The Crock family will be quite prominent for Stargirl's upcoming season. For the third season, Neil Hopkins and Joy Osmanski, who play Sportsmaster and Tigress respectively, will be regulars, meaning we'll be seeing a lot more of them in Blue Valley. They'll be making their return this season in the next episode as the surviving members of the ISA. It stands to see how they'll act moving forward, especially since they seem to be currently playing buddies with Pat from the last trailer.
The Vulcan Reporter spotted Javicia Leslie on the set of HBO Max's Titans. While highly unlikely there is a crossover, this could be a joint promotion for HBO Max.
