Hi, I;m Sania, haven't posted here in years. Got swamped by a lot of academic stuff in college, heard that it's the show's last season and started lurking around here to find episode discussions and stuff.
Not to be pedantic, but they weren't dead the whole time. Everything that happened on the Island happened in the show. The last season showed a flash side-ways, purgatory-type deal, where the characters would meet up together after they died (they all died at different times), because the time they spent on the island together was the most important parts of their lives. Man, why do people always get the Lost ending so wrong????? Also, that was a beautiful last episode and I cried like a goddamn baby when everyone started regaining their memories.
Also, dude, you should watch the show, it's very good.
