Girls star Lena Dunham made one incredible guest appearance on last night's Scandal! Kerry Washington’s Olivia Pope returned to tip-top shape in the episode, titled "It's Good to be Kink," and she jumped right into action after learning of a woman nicknamed Kinky Sue (played by Dunham) who planned to expose the sex secrets of some of Washington D.C.'s powerful elite in a tell-all book that centered on her intimate encounters with them.

Kinky Sue started out as a seemingly easy individual for Olivia to "handle," but quickly proved that she could hold her own when she stopped by Olivia Pope & Associates to demand $3 million in order for her not to publish her book.Olivia, Quinn, and Huck immediately declared war on the United States of Kink and attempted to take her down, but soon discovered that the real truth behind Sue's motivation to release the book was much deeper.

In the end, Olivia convinces Kinky Sue not to release her work—but then things take a turn for the worse, and [SPOILER ALERT!] she meets her end by the hand of a member of the Pope team (you'll have to watch to find out who!). From Kinky Sue's in-your-face wig and sexy Herve Leger bandage dress to her untimely death, Dunham's guest starring role was one for the books.
