It was difficult to keep to his rage when he saw the pain in Regulus' eyes. Maybe he was weak. Weak for Regulus, if nothing else. His stance relaxed, the tension gradually leaving him, and he leaned their foreheads together. His arms wrapped around Regulus and he sighed, his eyes closing. "I'm sorry you had to see him like that. I would have told you if I'd known you'd seek him out like that. He's spent a decade in Azkaban. I'm afraid that takes a toll on anyone. He wouldn't be the brother you knew anymore."
