'Scandal': Olivia Shocked To Find Out Who The Mole Is (VIDEO)

After a season of guessing on the part of both the audience and the cast, "Scandal" was finally ready to reveal the identity of the mole. The reveal caused Olivia to drop her jaw, but we suspect she wasn't the only one who's mouth was agape at that moment.

“Billy Chambers," Harrison told her. "Billy Chambers is the mole.”

TVLine thought it was a pretty big reveal, especially considering that Billy Chambers -- who was Sally Langston's chief of staff -- had been assumed dead. And Billy's not working alone.

A scene showed Billy in a limo saying, “Now we can start having some fun.” An expanded shot revealed that he was talking to David Rosen.

“And not only is Billy Chambers the mole -- he's in cahoots with David Rosen!" marveled Entertainment Weekly. "Suddenly, it all starts to make sense. The two guys who had their lives ruined at the hands of the Grant administration are working together. It's revenge, plain and simple."

See how Olivia and her team respond to this news on next week's big "Scandal" finale, Thursday at 10 p.m. ET on ABC.
