The CW has released a preview for “Summer School: Chapter Ten”, the tenth episode of DC’s Stargirl’s second season. This week, Courtney Whitmore/Stargirl (Brec Bassinger) learned not only the awful truth about how to stop Eclipso, but that Pat (Luke Wilson) and her mother Barbara (Amy Smart) had been hiding that information from her and the rest of the team. Now, with the truth revealed and things direr than ever, Courtney and Pat will have to put their differences aside to reach out to someone unexpected: Green Lantern’s daughter, Jennie (Ysa Penarejo). According to the newly-released synopsis, Pat and Courtney discover that Jennie may be able to help stop Eclipso. They just have to find Jennie first. As fans may recall, Jennie left Blue Valley almost as quickly as she showed up earlier this season, continuing her search for her long-lost brother. Jennie did, however, gain powers from the Green Lantern before leaving and it’s likely those powers make her a key part of the plan against Eclipso.
