At that moment the whole world just stopped. It was him and her. Jack and Gwen. In the middle of the room, while the soothing music floated in the air, they were in their own world gracefully dancing. Nothing else mattered, not Rhys, not Ianto and certainly not aliens. She looked into her dance partners lush blue eyes. They were like pools of serenity, they were beautiful but they seemed to be the oldest part of his body. He looked back in her green eyes full of secret love and passion, and he knew who for. She loved him. But now she was married and he couldn't change that. He wanted her to be happy, he had never liked to see her unhappy. But that was not going to change the love he had for, nothing would change that. He thought maybe Ianto is just a cover, do I really love him? But then that world was interrupted by a voice they both knew to well.
"May I uh?" and then the familiar cough of Ianto. They broke out of their world and Gwen smiled at the welsh man.
"Yes" Gwen exhaled and left Jack taking one last loving glance at him as he watched his almost lover go with her newly wed husband while he danced with Ianto.
