"There are thirteen original members, but they have ... acquired four more in the past few years," he said calmly. "They started when they- we got out of Hogwarts in 1979, but it was hard to distinguish between who was doing what for what reason and the Dark Lord didn't care if people were killed. Not all of them started with murder either. Unlike what the Ministry says, not all Dark Arts involves killing people, or even hurting them. Some members are more intellectual while some are more practical, you can say."
Regulus smiled. "That's because I'm not an idiot. I don't want protective custody. If I wanted to live like a prisoner, I could have stayed where I was. No, I'm tired of hiding and people thinking I'm dead. I want to go home... if Sirius hasn't destroyed the house, that is. I want people to know just what I've done. It's time and if Dumbledore has a problem with that, I can share a lot more that he wants me to share, considering that he got the information about the Dark Lord from me," he added coldly.
The smile returned like the warm sun after a gust of wind. "I can also protect myself. I wouldn't be talking to you if I thought that I couldn't. There is one person who would make it personal and could endanger my life and that's one name I'm willing to give you, but he won't give you any more and the moment you arrest him, the others will know that I've talked and will disappear." He sat down again. "Please understand that this isn't a threat or a dare, but I will go public. I'm done hiding and your opinion on the matter won't change my mind. I am willing to help the aurors in the process if you want. If you don't, I can protect myself. I survived the Dark Lord, I can survive a few wannabes. But as a show of good faith, I'll give you a name: Byron Rosier."
