- Hurley is seen reading the manuscript of a book titled ”Bad Twin”, by the fictional author Gary Troup (an anagram for ”purgatory”, by the way).
- ”Bad Twin” is a book set in the LOST universe, and released in the real world in 2006 as a (semi-canonical) tie-in novel written by Laurence Shames. The book includes characters such as Cindy Chandler (the Oceanic stewardess) and members of the Widmore family.
- Sawyer appears to have gotten his hands on the manuscript in Two For The Road, but Jack burns the final pages before he can finish reading it. That might just be the first thing Sawyer does when he finally leaves the island in The End!
- Apparently, ”Bad Twin” did not meet the expectations (or requirements) of the show’s producers and writers. On one of the official LOST podcasts, Damon and Carlton revealed that the fictional writer Gary Troup was the man who got sucked into the jet engine in the Pilot, and joked that he ”got exactly what he deserved”.
- The shots from inside Sawyer’s tent at the beginning and end of the episode show how Sawyer has traded the company of the people he cares about for… a gun – his personal symbol of power.
- When Locke tells Jack that he assumes Jack asks for the combination because he’s afraid Locke might fall off a cliff, Jack responds that ”there are a lot of cliffs on this island”. This could refer to any particular cliff, or Jack’s fall in White Rabbit. It could also be a subtle, sarcastic remark about Locke’s lie in Do No Harm; he told Jack that Boone had fallen off a cliff.
- Of course, Jack will also kick the Man In Black posing as Locke from a cliff in The End.
- At the risk of stating the obvious: Sawyer tells Cassidy that they should ”go find an island somewhere”. Lo and behold, he will!
- Locke tells Jack ”If we arm up, we’re just as likely to shoot each other as we are one of them”. This is what Jack told Kate one season ago (Homecoming). He’s changed a lot in a short period of time!
- Charlie tells Sawyer that Sun can never find out what he did to her. He, too, will change a lot in one season, and actually tell Sun about the con himself in Exposé.
- We learn Bernard is a dentist! This throwaway line comes in handy for Jack in Something Nice Back Home and in the flashsideways scenes from The Candidate.
- Ana-Lucia keeps the running Scott/Steve joke alive when she tells Jack that Scott wants to join the army. And she never even knew Scott (or Steve)!
- Kate tells Sawyer ”We both know you can’t track worth a damn” – a reference to their tracking adventures in Outlaws.
- Locke seems to be looking for more pieces of the Orientation video. Maybe one of them will explain what happened to Sun.
