Last season, Private Practice viewers watched as Addison's brother Archer suffered through a life-threatening disease.
It like like this was just an initial look into the Montgomery family, as a series rep tells People that fans will soon learn a lot more about her privileged background.
In a November episode aptly titled "Sins of the Father," Barry Bostwick will guest star as The Captain, as Addison's dad drops in to Oceanside Wellness Center.
Daughter and father “have bad blood between them,” the show insider said. “It’s a tense relationship.”
Bostwick is best known for his former role as the Mayor on Spin City. In 2009, he appeared on Nip/Tuck, Ghost Whisperer and Supernatural.
UPDATE: This role has been changed. Stephen Collins will now portray Addison's father.
