Lisbon is the city linked to Chandler Groff at the end of Outer Banks Season 4 and into Season 5. After killing JJ and taking the Blue Crown, Groff prepares to flee there.
The Season 4 finale ends with the Pogues swearing revenge as Groff heads toward Lisbon. That ending establishes a direct connection between the Morocco storyline and the international setting awaiting the final season.
Lisbon is Portugal’s capital and a major Atlantic port, making it a fitting destination for a series built around maritime travel, old maps, and treasure legends. The city’s connection to Groff adds another international location to the show’s final adventure while preserving the series’ focus on movement across coastlines.
