Author's Note: The prompt was "someone makes a wish and it goes wrong (or right)."
Make a Wish
At the age of five, a young Owen Hunt wished for a G.I. Joe action figure to complete his army of various sizes and species. After all, his platoon needed a leader if they were going to conquer their mortal enemies – his sister's Barbie dolls.
At the age of eleven, Cristina Yang wished for a new pair of ballet shoes. She had beat out her fellow ballerinas for the solo. And if she was going to do Clara justice in The Nutcracker, she was going to need some new shoes.
...
Even though he was far too cool now for elaborate birthday parties, Owen's mother insisted on inviting all his friends to celebrate his birthday. At the end of the day, Sarah Hunt brought out the same chocolate cake she always made for this occasion – each year adding a candle – and instructed her son to make a wish. He wished for a new car to replace his father's hand-me-down truck.
Standing outside her mailbox, Cristina closed her eyes as she inserted the key into the lock, desperately wishing for a thick envelope from UC Berkeley with a letter inside saying that she had been accepted into their graduate school.
...
As Owen sat silently in his seat on a flight back home after his second tour in Iraq, he contemplated what he was going to tell Dan's wife. He subconsciously patted the pocket of his army uniform and felt the heavy weight of Dan's ring, wishing for this day to end and the pain to go away.
Curled up in the middle of the bed with Meredith's arms tightly wrapped around her and with her wedding dress still partially on, Cristina tried to stop the seemingly endless stream of tears that flowed down her cheek. She shut her eyes so as not to see the brutal truth of the empty apartment around her. With all her might, she wished she could turn back time and make things right.
...
Owen could still feel the touch of Cristina's lips on his as he finally made his way to his mother's house. He wasn't one to go around kissing random women, but there was just something about Cristina that made her impossible to resist. And he just knew that he would have regretted not doing so before he had to head back to Iraq. Owen smiled and made a wish on a passing star that they would meet again.
Cristina lay in the semi-comfortable bunk bed in the on-call room and thought about Owen. How he was completely different from the man she'd first met – the man that had not yet lost nineteen of his fellow comrades in one fell swoop. "…but now I'm living in the after." Cristina sighed and wished that they were living in the before.
...
Bursting with joy, Owen grinned as Cristina said, "I do." All else ceased to exist for him as he placed the platinum wedding band on her finger, next to her engagement ring. And he wished his father could've been here to see his son get married and meet the woman who now wore his mother's ring.
Secure in the warm embrace of her husband, Cristina reveled in the sensation of being free from the fear and stress that had plagued her since the shooting. She had been completely honest when she'd told Owen that she felt better. And for the first time in a long while, she was genuinely happy. Not wanting to let go of this feeling, Cristina wished she could just stay in bed with Owen all day.
...
Owen waited as Cristina and his mother brought out his customary birthday cake. He lifted his eight-month-old son in his arms and playfully nuzzled his round belly, causing him to coo with glee. Finally, he heard the familiar off-pitch singing voice of his wife mixed with his mother's raspier one and settled the baby into his lap. But this time, when his mother told him to make a wish, Owen couldn't think of anything. Seeing the beaming faces of his family surrounding him, Owen realized that he had everything he could ever wish for.
