A/N: For anyone reading my other series: I have a half completed chapter for 'Like Mother, Like Daughter' so do not worry, that will be coming very soon, however I seem to have written myself into a corner with 'Surrogate Siblings' so I do not know when or if I will continue.

After 3 years of marriage, just the sight of Mary Margaret makes David smile from inside out, her very presence still like a light even in the darkest of days, her touch always an anchor and her kiss never fails to make his heart leap in his chest.

"Good day at work?" David asks as Mary Margaret slides into the passenger seat of their truck.

"Yeah, the kids actually behaved themselves today" she replies with a quick kiss on his cheek.

After 3 years of a relationship, they found each other and themselves, they discovered love together, they uncovered fears and helped each other overcome them, they realised hopes and dreams; fate weaving a path for them to travel together.

They stayed in the parking lot as usual for a little while, conversation easily flowing, music playing, and yet to David, the sweetest sound was Mary Margaret's laugh.

All was as it should be. Well, at least until the crash.

After 6 years together, it all went wrong.

The lorry came at them from behind with speed. The impact jolted David, rattling every bone in his body, and causing him to hit his head on the steering wheel. He lost consciousness for what could have only been a few minutes, the damage reduced by his seatbelt. However Mary Margaret had not yet got her seat belt on. She went flying forwards into the window and when David finally came back to his senses, he turned to see shattered glass, an inflated air bag and his unconscious wife covered in blood.

"Mary Margaret!" he called hopelessly over and over, hoping she would open her eyes but of course it was not to be.

He tried to move, to help her, get her out, do anything to save his love. But the movement was too painful and caused him to pass out once again.

As the darkness took over and his eyelids became heavier, he tried to resit, he really did. Unfortunately, for all love had brought this couple, it could not save them from the crash.

He wakes to the sound of a steady beeping, almost that of a heart monitor. Yet from what he can recall, he wasn't at a hospital. He was picking up his wife from the school. When the truck had hit and...

Mary Margaret.

Oh hell, Mary Margaret.

David tears open his eyes, blinking furiously. He sits up in bed, in what he can now see was a hospital ward, ignoring the rush of pain as he tears out the tubes and wires attached to him. The pain of not knowing if Mary Margaret is even alive, the last memory of her being a critical one, is by far worse than any physical pain David could feel.

He stumbles out of the ward and into a nurse.

"Sir, I recommend you get back into bed right now" she advised, placing a firm hand on his shoulder.

"My wife, Mary Margaret Nolan: where is she?" David demands.

A sombre mood suddenly falls over the two as the nurse drops eye contact and presses her lips into a thin line.

David feels a stabbing pain to his heart which was definitely not from his own injuries.

"No. She's alive, I know it. I have not lost her" David insists his head and heart both agreeing on this one. A steely assurance taking over which was something more than stubborn denial.

"Your wife is alive" the nurse confirms yet, still something was not right. The relief flooded over David causing his knees to weaken a little,

"David, this will be extremely hard for you to hear but I must tell you"

And just like that, 6 words can ruin 6 years together. An unbreakable couple, no longer so with 6 little words.

"She doesn't remember who you are"
