Regulus was so bloody happy that Finn and his friends were gone. He liked his room. He liked that he was alone. He liked that he there was pure silence if he wanted to. Of course, he couldn't stay in his room all the time, so he decided to go for a walk when he found Sirius.
"Yes, I did. Finn, he's terrible. He's an hypocritical bastard who lies about his own traditions because he thinks I don't know anything, except I know, because I used to be friendly with someone from his world. Anakin left," Regulus explained.
"How are you and Severus doing? You must have been so busy if you failed to answer the simple question I posed," he said, trying not to get annoyed. After all, he did need Sirius' help and he trusted his brother when it came to charm work. Looking at Sirius, though he realized that something was off. "Would you like to go to my room? Kreacher can get us some tea and biscuits."
