Black Brothers
"Sirius?" Regulus started to reach out. Sirius flinched back like one touch from regulus might kill him. Regulus' arm stayed out, sleeve pulled up, and bearing the mark of the dark Lord. Sirius looked from Regulus' hand to his face.
"Why? Why would you do this?" There was something behind his eyes. It wasn't quite betrayal. It seemed to be a mixture of betrayal, hurt and pity.
"I had to, there was no choice Sirius. I'm still the same person. I'm still your little brother." Regulus had started to sound desperate. Hoping Sirius would understand.
"No, Reggie. You look like yourself, you may act like yourself but you're somebody else only it's not on the surface. Deep Inside of you, you've changed. It will never be the same again." Sirius' gaze started to harden.
Regulus could see as the mask both of them had created started to slip over sirius' face. Regulus might have believed it was real if a tear hadn't fallen over Sirius' cold eyes.
Regulus was overcome with emotions. His brother didn't trust him anymore because of the mark that was forced on him. Sirius stared for a moment longer. Neither of them dared to speak a word and break the silence.
Sirius started to leave, and regulus just watched after him. Regulus backed up into the wall in the abandoned hallway and sunk down.
He pulled his legs into his chest and leaned his head forward until he hit his knees. Regulus didn't cry often. It was really a nasty response to the household he was born in, but this was the exception.
Regulus let a sob rip through him as he thought about his brother.
