bit dumbfounded. Befuddled, to say the least. "It didn't work?" the Author questioned, his tone extremely confused.

Despite still being a in a bit of a bad position, Killian's eyes glimmered with happiness. Victory. They hadn't been able to turn his love dark.

Rumple let out a hiss that caused the pirate captain's shining eyes to become worried rather than happy. "Of course it didn't!" the Dark One shouted, "You're the one who made her completely pure by forcing the Sorcerer's Apprentice to do Snow White and Prince Charming's bidding and cast all of the possible evil that she could've had into Maleficent's child! All of my plans are ruined. Ruined! It's all... your... fault."

The Author stared at him, noticing his cruel, twisted expressioned. "Wait... what are you doing?" he questioned nervously.

Rumple had raised his dagger, and all Killian and Emma could to was stare in awe at the scene playing out before them. "No! Wait! NOOO!" The Author yelled as he was pushed backwards and disappeared completely, probably sealed once more in his prison within the page.

Rumplestiltskin wasn't done yet, oh no. He was just getting started, and he was beyond furious. He turned towards Emma, and pressed the dagger against her neck. "I'm going to end your life, little savior." he snarled, and then moved his dagger down. Emma's eyes widened to the size of saucers and Rumple thrust it into Emma's chest, a quick, instant death.

That was the last thing Killian saw before he saw red. The freezing spell immediately was taken off her and she slumped like a rag doll to the ground, her green eyes staring up towards the sky, blood flowing freely through the wound in her chest.

Rumple looked down at his blood-soaked dagger with a smirk. The deed was done. The savior was dead.

"SWAN!" Killian yelled, breaking free of the freezing spell out of pure fury and sadness.

"You... how did you-?" Rumple looked at him wide eyed. No, that freezing spell should've still been in place! Had he been careless after killing the Savior? How could the pirate possibly have broken free?!

"How... dare... you!" Killian Jones seethed, his blue eyes ablaze as he pounced from where he stood, tackling and pinning the Dark One against a nearby wall. Soon enough, his hook was pierced through the other man's shoulder.

Rumple let out a gasp of pain and his grasp on the magical dagger lessened, his eyes going a bit wide. Now this he wasn't expecting. Raising his hand to push the pirate back with a burst of magic, it turned out he was too slow this time.

The pirate ripped the dagger from Rumple's hands, his fury hindering his conscious thoughts. He didn't think of the consequences. He was more enraged than he had ever been before. Even more enraged than when Rumple had killed Milah. This was the second time his love had been killed by this Crocodile. Enough was enough.

Teeth bared, he glared at the Crocodile he had hated for so many years. "You killed my love!" he snarled. This had been his true love. He loved Emma Swan more than anything. Even more than his beloved ship. He loved her more than the open ocean. She was his world, and this man had crushed it.

Rumple, despite himself, looked a bit frightened. He may still have had his magic, but he couldn't use it on Killian at the moment. Killian held the dagger. He was useless and couldn't do anything to save himself. He wiggled slightly, trying to get free of the man pressing him so roughly against the wall, but that only brought on another wave of pain from where Killian's hook was drilled into his shoulder.

With a mighty roar that could put a dragon to shame, Killian pulled Rumple towards him and then slammed him against the wall, jarring the older man quite a bit. All Gold could do was stare. He opened his mouth to speak but it was slick with blood, and some dribbled out of his mouth.

'Damn pirate must've slammed me against the wall harder than I first realized, must've cracked something...' Rumple thought to himself, and he gulped slightly, but the fear of choking on his own blood stopped him mid gulp and he took a deep breath instead.

He was petrified. He didn't want to die that was something he had always feared. He should've known he'd die a coward. It was how he had lived. He should've also known that this would be the man that would deal him the card of death. They had despised each other for so very long, and the captain had threatened to kill him many times over despite the consequences of becoming the Dark One himself.

He knew Captain Hook had lusted for this moment for so, so long. Killian had promised he would give up his vengance and try to be a better person, for Swan. But that had all changed when she was murdered in front of him by the crocodile himself. Feeling the blood drip down from the dagger and onto his hand, his love's blood, Killian snapped even further than he already had. He was back to being Captain Hook, an even worse, more demented version of himself, at least for now.

"You'll never hurt another person I love, or anyone for that matter." he hissed, his voice merely a dark, cold whisper. Without another thought, the pirate captain brought the magical dagger down into his long time nemesis's chest, driving it straight into the other man's heart.

He pulled out the dagger and stepped back, the Dark One's body crumbling to the ground before him, before quite literally turning into dust. Killian breathed heavily, his hand holding the dagger shaking as he realized what he had done.

Immense pain shot through him, but it most certainly wasn't as bad as the pain in his chest, filling his heart as he grieved for his Swan. Magic came up from the dust that had once been Rumplestiltskin and flowed into his body. It went into his veins and coursed through him like blood.

A shout came from him and he clutched at his stomach with his hook, causing a light graze against his vest. Tears appeared at the corners of his eyes and soon they were coming down like waterfalls. "Swan!" he cried out sadly, and still in pain, crawled over to her corpse.

"Swan!" he called again, mercilessly shaking her dead body, a hard task to do seeing as how heavy she now was, and the fact he was only using one hand. The dagger was still clutched in it as well, making the task all the more hard. His tears dripped down from his face as he laid her back down. They hit the still warm skin of her neck and face.

"I can't loose you... Swan... please..." he cried, and kissed her forehead, a small attempt to bring his love back to him. He brought up the dagger, it was still dripping with fresh blood. He watched as the name 'Rumplestiltskin' washed away, and was slowly replaced, in scrawly yet beautiful looking text, by two words. 'Killian Jones' which was partially covered by the thick blood of both his love and her murderer.

A last jolt of pain went through him and sobs wracked his body as he dropped the dagger down next to him, and hugged Emma's body close to him, his hand coming up and closing her dull green eyes. He didn't mind the blood smearing and staining his clothing.

"Please, Emma. Love... come back to me. We need you. I need you." he confessed, "I love you..." his voice was muffled by her skin as he had his face pressed into her neck, breathing in her scent for what he thought would be the last time.

Little did he know, golden sparks were flying off of his finger tips, sealing up the horrible wound in her chest and breathing life back into her body.

He felt her gasp against him and he immediately held her at arm's length rather then right against him, his blue eyes wide and anxious as he stared at her.

She had a coughing fit, her unnaturally dead looking green eyes becoming bright and filled with life once more before his eyes. "Killian?" she questioned between coughs. "What happened? You're covered in blood... where's Gold?"
