"What are you doing, Snart?!" Barry's eyes filled with horror. A chill rose from his tailbone as fear and fury surged within him. He roared at Reverse-Flash in disbelief, veins bulging across his face. Barry had brought Reverse-Flash here because Reverse-Flash had once been killed by Savitar. His time remnant had been seeking revenge on Savitar ever since, and his hatred ran deep. That was why Barry had been able to suppress the hatred over his mother's murder and cooperate with Reverse-Flash to fight Savitar in order to save Iris.
