Killian Jones was standing in front of them, and he was the Dark One. Emma Swan, the other Dark One stood with her family. Killian was staring at them all in front of the clock tower with his hands raised, ready to attack. Ready to defend himself. And Emma could not blame him. She had made him the Dark One because she was selfish. She wanted Killian all to herself yet hardly taking in Killian's thoughts on the matter. He didn't want to be the Dark One yet here she was, carrying Excalibur with her name and Killian's on it. Well she was carrying the fake one and someone she didn't know had the real one.

'Killian please,' Emma begged.

'You don't get to talk to me Emma Swan.' Killian spat. 'You have ruined my life.'

'I tried to save you!' Emma said.

'By making me the Dark One!?' Killian asked darkly. 'By making me the thing I hate the most!?'

'Hook-' Regina warned and Killian turned on her, his eyes glaring at her. 'Can't you see how much see loves you? How much she's done to save you?'

'Emma wouldn't need to save me if it wasn't for you!' Killian spat, taking a few steps forward and Robin took his sword out.

'I don't want to use my sword but I will,' Robin warned. Killian's eyes scanned Robin with a cold calculated look that Emma didn't like the look of. That was the look of the Dark One planning something.

'And yet you will,' Killian said, 'what a shame your daughter will grow up without a father. Like how I grew up without a father. And I grew up perfectly.'

Killian held his hand out and Robin started to choke. Killian was glaring at Robin. All the hate he had as the Dark One was travelling through his magic and it was killing Robing. Yet they were all surprised. Killian had not shown any magical abilities and yet he was choking the life out of his best mate. It was then that Emma realised Killian's dark magic ran through his emotions, which wasn't a good thing for any of them.

'Robin!' Regina said and she turned on Killian. The look she gave him was terrifying. It was the Evil Queen. And Killian knew it. Regina conjured fire in her hand and Emma ran and grabbed her hand as Killian let Robin go to summon his own fire ball which didn't even look like fire. It looked black and cold.

'This isn't Killian,' Emma said coldly, trying to figure out a way to save Killian. He wasn't about to die. Not after everything she had done for Killian Jones.

'And the darkness has to be destroyed,' Regina spat. She waved her hand and the true sword that was Excalibur appeared in her hand. Before Emma could object, Regina stabbed Killian in the heart. Emma gasped and clutched at her chest. She could feel the darkness leaving her and she saw blood pouring from the wound that Killian had sustained.

'Killian!' Emma yelled. She felt her hair fall down her back and she saw herself wrapped inside a cloud of white. She was becoming the Saviour again. Her clothes had changed. She was wearing her red leather jacket and black jeans, her beanie on her head and her boots. The cloud vanished and Killian was holding his chest, his face pale white and everyone surrounded him.

Emma ran up to him and she held his hand, putting his head on her lap. His breathing was heavy and he was closing his eyes.

'Thank you- thank you Regina,' Killian gasped through his ragged breath.

'What!?' Emma asked, looking at Regina.

'He asked me to rid the darkness forever,' Regina said, 'by killing him.'

'How could you!?' Emma said, looking down at Killian.

'Your future was more important to me than my own,' Killian said, 'but I might need a little help being a survivor this time love.' Killian laughed and he started coughing.

'There has to be a way to save him!' Mary Margaret said.

'There isn't,' Gold said.

'You can't leave me Killian!' Emma said. 'We had plans. Our white picket fenced house. The promise of our future together. Operation Light Swan, remember?' Tears fell down Emma's face.

'I love you Emma Swan,' Killian said, slowly closing his eyes. 'I hope you find the white picket fence.'

'I won't give up on you,' Emma said, 'you never stopped fighting for me so I won't on you.

'Good… but Emma… Emma, please just let me go…please….you have to do this Swan…just let me go.' Killian said and his eyes started to fall.

'I love you!' Emma said, squeezing his hand.

'I'll see you again,' Killian said and he let go of her hand. 'Goodbye Emma Swan.'

And in that moment, Emma knew Killian's death would hurt her the most. She was just starting to know Graham, it wasn't love at that moment when he died but she still felt deeply for Graham. And Neal. It hurt more for the fact that Henry wouldn't have his father. She stopped being in love with Neal a long time before his death but Killian.

But Killian. She had time to fall in love with Killian Jones. She was still in love with Killian Jones and she'd be damned if she was going to lose him. She'd almost lost him once in Camelot and she wouldn't lose him. Not now when their future was so close.

'Megara you can't say that!' A voice said. Emma and her family looked around. There was a couple. About in their late teens early twenties.

'Hercules!' The girl spat. 'Do you want to live?'

'Megara,' the boy laughed and Regina, Robin, David and Mary Margaret took their weapons out as the couple approached them.

'Who are you two?' David demanded.

'Look at this Megara, people who don't actually know us,' the boy laughed.

'Who are you?' Regina demanded. 'Or otherwise you can be a roasted sandwich.'

'If you insist,' Meg said, 'we are here to escort you to the underworld. Well not you all just that very attractive man over there.'

'NO!' Emma yelled. 'No! You will not take Killian,'

'Emma, sweetheart,' Mary Margaret said, resting a hand on Emma's shoulder but Emma shook it off.

'No! There is a way to save him!' Emma yelled and she looked at the young couple. 'You know there is! There is a way isn't there?'

The girl, Megara, she looked at the boy, Hercules, and she sighed.

'Before a person is declared "dead" they go to the underworld, to the souls of the departed.' Meg said. 'Where Hades-'

'Hades?' Belle asked and Megara looked at her.

'They might know us after all,' Hercules said.

'Hades is lord of the Underworld, ruler of death,' Belle said.

'Sounds like he gets out a lot,' David said, 'so you think Hades can help us?'

'Perhaps,' Megara said, 'but first you must speak to the soul of the departed to see if they wish to be saved. If they don't want to be saved, you can't save them.'

'What's the price?' Robin asked and Megara and Hercules looked rather confused.

'Price?' Hercules asked.

'All magic comes with a price,' Gold said.

'There isn't a need to worry about that,' Megara said dismissively, 'but I can get the potion ready now so you can speak to him.' Megara looked at Emma with understanding etched in her eyes. Emma knew this was because she knew how it felt to lose someone.

'It will work?' Emma asked.

'Yes,' Meg said.

'What about his body? Regina asked.

'It will have to go down to the underworld,' Hercules said and before anyone could object, Killian's body vanished and Emma was left sitting next to nothing, her hand covered in Killian's blood.

'No,' Emma whispered, 'no! Bring him back!' Emma stood up and stepped towards the couple. David placed a hand on Emma's shoulder and Emma glared at him.

'I have some potion here,' Meg said, seeming unfazed by Emma's outburst, 'do you have something of his?'

Emma looked right hand. Killian had placed the ring back in her hand. She nodded slowly and she put the ring out, and Megara nodded. She handed Emma the potion and Emma hesitated. What if he didn't want to come back? What if he didn't want a future? She shook her head. She couldn't think like this! She poured the potion on the ring and she looked behind.

There he was, smiling at her, and his eyes shining blue like the ocean. Emma ran up to him and hugged him. She was surprised to see that she was able to hug him.

'You're back,' Emma said, holding his face with her hand.

'Swan, I'm not really back,' Killian said, 'I'm in the Underworld. It's- well- full of dead people and it only brings back memories of my brother.'

'I can save you,' Emma said.

'Emma Swan, I love you but I'm here with Liam,' Killian said, his eyes brimming with tears, holding her face. 'And my mother.'

'But I need you,' Emma said, 'you are my Saviour.' Killian looked at Emma. All Emma could was love and sadness in his eyes. But there was something else. Fear.

'Then save me,' Killian said and Emma watched as he slowly disappeared.

'I'm bringing back the happy endings,' Emma said, putting on the ring necklace, 'and I will not give up on you. On us.'
