It looks like we'll be getting a flashback episode next week, as Pat Dugan (Luke Wilson) takes a trip down memory lane when Eclipso (Nick E. Tarabay) strikes at his home, forcing each member of his family to confront a dark moment from their past - which could result in the darkest hour of the season.
While Courtney (Brec Bassinger) begins to lose hope, Mike (Trae Romano) must deal with the immense guilt he feels over Icicle's death, and Barbara (Amy Smart) is left to face an unexpected figure from her past.
As revealed earlier today, the next episode will reunite the original Justice Society of America - Starman (Joel McHale), Hourman (Lou Ferrigno Jr.), Wildcat (Brian Stapf), and special guest star The Flash (John Wesley Shipp) - and presumably provide some much-needed backstory on this season's seemingly unbeatable big bad.
