There are several mysteries Outer Banks still needs to answer, including what happened to Sarah Cameron's (Madelyn Cline) mom. The hit Netflix series has continued to explore more of its main characters' families as it has progressed. Outer Banks season 2 included the big reveal that Pope (Jonathan Daviss) is a descendant of Denmark Tanny, making him Figure Eight royalty in a sense. Meanwhile, John B.'s (Chase Stokes) dad became a large part of Outer Banks season 3.
