Corrected entry: In Charlie's flashbacks aboard the aeroplane, we see he goes into first class to snort the heroin. As the turbulence hits, he leaves and nearly gets hit by the trolley, before buckling himself in - still in first class. Therefore when the plane goes down, Charlie should've been in the first class section of the plane and consequently shouldn't be alive and on the beach with the rest of the survivors.
Corrected entry: During the second half of the Season 1 Finale "Exodus", Hurley is rushing to the airport to make his flight. When Hurley's car suddenly breaks down on the way to the airport, there is a close-up of the dashboard, and in clear green numbers we see "42KM 23C 15KPH speed". The dashboard display then quickly switches to flash the green numbers "42 KM 8/4KPH (8 changes into 4). When Hurley makes it to his gate it is number 23.
Correction: Again, the reoccurrence of these numbers are fairly obvious plot points. Listing every time these numbers appear in the show is unnecessary. The fact that at least one these numbers will appear in almost every episode indicates the relevance of these numbers to the island. No need to point out every occurrence.
Corrected entry: Whenever Charlie is seen snorting drugs, Dominic Monaghan is actually snorting brown sugar.
Correction: To acquire realism, actors snort and inject themselves with non-toxic stuff. It should not be considered trivia if actors do something to better their perfomance. Specially if it's done often.
Correction: This scene is not shown in real time (i.e. continuous). If you look carefully, just before he finds a seat to buckle himself into, behind him is the divider he passed on the way to first class. Although it does not make sense, he must have crawled all the way back to the middle section of the plane. If he sat immediately in first class you would have seen the glass wall behind him, but you do not.
