When "Scandal" comes back for its fifth season, fans will notice that Marcus Walker will be shown more often than not, and that is because, as reported by TVLine, actor Cornelius Smith Jr. has been promoted to series regular. 

Smith Jr.'s Marcus Walker was only seen in two episodes in the previous season, but those quick appearances made such an impact that he has been included in the next season's main cast. This has led fans to speculate that the character is going to shake things up even further in the fifth season, following the already explosive nature of the season 4 finale. 

Season 5 will also address some of the hanging issues from that finale. Case in point, actress Bellamy Young recently sat down for an interview with Hollywood Life and explained that her character, First Lady Melody "Mellie" Grant, would fight back against her husband President Fitz (Tony Goldwyn) after the latter threw her out of the White House. 

During the season 4 finale, the President learned that Mellie had something with Vice President Andrew Nichols (Jon Tenney). Rage ensued and Mellie was kicked out, but according to Young, she won't take that kind of treatment and is determined to fight back, even if she is going against the President of the United States.

"I can't imagine her saying, 'well I accept,'" Young told the news outlet. "I hope ultimately that Mellie is president and Fitz is by her side and he loves her so much again and they've weathered that Olivia storm, and now they're together and it's happiness."

However, fans of the series know that the two might not get that happy ending just yet as Fitz did end up sharing an intimate moment with Olivia Pope (Kerry Washington) during the season 4 finale. Only time can tell whether Mellie and Fitz still have a future together, romantically or politically.

"Scandal" season 5 premieres this Sept. 24.
