'Scandal' season 6 episode 7 spoilers: Liv finds out about Papa Pope's sin; Huck to kill Rowan?

Olivia (Kerry Washington) will find out that her own father assassinated the President of the United States. Meanwhile, Huck (Guillermo Diaz) faces the difficult task of murdering Rowan Pope (Joe Morton).

On the next episode of "Scandal" season 6, titled "A Traitor Among Us," Olivia will find out that Papa Pope is directly responsible for killing Francisco Vargas (Ricardo Chavira) and for framing Cyrus Beene (Jeff Perry).

As seen from the episode 7 promo, Olivia is panicking after learning that Rowan assassinated Frankie, and it appears that Olivia will not turn a blind eye.

"After discovering new information about the assassination of Frankie Vargas, Olivia makes a shocking decision and asks Huck to complete one of the most difficult tasks yet," the episode's listing on The Futon Critic reads.

Olivia will place upon Huck the difficult task of killing her own father. Huck will be forced to commit to the task to prove his loyalty to Liv. However, it seems that Olivia has a lot more to learn about the circumstances of Rowan killing Frankie.

During an interview with Variety, Morton explained that his character did it all to keep Olivia safe from the anonymous group of people who want Mellie (Bellamy Young) to be in the White House.

Morton added that if Olivia found out about everything revolving around Frankie's assassination, there would still be unconditional love between them.

"The interesting thing about these two is it's unconditional love, although Olivia has tried to kill him twice, and he has never, ever tried to kill her. So I think if she found out the whole story, they would still be pretty solid," the actor explained.

But even after everything, Morton teases that Mellie sitting at the White House still appears to be uncertain.

"Scandal" season 6 airs every Thursday night at 9 p.m. EDT on ABC.
