What is Chandler Groff’s biological relationship to JJ Maybank in Outer Banks Season 5?

Chandler Groff is JJ Maybank’s biological father in the Outer Banks storyline continuing into Season 5.

The series character information identifies Chandler Groff as JJ’s biological father. Groff is also described as Wes Genrette’s son-in-law, tying him to the Genrette family and the Season 4 treasure mystery.

This relationship is separate from JJ’s upbringing. Before the revelation about Groff, JJ is known for his troubled home life with Luke, his abusive adoptive father. That distinction explains why “biological father” is the precise answer rather than simply “father.” Groff’s connection to JJ is one of the major facts shaping the revenge-driven premise of Season 5.
