They had played together as children. They had laughed at their parents, and make faces behind their backs. They had stood up for one another when Mrs. Black had yelled at them.
Now they stood facing each other, wands drawn, and faces set. The years had separated the brothers. They no longer knew who the other one was, and the emotions between them could not have been described.
Regulus shook his head, "You don't understand brother."
"No I don't. Tell me why, Regulus. Tell me why I shouldn't kill you now?" Sirius tried to hold back the tears that threatened to fall.
Regulus gave him a weak smile, "I can't Sirius. I cannot tell you. Just trust me. Trust me as you did when we were younger." He lowered his wand to his side, "Trust me brother."
Sirius watched him warily as Regulus turned on his heel and fled. He dropped his wand to his side as his brother disappeared. He looked at the place where Regulus had stood, "May the gods have mercy on your soul brother and may they have mercy on both brothers of the House of Black." A single hot tear slid down his cheek before he turned and walked away.
