Selena Quintanilla's resurrection by ISG, coupled with the killing of Yolanda Saldivar by the groups, highlights the mysterious and unexplainable nature of ISG's activities. Selena's optimistic and radiant personality sets her apart from other ISG members, who can be hateful, melancholic, and slightly detached from positive emotions. The members (though not all of them) of ISG often harbor obsessions with violence and a preoccupation with sex or masturbation, but Selena's positive energy is a refreshing contrast in this dark and complex world. Selena's resurrection is considered to be one of the most notable events in the ISG lore.
