Thank you for the suggestion oncerSM, so this flashback will be mostly based off of season 5, but with a better Captain Swan ending if you know what I mean.

Flashback

"We went to Camelot for you, how did we disappoint you, and what do you mean this is all for me?" Killian asked as he threatened to throw the squid ink at Emma.

"I'm doing this for us, I'm getting rid of the darkness. Why can't you be happy? Isn't this what you wanted?" Emma replied.

"I want the darkness out of you, but you can't kill Zelena to get rid of it."

"This is the only way."

"No, there has to be another way. We went to Camelot to find Merlin, where is he? He has to be able to help you."

"He can't help us."

"Why can't you just tell me what happened in Camelot? Emma, please give me back my memories." Killian yearned.

"I can't, I'll lose you if I do."

"I will always love you Emma, no matter what."

"I turned you into what you never wanted to be, and you loved it. Killian, we did horrible things together, and I didn't want you to hate me for it."

"You're not making any sense. What can't you tell me?"

"You're a dark one," Emma said, and then Killian's name appeared on Excalibur.

"What? No, that isn't possible, there can't be two dark ones."

"You want your memories Killian? Here," Emma said as a dream catcher appeared in her hand. Memories started flashing in the dream catcher, and slowly Killian's face turned into a dark grin. He remembered the way Emma and him crushed Merlin's heart. He felt Excalibur's cut like it was yesterday, and he remembered feeling the blade cut his skin. He saw the way he begged at Emma not to turn him into a dark one, but she field of pink roses, Merida's heart in Emma's hand, choosing the home he stood in for Emma.

Killian wanted to cry, but the darkness told him not to show weakness. He was powerful, and Emma didn't tell him. They could've had fun and been like they were in Camelot. He had no regret of killing Merlin and by the way Emma looked, she didn't either. They burned a village down together, they tortured Merida together, and they planned for their future in Storybrooke together.

"You could've told me love. Just because I'm a dark one wouldn't mean I would stop loving you. Now I can do what I was never able to do," Killian said honestly.

"What's that?"

"Get my revenge."

"Do you have it?" Emma said.

"Yes love, of course I have it." Hook said as he appeared in red smoke. In his hand was the wizards boney wand.

"Good, now we can get rid of this town. We can live together in a castle in the Enchanted Forest and rule it, and you can get your revenge."

"Let's start."

Grey and red smoke enveloped the little town Storybrooke. Nobody knew what it was, what it meant, or what was coming. All Regina knew was that it was dark magic, and it had to be Emma. Regina quickly teleported herself to Emma's house, "Emma!" Regina yelled.

"Come in," Emma said and the door magically swung open.

"Emma, what are you doin-" Regina started.

"Killian. What are you doing here?" Regina ended.

"Why don't you just have your memories back instead?" Killian said making a dream catcher appear in red smoke.

"M-magic," Regina started, but then she was flooded with memories. She finally knew what Killian was doing here with Emma, he was a dark one also. He was turned into a dark one by Emma.

"No, what are you doing? What have you done? You enacted something, but I'll do whatever I can to stop it," Regina said.

"Love, this town is going to be destroyed, and then we'll all be in the enchanted forest." Killian said.

"You, you want your revenge on Rumpelstiltskin don't you? I may not be able to stop this curse, but I can make sure you won't know where he is when we get sent to the enchanted forest," Regina stated defiantly.

Regina quickly casted a spell to make sure when everybody reached Storybrooke Emma and Killian would temporarily not be able to move or do anything for an hour. Everything was covered, Regina was knocked out. She woke up again and found herself in the Enchanted forest standing next to all the people of Storybrooke. Regina quickly warned everyone what happened, and they all fled. Only Killian and Emma were left, and the couldn't do anything. Time moved by, but it didn't feel like anything for Killian and Emma, time was now irreverent to them. Finally, an hour passed and Killian yelled, "The damn evil queen. She's going to regret what she did."

Emma held Killian back and said, "Don't forget what we came here to do, why we sent everybody back to here. Let's find ourselves a home, and then we can start.
