Promises to the stars

"You see that star, right there?" Sirius asked his little brother in a low voice, "That's Sirius. Even if I'm not here, you can talk to him, and it's like I'm right beside you. I'm never gonna leave your side. We are gonna get out here together. I promise.""On the stars?"Regulus looked up to him with hope in his eyes."On the stars."--------Regulus black promised to never become a deatheater, but what if he still becomes one? What if he decides to use it to his advantage?Sirius Black promised to take Reg woth him and to never leave him behind. What if he left him anyway?He knows Sirius would never forgive him for joining lord Voldemort, and he'll never know Regulus true intentions. Maybe the brothers don't hate each other as much as they say they do, and maybe, just maybe they work together and help each other without even knowing.Or: A story about broken promises and a maybe not as bad Regulus.
