Summer Before 7th Year

Regulus Black was pacing.

Very few times in his life had he been at a loss for words but today he knew he wouldn't have the right words for what needed to be said.

He brought his hand up to his face, rubbing at his very square jawline. He knew he needed to get this over with as soon as possible… like tearing a band-aid off. He cursed his family under his breath. Why did he have to do this. He always had to fix his family's problems. No one else in his family had any finesse.

This problem in particular had no good solution. The news he had to bring was about to destroy his family's relationship with some of their closest allies. He was about to change everything for his own family, for the worse, and it was all his awful brother's fault.

Sirius. He ruined everything last night when he walked out. Sure, he'd left plenty of times but he always came back. This time he left for good. It was his 17th birthday and he had been packed for weeks. But Regulus never thought he would actually leave. Especially this weekend.

Regulus sighed. There was simply no way to fix this. He was about to deliver terrible news to his best friend.. the only person he actually cared about in the world. But he couldn't let her just wait and wait. He had to do it. There was no happy- wait. Regulus stopped pacing suddenly. He knew what to do.

Running out of his room, Regulus crossed the hall into his older brother's now deserted room. The only remaining things would be what Sirius hadn't wanted to take with him, so Regulus was sure he'd find what he needed. Yes. There it was. Hanging on the front of the wardrobe like Kreacher had put it there days ago. The tuxedo.

Grabbing the sleek black tuxedo he raced back to his own room and tore his dress robes off. Within minutes he had transformed his appearance and was ready to go. Almost ready. Now that he knew what to do Regulus moved with purpose. He took a moment to rummage through a large ornate box on his own desk. He went through the many compartments in it before he found what he was looking for. Here. Perfect. He put what he had found in a small black pouch and closed the box. He strode downstairs and stepped into the family fireplace and with a puff of powder shouted, "Malfoy Manor!"
