The Boys season 3 includes a reference to Supernatural, with Starlight echoing a line from the show to Maeve. The Boys creator Eric Kripke also created Supernatural, and there have been multiple Easter eggs between the two shows. Maeve's season 3 finale sacrifice is foreshadowed by Starlight's line, which highlights Maeve's self-hatred and lack of care for herself. However, her sacrifice leads to a new life away from Homelander and Vought, showing Maeve beginning to forgive herself. The emotional conclusion to Maeve's arc correlates with Starlight's Supernatural-inspired message.
