Abigail Grayson is a character featured on Conspire, a WKTT show originally made available in the downloadable version of The Ballad of Gay Tony for Grand Theft Auto IV, and later in the Episodes from Liberty City editions of The Lost and Damned and The Ballad of Gay Tony.
Abigail is primarily featured as a guest for the show, discussing Connect the Dots, a conspiracy handbook and survivalist's guide written by Abigail and targeted for children. In the interview, she claims that she shifted focus of pushing her ideals to children because adults no longer listen to her due to her overly paranoid worldview.
Over the course of the interview, Abigail becomes increasingly delusional, ending with her sudden PMS-induced outburst when it is revealed that she is unable to talk further about her book as the show is ending, inevitably revealing the identity of Conspire host John Smith and her husband-wife relationship with him.
Abigail is voiced by Jen Cohn.
