WARNING! SPOILERS ahead forFBIseason 7, episode 17, “Lineage.“FBIseason 7, episode 17, titled “Lineage,” features a familiar actor as Isobel’s (Alana de Ganza) husband. TheFBIfranchise often features well-known actors in supporting and guest roles, so it’s unsurprising that Isobel’s husband would be well-known to audiences. This character was first mentioned inFBIseason 7as part of an ongoing storyline about Isobel compartmentalizing her home and professional lives. Prior to this story, nothing was known about Isobel’s family.
Although Isobel has been an important part of theFBIcastof characters since season 2, this is the first time that her husband has been on-screen. He appears in scenes at the beginning and end of the episode while Isobel is at home. These scenes are part of a subplot in which Isobel begins to think about whether she wants to retire now that she has been working for the FBI for 20 years.

Cavanagh, who is best known for his role inThe Flash, doesn’t have a lot of screen time in “Lineage.” This is standard forFBI, as the series often has scenes between FBI agents and their families or significant others at the beginning and end of an episode while focusing mainly on the case of the week.
