The CW has released a preview for “Summer School: Chapter Nine”, the ninth episode of DC’s Stargirl’s second season. The episode is set to air on Tuesday, October 5th. While much has been made of this episode being the big “crossover” of sorts that will see John Wesley Shipp appear as Jay Garrick, the original The Flash of the Justice Society of America in a pivotal flashback, the preview gives a bit more insight into what’s going on in the present. From the looks of things, it’s about to get very chilly - and scary - at the Whitmore/Dugan house. In the preview, the storm that’s been brewing in Blue Valley only gets worse while both Barbara (Amy Smart) and Mike (Trae Romano) seem to be the next targets of Eclipso and as things get colder, the appearance of Cameron Mahkent (Hunter Sansone) with a sinister warning that everyone in the house is going to die is especially terrifying. You can check out the preview and the official episode synopsis below.
