Grey’s Anatomy is welcoming back a familiar face in the November 14 episode, and he’s walking right into Callie Torres’s arms.

A few sneak peek photos courtesy of The Hollywood Reporter show Callie’s father, Carlos (Hector Elizondo), embracing and consoling her sweetly, sharing an adorable father-daughter moment over some wine. (Notably, there is only one glass, so perhaps he surprised her while she was drinking solo.)

However, Carlos may not be returning just to help his daughter through her rough separation from cheating wife, Arizona — he comes with an “interesting secret” in tow.

While we initially thought that secret could be about a potential divorce from his wife, he is clearly wearing his wedding ring in the photos, so that’s ruled out. “Interesting” doesn’t sound like someone might be sick or in danger, so maybe Callie will be welcoming a sister or something else shocking.

Either way, we hope that the Callie-centric episode includes confrontation with Arizona and/or Carlos imparting advice on forgiveness for his daughter. Mostly, though, it should be about helping Callie through a rough time. In addition to her relationship issues, she’s sitting in court for a malpractice suit, and in the photos, both she and her lawyers look worried and shocked. Uh-oh.

Could this be because of Callie’s crazy work ethic? Recently, Sara Ramirez told THR that "Callie is going to throw herself into her work and distract herself with other colleagues in terms of what they're up to in their lives and Arizona is finding her way on her own and what ever way she can.” We know that Arizona has also found her way in bed with intern Leah, while Callie is still sleeping solo, but that could change at any time.

What do you think Callie’s father’s secret is? Sound off below, and catch Grey’s Anatomy on Thursdays at 9 p.m. ET on ABC.
