DISCLAIMER: Harry Potter does not in any way, shape, or form belong to me. I merely steal J.K. Rowling's world and twist it to suit my needs (heh heh).
Part III Final Conflict
Sirius sealed the love letter he had just finished writing and gave it to his eagle owl, Hermes. The snowy white owl flew out of the bedroom, leaving Sirius alone with his thoughts of his beloved Kalila. She was two years ahead of him and had just graduated Hogwarts.
A shriek sounded from downstairs. 'Mother probably just found out about Regulus' fight at school,' Sirius thought with a smirk. Regulus had gotten into a fight with Lily Evans on the train. Sirius had quietly hexed him while hiding so no one could see that it was him protecting Lily. Not only was Lily James' love, admittedly unrequited, but Sirius had felt especially protective of Lily because of what his parents had done to Petunia.
Sirius' door flew open. He looked over to see his mother standing in the doorway with a slightly torn piece of parchment in her hands. Her half crazed eyes were bulging slightly and her face was bright red.
"Who the hell is Kalila?" she screamed.
"You read my mail!" Sirius yelled in shock.
"Answer the question! Do I need to get the truth serum?"
"Who do you think I would write a love letter to? My girlfriend, of course!"
"How could you? She isn't…pure."
"Depends on your point of view. Kalila happens to be 100 Egyptian Mudblood."
Sirius' mother began to moan and clasped her head with her hands. Silent teaks streaked her face leaving tiny trails of pain.
"Regulus would never do this! Regulus wouldn't break his poor mother's heart. Regulus-"
At that moment Regulus walked by and, upon hearing his name, rushed over.
"What's wrong, Mama?" Regulus asked and hugged his mother. She just sniffled as Sirius rolled his eyes.
"Mama, let's get a calming draught." Regulus led his mother away as Sirius closed the door. He knew it was only a matter of time before his father came in. He threw his belongings into a large trunk and called several house elves to carry it down for him. They couldn't refuse a direct order, no matter how much they wished they could.
He walked behind them as they slowly carried the heavy trunk down the grand staircase. Once outside, he told them to put it down and not to tell any one what he had done until morning. After they had gone, he stuck out his wand arm.
The Knight Bus barreled recklessly down the quaint street. Sirius pulled his trunk onto the bus and said with one final look, "Adios, bitch."
