Stargirl changed things up in its first season by killing off not one, but two of Courtney’s classmates. Henry’s storyline and subsequent death were especially sad because he believed that his father could change. Instead, Brainwave proved how merciless a villain he was when he killed off his own son. It was pretty brutal and many wondered whether Henry’s death was a fluke. It wasn’t, and Stargirl creator and showrunner Geoff Johns explained how Henry’s death actually subverted superhero expectations in Season 1.
