So this is post S5 Episode 8 "Birth"

"For someone who has never been in love you're quite perceptive." His voice echoed in her head. She remembered the first time she met him. She hated him back then. He would make her realize truths about herself that she didn't want to realize. And she definitely did not trust him.

She remembered his smile when he said, "I don't mean to upset you, Emma, but I think we make quite the team."

It was a different smile then those she would receive later.

"It's what the kiss revealed." He had admitted his feelings for her when she didn't feel the same way. She still felt she couldn't trust him.

"When i win your heart, and i will win it, it won't be because of any trickery. it will be because you want me."

It wasn't until later on when he had joined her on her accidental adventure to the past did she realize she was starting to have feelings for the pirate.

He had insisted that leaving to New York would mean she'd keep running away from her problems.

He was the whom she shared her first ball dance with and afterwards when they were back home they had kissed.

A real kiss. That meant something to both of them. For her it wasn't the fact that he had traded his ship. It was because she has come to the realization that he was trustworthy and he would be there to support her in everything. And he was.

It would have been nice to have a calm start of relationship but of course that was hard in Storybrooke.

In the 6 weeks when everything in Storybrooke was calm it almost seemed like a happy dream. She'd get up in the morning ready for work walk outside to find him with her tea and his coffee. They'd kiss good morning and walk towards the library where he was working with Belle. He would always remember to kiss her head before she walked off and he'd whisper "See you later, love" in her ear while grinning at her. Later at night they'd have a date night either alone or with her family and it was always a nice time.

Sometimes at night they'd sit by the docks and have conversations that would go on forever. She'd talk about her past and he would talk about his. Neither would ask questions. They just understood. Sometimes their conversations were silly such as when she made fun of him.

"You don't know what a selfie is? Where have you lived the past years?" Emma would tease.

"Come on. What is it then?" He asked.

"Take out the phone I gave you."

He pulled the phone and handed it to her.

"Alright so you take the camera and you push here see so now the cameras pointing towards us. And if we take a picture..." She pressed the button. The screen now showed them smiling and she gave him back his phone.

"That's a selfie."

"It should be called the best picture ever. A dashing pirate and a beautiful princess."

She rolled her eyes.

"Can you teach me another thing?"

"What?"

"How do I make my phone show this picture when I turn it on like you have the picture of you and Henry?"

She looked at her phone and realized he was talking about the lockscreen.

"Here." She took his phone.

Now whenever he looked at his phone it had their two smiling faces.

"I will always chose to see the best in you."
"And I you"

The memory flashed followed by another of them, her arm wrapped around his and her head on his shoulder as they took one of their evening strolls.

Then to when he confessed that she was his happy ending and he was afraid of losing her.

There was the memory of meeting his shy cowardly self and then teaching him how to fight. His little nervous smile had made her laugh then the scene changed to a memory of him falling to his death as he sacrificed himself for her and Henry in the alternate universe.

And of course the great feeling of joy and relief as she found him alive and well back home.

"How many times do I have to tell you, Swan. I'm a survivor"

"It's all in a day's work for a hero." He simply smiled as she placed her forehead on his so relieved. He was still here.

More flashes of his smile as they danced together at the Camelot ball. As they kissed in the meadow. As he assured her that he was sure they'd get back to that white picket fence life they had talked about before.

"You got a pierced eyed pirate that loves you."

"Love has been all too rare in your life."

"Don't you know Emma? It's you."

"I assure you the future is nothing to be afraid of."

His voiced echoed through her head of the many things he had said to her.

She stared at the cut on his neck that was slowly pulling him away. Soon Killian would be gone.

"You have to let me go." He barely said.

But when he said those words everything flashed back to all the memories. All she could think about is how she would never survive without him. She had lost almost everyone and she was not gonna lose him. They had gone through too much and he meant too much. Before there hadn't been a chance to save the others.

"Everyone I have ever been with is dead. Neal, Graham, even Walsh. I lost everyone." Her own voice echoed.

Now here was her chance. He could live. It didn't matter if there were two dark ones. They could conquer it together.

That is why she did it. This is why she had done the greatest selfish deed.

She couldn't let him go. She needed him to fight as he always did and stay by her side.

"I can't lose you too." Her voiced echoed again.

When she saw him take a final breath and slowly close his eyes she knew. He'd be gone forever. There would never be another lover. She wouldn't be able to find anyone like him.

She knew she had to do it.

That's why Emma did it.

I know you're still in there Killian. You might not want to forgive me for what I did. I know it was a terrible thing to do but it my mind there was no choice.

Come back to me. Together we can rid ourselves from this darkness.

I love you. Even if you don't want to see me right now, trust me. I will find a way to save you. To save us.

From Emma.

A letter from Emma to Killian. I wonder what that response letter would look like hahaha. Anyways I hope you enjoyed. Feel free to leave reviews :)
