You're angry at yourself. Power weak little wannabe hero girl unable to save her new partner and friend." He taunted her calmly. It was kind of a dick move.

Before Bart could finish Nathaniel punched him. He then kicked Rose. "Leave. I don't need you." Kid Flash said coldly. "What are..." Rose stopped. "Just take Red and GO!" He shouted before started to attack them. He wwas pushing them back trying not to hurt them, but still. He couldn't say no to Deathstroke. Not right now anyway. 

"It looks like my grandson is doing his job fairly well." Deathstroke said calmly. "Get her out of my sight Red Devil." He said before turning away from Red Huntress.
