Mellie (Bellamy Young) has had enough of Fitz (Tony Goldwyn) and she’s finally ready to tell the world why. After an explosive episode last week, “Scandal” returns this Thursday to the ongoing investigation into the mole and Mellie’s threat to expose the president’s cheating ways.

Last week, fans witnessed as Mellie finally walked out on Fitz taking their small son with her to the house across the street from the White House. However, she didn’t leave before giving him an ultimatum: leave Olivia (Kerry Washington) or be prepared for Mellie to expose his cheating with the entire world, risking his chance at a re-election. The ultimatum “forces Cyrus (Jeff Perry) into the role of ‘fixer’,” ABC teases.

ABC adds, “The team continue their investigation into the mole and make a shocking discovery in the process. Meanwhile Fitz orders Jake (Scott Foley) to continue to protect Olivia, who is still much in danger.” Will the truth finally come out about everything Jake is actually involved in?

There are just a few episodes left until the season two finale of ‘Scandal,’ which will air on May 16 and will be entitled “White Hat’s Back.” What we can spill is that fans will get a chance to see ‘Arrow’ actor John Barrowman make an appearance on the penultimate episode of the season on May 9. No word yet on what role Barrowman will take. Fans will have to wait and see.

'Scandal' S2E20, "A Woman Scorned," airs on Thursday, May 2 at 10 p.m. EST.
