Trivia

 * This comic ignores most of the events of the series after Season 3 and addresses the complaints about the route it has been taking later on, especially by redeeming villains shallowly and pandering to the LGBTQ+ community while butchering those characters' personality traits, by making villains more difficult to redeem and portraying LGBTQ+ themes more naturally.
 * Despite that, some of the events/characters portrayed in the first three seasons could be altered, implying the entire comic is an AU but just set after the corruption and defeat of Jasper.
 * Fusions (aside from Garnet) are used in a more regular basis, especially when it comes to more complex threats.
