Damian struggled against his restraints. It didn't seem like they were going to give and he hadn't had the foresight to put lockpicks in any place accessible. He hadn't thought he'd need them. His sword lay just out reach, try as he might, like an annoying taunt.
The Red Hood hadn't even needed to use the guns he'd mentioned. It was a decisive blow to Damian's ego and he promised retribution yelling threats (promises to maim for life, missing limbs, the usual) even as the other man ignored him, favoring the recorder.
When Hood said Talia's name, Damian stopped his struggles to give the other man a cutting glare. His family was none of the Hood's business-- then Damian's eyes suddenly narrowed with realization. The only way Hood would know who had the authority to control the League would be... "You know her," he accused.
