Darkness was a funny thing, Emma realised. It could strike anyone and anywhere, no matter if the person had magic or not. It didn't matter about social status, Regina and Gold were perfect examples of this. It didn't matter who their parents were, Lily had shown that. Her parents were Maleficent and Merlin. Merlin who was the greatest Sorcerer in the world, who couldn't help his daughter.

So why Killian? Why had he sacrificed himself to save her? Why did he become the dark one? Why couldn't he let her become the Dark One? She was prepared to let everyone live happily, while she battled it. It was horrible. Regina had Robin, her parents had each other, even Gold had Belle and she was left with no romantic partner. It wasn't until now, she realised how important he was to her.

She hadn't even lost him, he was gone to darkness. What if he went to the darkness again? What if she lost the man she loved? She had only worked up the courage as he was about to be sucked in the darkness and he had just smiled and told her that he loved her.

Why didn't she tell him when they were in her room? It was the perfect moment and she knew that he knew what she was going to say but she chickened out. She was so afraid of losing him by her confession of love that she didn't say it and now she had lost him because he did love her.

His name was written in the dagger. Killian Jones. Not Hook. His real name. It made it all that much worse for her. She just wanted to hug him and never let go and she might never get the chance to do it. To never say she'll always love him. All of him.

'Killian,' Emma whispered.

'Where'd he go?' David asked.

'Unicorn land of course,' Regina said sarcastically, 'where else is that idiot?'

'He just saved your life Regina,' Emma said angrily, 'you might want to show more respect.'

'Don't you think I know that?' Regina asked.

'Should we summon him?' Snow asked.

'No,' Regina said quickly, 'he probably go and kill everyone in a ten mile radius that's related to Gold.'

'So everyone?' David asked.

'Yes, because somehow we're all related to that,' Emma sarcastically.

'He'd go for Belle first,' Robin said, 'unless he wants to get it over and done with.'

'But we control him,' Snow said, 'we don't need to worry about all of this if we tell him not to do it.'

'All Dark Ones want the dagger, who knows what Hook would do for the dagger?' Regina said.

'Killian,' Emma said, glaring at her, 'the man that saved your life is Killian, not Hook.'

'He saved both of you,' Robin said.

'Hey, what happened?' Henry said, running up to them.

'It's a long story,' Regina muttered.

'We have time,' Henry said, looking at them, 'or don't we?'

'We should ask the Apprentice more questions,' David said, 'see what else he knows about Merlin,'

'Merlin?' Henry asked. 'As in King Arthur, Guinevere, Violet and Lancelot? Those who live in Camelot?'

'How do you know them?' Robin asked.

'Old story books of course,' Henry answered.

'This might be what we need,' Regina said, 'to find Merlin. Who wants to read?'

Snow and Henry agreed and Emma turned to face the dagger. She should grab it. She was the only one who knew him well. Who better to look after it than her?

She stepped forward and Regina swung an arm out.

'What, Regina?' Emma asked angrily.

'Don't go near the thing,' Regina said.

'Why Regina?' Emma asked. 'Think I'm weak?'

'I think you're suffering from heartbreak, Emma,' Regina said.

'Why Regina?' Emma yelled. 'Because Killian just became the Dark One? Is that what you think? Or because he just sacrificed his happy ending for mine? Or because he just told me he loved me?'

'What do you think Miss Swan?' Regina yelled back. 'You think I don't know that? He didn't just give you your happy ending, he gave me mine!'

'I don't even know why he would!' Emma shouted. 'You aren't special- you aren't-'

Emma stopped as she heard the thud of- of horse feet? She looked at the dagger and swopped down and grabbed it and turned back around.

'Who the hell are you?' Regina asked, stepping forward.

'Is that anyway to be speaking to a King?' The male in the lead asked.

'You're in my town, and I'm a Queen,' Regina spat, standing up straighter.

'In this town?' Someone else asked. 'There's no one else here.'

'My name is Snow White,' Snow said, stepping forward, 'and you're in Storybrooke.'

'Snow White? From the Enchanted Forest.' The young girl asked, stepping down from the horse. 'Mother, father, this is the women I've been telling you about!'

'Why did Merlin send us here?' A grumpy voice asked.

'Merlin?' Emma asked. 'Tell us who you are please. We have questions and if you are who we think you are, then you could help us.'

'I'm Guinevere,' the lady dressed in an old fashioned dress that was a pink-purple, 'that's my husband Arthur, and that's my daughter Violet.'

'You're from Camelot right?' David asked.

'Yes,' Guinevere smiled, 'our friend Merlin sent us, with a message to you people.'

'About Kill- about the Dark One?' Regina asked.

'That too,' Guinevere admitted, 'but he told us to tell you to keep hope. That the one you loved will return to you sooner than later.'

'What else?' Emma asked.

'That we had to help you find this Dark One,' Arthur grumbled, 'he couldn't come. The lazy twat but we will.'

'No one has good information!' Emma yelled. 'Keep hope. Sooner than Later! The one you loved! I need good answers not fluffy answers from a bunch of royals who can't help me!'

'How do you know that?' The young girl, Violet, asked.

'I'm leaving,' Emma said, waving her hands in front of her. She disappeared in a cloud of white smoke and she reappeared at the Jolly Rodger.

'I was hoping you'd be here soon.' Emma jumped and turn around. There he was. Sitting causally on the railing of his ship, looking at his hook. He was different. His eyes were a hard blue, there was none of his kindness in them and his clothes seemed to reflect the Dark One. He wore tight black pants and a long black jacket that had small patterns on it.

'Killian,' Emma said softly, her grip on his dagger tightening.

'I'd thought you'd be here.' Killian said, ignoring her. 'The grief and all.'

Emma just stared at him.

'Why didn't you come back?' Emma asked.

'You don't trust me,' Killian laughed darkly, 'none of you do, especially the Evil Queen, but then again I saved her life. I saved yours as well.'

'Of course I trust you!' Emma said.

'But you don't trust the Dark One Emma Swan,' Killian smirked, 'no one does. Why do you think I've been trying to kill the Dark One? He can't be trust.'

'We all want to help you Killian.' Emma said sincerely.

'Emma why lie to me?' Killian said. 'They want to help you because you're emotionally unstable without me. What better way to help their Saviour then helping your Saviour?'

Emma tried to argue but she couldn't help but see some truth in his words. Her parents wanted her to be happy, Henry as well and Regina- she still felt guilty for ruining her family. Killian was a part of her family now and had been for longer than Emma liked to admit.

'See Swan,' Killian said, 'no one loves me expect you. Even then I doubt it. I can't beat any past lover of yours now can I? Being the Dark One has shown me.'

'Killian,' Emma said, 'please don't say that. That's not true. I love you. I love you more than anything.'

'Why lie Swan?' Killian yelled, getting off the railing now. 'No one could love me. Not Liam or Milah. Not even you.'

'I love you, Killian Jones,' Emma said, feeling a tear go down her cheek, 'I love you so much. It broke me to pieces when I thought you were dead. It was such a relief to see you again. When you were alive up in my room that I was filled with so much happiness.'

Killian walked to the middle of his ship and leaned up against the wooden pole. His eyes were staring at her, no emotion in his eyes.

'I suggest you leave Swan,' Killian said, 'I don't need your company,'

'But I need your company,' Emma said softly, walking towards him.

'No Swan,' Killian said, 'I can't have your company. This darkness. It's harder to contain then anyone of us could have thought. I've thought of going to hurt people in this town more times than usual in a mere fifteen minutes. Darkness is a funny thing Swan.'

'Killian,' Emma said, walking closer.

'I said no SWAN!' Killian yelled, lifting his hands. She felt herself hit the railing and she fell to the ground. She looked at Killian had come running towards her but had stopped a couple of metres away from her.

'Emma,' Killian said, 'I'm so sorry. I- I didn't mean it. I- just leave please. I can't promise you that I won't hurt you again.' He took a few steps backwards as Emma stood up slowly. She lifted her hand to her head and felt it bleeding.

'Killian I could never stop loving you,' Emma said, hiding her hand from his sight.

'But I could hurt you Emma,' Killian said, 'I won't take that chance love. Please just leave.'

'Killian,' Emma said walking towards him, ignoring the pain in his hand. His eyes darkened and he lifted his hand.

'I said leave Swan,' Killian said, flames appearing in his hand. Emma knew he couldn't control this darkness but she had to help him.

'I love you,' Emma said. The flame hit her right shoulder and he had his head in his hands as Emma healed her wounds quickly.

'LEAVE BEFORE I KILL YOU SWAN!' Killian screamed at her. Emma knew now was the moment to leave.

'Not before I tell you that I can help you.' Emma said.

'Don't use that dagger,' Killian said, 'it brings on the darkness.'

Killian had produced another fireball and Emma vanished in a puff of smoke. Her eyes were full of tears as she appeared in her parents' living room. She heard them talking outside the door and she quickly went to her room upstairs.

How could she help Killian if even he couldn't keep the darkness at bay?
