Darius almost replied at that because trust felt stupid, trust was for weak people. But then he closed his mouth. Wasn't he trusting Charlus? Wasn't he trusting her, right now, not to kill him on the spot? Maybe. Possibly. He didn't really want to think about it.
His tongue clicked and his expression twisted in annoyance when she mentioned her brother. He still did not completely trust him, still disliked him for so many reasons, but he put aside any ill will towards the older Higgs. At least Aidan had warned his sister, though he had then proceeded to abandon her on her own—hadn't he? Darius was getting annoyed and it was not the moment for that, so he focused on her question instead. “What would I do with the mask? It has no tactical advantage. Death Eaters would know who I am anyway . At least this way, the others are not going to kill me when I turn a corner,” he explained, failing to make anything clear. “I.. remember,” he said, looking down. He didn't like to feel guilty. It was a feeling he rarely experienced and fully loathed. “Well. It turns out that I prefer be loyal to my brother's blood than to my father's.” And saying it like that made it a little more easy to swallow. He was still proud of his choice. “And.. I'm—.”
Darius paused. He looked at her, at her eyes, into them. He held his head high, his shoulders straight, and took a deep breath. “I'm sorry,” he said, and while he had thought this would be difficult, it turned out it was not. “I'm sorry for having said all of those things about you. They are not true. They never were.” He twitched his nose. “Well. You are a blood traitor, or anyway.. a traitor to the cause. But turns out, I understand choosing one's brother over it.”
