When Scandal kicked off in 2012, Short was one of the very first main characters introduced to the audience. In the series' opening scene, Quinn heads to a bar for what she thinks is a blind date with Harrison, but as she prepares to leave, Harrison tells her that this isn't a date, but a job offer to work with the legendary Olivia Pope. As one of Olivia's "gladiators in suits," Harrison has been by his boss' side for years, and helps her dig into the secret lives of Washington's elite to help clear the names of their clients ... even if they're actually guilty.
For the first several seasons, Harrison is an integral part of Pope & Associates, but in the third season, trouble arrives in the form of Adnan Salif (Nazanin Boniadi), a mysterious, beautiful woman from his past. The two get involved, but Adnan has other plans, forcing Harrison to betray his boss on behalf of her own boss, Maya Pope (Khandi Alexander), Olivia's evil, terrorist mother. After Adnan uses Harrison to get information on Fitz's re-election campaign, Harrison, in turn, figures out that Olivia's equally evil father Rowan (Joe Morton) had the president's son killed — along with Adnan — and is murdered by Rowan and his terrorist organization, B613.
