This woman must have been a neighbor if she was holding a grudge over his music. Trenton's eyes tightened with an increasing glower of impatience. "In case you haven't noticed, I don't exactly have functioning arms right now, I had nothing to do with the music being that loud!" Flustered, he slumped in the chair, which seemed to be the only movement that his restraints allowed for.
Her remaining concerns sank in on him in the silence that followed. He wasn't overly worried that the knife man was going to return any time soon. The stranger'd had his chance to slit Trenton's throat or slice him into a dozen pieces of various shapes and sizes. But he hadn't. He'd left with a warning.
As for why Trenton was so lively and vigorous with snappy comebacks when he should have been in some kind of shock, he closed his eyes with the explanation. "Must be.. adrenaline.." He even went a little limp then, for special effects. Hanging his dark crown for the sympathy vote.
