The Starz pirate show is almost coming to an end, after the last "Black Sails" Season 4 episode. In Episode 8, Flint and Silver's partnership suffered when the former stole the treasure. "Black Sails" Season 4 Episode 9 spoilers, meanwhile, reveal that Silver will start hunting his old friend on Skeleton Island.
In the last episode of "Black Sails," viewers saw Flint admitting to himself that he might not be able to fulfill his dream of leading a free Nassau. According to Den of Geek's Episode 8 review, Henry Avery's history looming in the background will bring everything full circle. "Black Sails" Season 4 Episode 9 spoilers indicate that Flint will be doomed.
Avery is a legendary figure in pirate lore and the show needed to express his importance to Flint's eventual fate. It's not surprising that it was Flint who had Avery's journals, after all. Flint (Toby Stephens) and Silver's (Luke Arnold) friendship was one of the foundations of the show. Recent "Black Sails" Season 4 Episode 9 spoilers indicate that their fall-out will lead quickly to events in the novel "Treasure Island" by Robert Louis Stevenson.
In Episode 8, Flint lied to Silver and made off with the chest. Now, Silver will hunt him down on Skeleton Island, as revealed by "Black Sails" Season 4 Episode 9 spoilers. Jack (Toby Schmitz) meanwhile, will be heading to the island with Avery's men. Things are coming together for one last treasure hunt before the show ends.
According to CarterMatt, "Black Sails" Season 4 Episode 9 spoilers reveal Silver and his men hunting for Flint, Madi receiving a mysterious offer, and Bill finally choosing his side. Flint's death occurs around a few years before the events of "Treasure Island". According to the characters, Captain Flint had died due to too much rum, but had given his map to Billy Bones before his death.
"Black Sails" Season 4 Episode 9 spoilers hint that the show's more serious take on piracy will also bring viewers a darker and more heartbreaking end to Flint's life. The actors and producers of the show have hinted previously that the show will end well into the events of "Treasure Island", which means that viewers will eventually see Flint's death on screen, after his fallout with Silver.
