Love Triangle: Both Frogurt and Hurley have their eyes set on Libby. This is revealed when the former sees the latter holding a DHARMA Cabernet bottle and correctly deduces that Hurley is his love rival. Hurley corrects him saying that he doesn't plan on making a move on Libby, he already has. They are going on a date, even.
Never Trust a Title: Though the episode does focus on Hurley and Frogurt, it would be a stretch to call it an adventure.
Red Herring: Neil "Frogurt" —a secondary character often mentioned by the producers as far back as the second season— who was said to play an important role in the plot. His debut kept being "postponed" until he shows up in Season Five... and is riddled with flaming arrows for being such a whiny little bastard.
Temporary Scrappy: Frogurt, a background character who acts between a Jerkass and a Nice Guy toward Hurley while being The Ghost on the show itself, with the showrunners frequently hyping up his debut and joking that he was the key to all the show's mysteries. When he finally shows up in the series proper in Season 5, he does nothing but complain and is as unhelpful as possible, before being killed out of nowhere by a flaming arrow while whining that the survivors can't get a fire going.
