This is a moment I wondered about for some time...
So I decided to give it a try myself.
The first chapter is from Sam's POV and the next from Diane's.
Well, hope you like the first bit...Review are always appreciated!

He could still feel the imprint of Jack Dalton's fist around his eye. It was a quite hard punch he had received, but he could still see through his left eye though.
"Are you sure that you're alright?" Diane asked as she turned her look to check out the blue spot around Sam's eye.
They had reached the end of the airfield after a tense night where deep feelings and emotions were let out, and they were now desperately trying to spot a cab.
"Yeah, I'm sure. You shouldn't even be worried about me, but Jack."
"After what a cruel and unacceptable thing he put us through tonight, I don't care one single bit about whatever happens to him later on."
"Yeah, what was he thinking of?" Sam nearly yelled, still angry about the previous episode.
"Putting us to think that this would be our last day on this earth," Diane continued.
"I mean, seriously, it got me thinking. There's so many great things in life that I haven't even got the chance to experience a yet, and I felt like all those opportunities were taken away from me when we thought we were facing death!"
"Mhmm," Sam said looking away.
That episode in the plane kept popping up in his mind.
"Sam, hold me!"
It had all been chaos, but that moment where Diane embraced him, something clicked in his mind.
He found himself wondering what made him say those things out of the sudden. Could it really be that because the plane was about to crash and life about to end, he had to tell her? He would normally not just blurt out such deep feelings, but something just seemed to snap at that moment, he thought everything was over. He knew that when the plane would hit the ground, he would never see her again. And that made him say it.
"It would have been us these days, huh? You and me married?"
Stupid thing to say, he had thought to himself until he heard her response.
"Yes, little Sam's and Diane's running around?"
Did she mean what she said? He knew that what he had said wasn't a lie.
What was he saying? He wanted to marry her? As much as he had denied it over and over he finally gave in.
Yes, I do, and I've known it for a long time.
His thoughts returned to her response. If she had meant what she had said why hadn't she tried to talk to him about it afterwards? Was she, like him, afraid to get rejected by the other one? To be told that whatever was said didn't mean anything because they were about to crash? Or did she just say it because she wasn't clear in her mind at that time? Maybe she hadn't considered what she would response.
But as he looked back, he remembered how she had looked out of the corner of his eyes.
Somehow, she had looked relieved. Like she had waited to hear that kind of thing from him in a long time.
But everytime Sam had ever thought about telling her his true feelings when they weren't together, he had always imagined that she would laugh in his face and tell him that she didn't feel the same way.
He was afraid to open himself to her, especially after their breakup. He was afraid to tell her those kinds of things because then he would be vulnerable. And then again? He knew Diane. He knew that she would never hurt another human on purpose. She wasn't like he had been at the end of their relationship.
But just the thought of her knowing that he loved her, but that she didn't love him back was too big a risk to take. She had to break the ice between them before he could be vulnerable to her.
But what if she never does?
He turned his head to look at her and realized that her mouth was closed and that they had just been walking in silence the past minutes.
Why isn't she talking? Did she say something which I haven't responded to?
He saw the top of a cab and waved with his right arm.
"There's a cab," he said and poked her to get her attention.
A distracted Diane turned her head.
"Oh," she said.

Sam caught the cabdriver's attention and he pulled in.
"Come on! We better hurry before some others take it."
"You're probably right."
