Maybe Sirius was happy for James and Lily... or maybe he wasn't. My take on the second, just cause I wanted to write a James/Lily one-shot and cause I love the song I used for this and had been trying to do a songfic with it for ages.
Thankies Maderaux Toxic- I looked back at that line and it is rather confusing. It's been changed now.
Fake Smile
"Padfoot... come on, Padfoot, it's not like-"
Sirius slammed the phone down and threw himself onto his bed.
Prongs is getting married.
The phone rang. Sirius ignored it.
It rang again. Sirius picked it up. "What!"
"Sirius... why are you so mad at me?"
Sirius laughed darkly. "Why? My best friend is getting married. I'm losing you. We all are."
"Padfoot... you won't... nothing's going to change."
"Yeah right." Sirius hung up again, unplugging the phone as he did so.
Sirius remembered all the pranks he, James, Remus, and Peter had played in their seven years at Hogwarts and smiled.
Then he remembered the day Lily had finally said yes when James had asked her out, and how happy James had been. He remembered faking a smile, saying, "That's great" and hating Lily.
Sirius buried his face in a pillow. The day had been going fine, and now his world was falling apart.
Prongs is getting married.
"Padfoot?"
Sirius looked up. James was standing over him, looking worried. "You okay?" Sirius just looked at him. "Okay, stupid question." James sat down beside him.
"I just... I can't believe... I never thought you would..." Sirius couldn't finish his sentence.
"You've known I love her," said James softly.
"Just... I just want to be alone."
James nodded and Disapparated.
Next thing I know, he'll be asking me to be best man. Sirius laughed. That'll never happen.
Harry flipped through the album to his favorite picture. It was a picture from his parents' wedding. James was in the middle, one arm around Lily's waist and the other around the best man, Sirius's, shoulders. They were all smiling.
And anybody who didn't know wouldn't have been able to tell... one smile was fake.
