In the second that Prim grabbed at his wrist, Ryuu extinguished the elemental blaze, the fire dissipating with a small fwoosh. Despite his threats, he had no desire to harm anyone, especially not Prim. Just as quickly as his flame had gone, however, an invisible flame of irritation perked its bright head inside his mind.
Like always, Prim stood in the way of his trying to help her, tried to get him to leave, and, while that might have worked in the past, he was not going to let it work this time. He was not going to stand by and watch his friend be abused by this vulgar excuse for nobility.
Taking Rusger—who did not squirm due to his disgruntlement—Ryuu ignored Prim, not looking her in the eye and instead maintaining his eye contact with her uncle. "I'm sorry, Prim, but you're wrong," he said, "this is not a 'private matter.' Your uncle has insulted my family, and our character and virtue—which," he added, "I will not allow to continue."
He stepped past Prim, standing right before her uncle, then gave a low bow, eyes still locked onto the other's. "As I stated before, we'll now be leaving. Prim." He turned to his friend, nodding at her and then nodding at the door. Rusger glared around Ryuu's arms at Engilram, his senses keeping Ryuu alert to the possibility of an attack from behind.
