A small 'eep' escaped her as Spoiler swirled around to get a look at the newcomer. She'd been too busy examining her arm to notice Dinah. Probably not a good idea considering she lived in the most crime-filled city in the whole of America. Spoiler straightened immediately and tried to shrug of her cut, no need to look like a wussy in front of the Black Canary after all. She'd most probably have had much much worse than a flesh wound like this, Spoiler thought to herself.
"It'll heal. No biggie. And I swear I'm not evil and have no intention to be," she announced, "Just FYI, you know."
Taking out three batcuffs from her utility belt, Spoiler sat primly on the unconscious guy and cuffed him.
