Which Season 5 character is identified as JJ’s biological father in Outer Banks?

Chandler Groff is identified as JJ’s biological father in Outer Banks.

The series identifies Chandler Groff as Wes Genrette’s son-in-law and JJ’s biological father. J. Anthony Crane portrays Groff, who became a recurring character in Season 4 and a series regular in Season 5.

This relationship is different from JJ’s upbringing. Luke is the man who raised JJ, but the story distinguishes him from JJ’s biological father. That family distinction becomes an important part of JJ’s Season 4 storyline.

Groff’s connection to JJ also links him to the final season’s central conflict. After the Season 4 finale, the Pogues are left dealing with Groff and the consequences of his actions while trying to recover their future.
