Olivia Pope Must Tackle Tough New Case Involving Sex Secrets On 'Scandal'

In the episode It's Good to Be Kink, the Girls star plays the role of Sue Thomas, a blogger who's threatening to expose sex secrets about some of D.C.'s high-powered politicians.

Thomas has written a tell all book where she recalls all of her sexual encounters with these men and shockingly Abby learns that her boyfriend Leo, is one of the men being compromised.

Will Huck Turn On Olivia Pope During New 'Scandal' Episode?

Afraid that her career will be ruined in the book is published, Abby pays a visit to Olivia Pope in hopes that her BFF can handle the situation and prevent the book from coming out.

At first, Sue refuses to go down without a fight and she requests $3 million in exchange for the book and her silence.

Another shocker occurs when Abby realizes that David Rosen is among the group of men that Sue has slept with. Rosen is worried that if he's exploited, his career will be ruined which also worries Huck because the ex B613 member is in need of immunity after exposing top government secrets during last week's episode.

Liv comes up with a plan to help Sue get another job and get back at the man who sexually abused her in the past if she agrees not to go through with her book deal.

Sue agrees but sadly it's too late because Huck decides to kill her anyway because he needs to ensure that Rosen is never fired. 

Scandal airs every Thursday night at 9 p.m. on ABC. Viewers can watch a sneak peek of the new episode Put A Ring on It in the video below.
