Paul Adelstein is returning to "Scandal" to reprise his role as Leo Bergen, the political consultant. In the Season 3 of this ABC's political drama series, Adelstein had a recurring role. He was the campaign manager of vice president Sally Langston. She was leading the Presidential race but the death of President Fitz's son swung the election in his favour.

According to The Hollywood Reporter (THR), Adelstein is set to appear in an episode that is scheduled to air in November. There are no reports that Kate Burton, who plays Sally, is also returning to reprise her role. Sally may appear in Season 4, as the writers have not yet wrapped-up the character's story-line. In the last season, Sally killed her husband Daniel after she saw photos of him and James in a compromising position. It is Cyrus who helped her to cover-up her crime.

Meanwhile, THR is reporting that Huck's estranged wife, played by Jasika Nicole, is returning in episode 5 of "Scandal" Season 4. In the last season's finale, Huck went to meet his family after Quinn told him where they are living. It was revealed in the premiere episode of the current season that Huck stopped talking to Quinn and did not tell her what happened when he went to meet his family. This week's episode is likely to reveal what actually happened on that day.
