A/N: I'm in the mood to write something depressing.

Watch

Sirius watched as she slowly fell for his best mate.

He watched as, with time, her eyes came to hold more trust for the bespectacled boy, trust and understanding.

He watched as she grew closer to the other, the one that should have been him.

He watched as she whispered, believing her and the young man she had once hated were alone, those three words. The three words that would tear his heart so. The three words that would change all of their lives forever.

Sirius Black only ever loved one girl, but it was the one he could never have. Because, as much as he had loved Lily from the start, he owed James. James, who had become his brother when his biological brother was good as lost. James, who had taken him in when no one else would. James. James.

Sirius remembered thinking, once, that perhaps she felt the same way. That perhaps she loved him, too. Wishful thinking. Lily Evans would never love him. She was too good for him, too wonderful. Too . . . perfect.

He would never have her. She was not his to have. She belonged to someone else. He accepted that.

But he had always hoped that perhaps, even if she never truly fell for him, he would get a taste of her. He would get to know what it was like to have those sensual lips on his, that gorgeous body pressed against his own. He never wanted to wonder what it would be like to run a hand through her fiery mane, or feel her shiver after whispering into her delicate ear.

But he would be forced to. He would be forced to wonder for all of eternity, while James was allowed to do those things every day. Every single day.

Was it fair? Was it fair that Snivellus, of all people, had gotten a bigger piece of her than he ever had? Was it fair that James, after putting the girl through years of torment, was the one she would end up with?

No. At least not in Sirius' eyes.

But it didn't matter.

Sirius would still watch them have children together, and know what they had to have done to have those children.

He would watch them grow old together, as he grew old, too.

He would watch them be happy together, pretending to be happy himself.

And the worst part of all was that all he could do --- just like all he had ever done --- was watch.

A/N: So what do you think? Not in the best of moods at the moment. I've always thought sad, Sirius/Lily fics were beautiful, and so here is my attempt at one. PLEASE REVIEW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
