in accompanying him came to an end at that point, and that they would not see much of each other after that mission. Cast and characters Dan Vasser (played by Kevin McKidd) is a reporter for the fictional newspaper the San Francisco Register. Dan is the main protagonist of the series, who finds himself jumping through time, unable to stop or control the jumps. He has a son, Zack, with his wife of 7 years, Katie — his brother's ex-girlfriend. Dan was previously engaged to Livia Beale before her disappearance and supposed death in a plane crash. Dan is a recovered gambling addict. Katie Vasser (played by Gretchen Egolf) is Dan's wife and mother of their son Zack. Until recently, she was the only one in the present who knew about her husband's time-traveling. Katie was the long-time girlfriend of Dan's brother Jack. Since their break-up nine years ago, the two have remained somewhat distant; partly because Katie ended up getting pregnant by Dan and they married soon after. Before marrying Dan, Katie was a television reporter. In response to cutbacks at the Register, and Dan's traveling, Katie returns to television to ensure a stable income for the family. Olivia "Livia" Beale (played by Moon Bloodgood) is Dan's ex-fiancée who was presumed dead after a plane crash nearly ten years before the start of the series.

After not being able to jump home for an uncertain number of years, she was stuck in Dan's present and adapted to life there, where she began a legal career and fell in love with Dan, only to finally jump back home while on the plane before it crashed. In "Blowback" and in the final episode, "Perfidia", she and Dan speculated that Dan was the target of her extended jump, and that her mission was to get Dan and Katie together (which was arguably a result of her supposed death). For unknown reasons, she now jumps to the same times that Dan visits, and offers him advice and assistance in his missions. Jack Vasser (played by Reed Diamond) is Dan's brother. Jack, a police detective, is dating Dr. Theresa Sanchez (Lisa Sheridan), but also has feelings for Katie (his ex). Jack forms a number of misconceptions about Dan's disappearances and apparent irresponsibility, refusing to believe his brother
