During a mission to try and stop a villain called Black Shield and his men, who are intent on retribution to those foreigners who they see as terrorists, Jessica almost accidentally kills a small girl during the fight.
Although she manages to save the town from a deadly pathogen she returns to the JLA satellite plagued with self doubt while Batman and Wonder Woman try to track down the hideout of Black Shield.
Diana sees Jessica is troubled however and counsels her that there is always a risk of collateral risk with what they do as heroes but their job is all about ensuring the least amount of people are harmed.
Wonder Woman manages to then intimidate some of Black Shield’s men they are holding as prisoners into revealing where he is hiding.
Batman, Wonder Woman and Green Lantern arrive at the location but Black Shield proves formidable and even manages to take down Diana.
Green Lantern however focuses her energy on subduing the villain and even manages to simultaneously neutralise several missiles he has launched laden with more pathogen.
As she returns to base she thinks to herself that she still has a long way to go on her journey to become a true hero like Batman and Wonder Woman but she will continue to learn from her mistakes and will never stop trying.
