There's something reassuring about knowing that the end is near. Not the end of life, but the end of a long trip or the last pages of a book. Television viewers are no different.

The very idea that the upcoming return of 'Lost' -- it premieres Tuesday at 8 p.m. (ET) -- will be the beginning of the end, the build up to the grande finale is both a joyful and bittersweet experience.

To make sure it's more of the former and less of the latter, here's a few keys that will ensure you will savor the return of 'Lost' so that it will be good to the last drop.

On the last episode of Lost, we learned that the Island won't let people die. Well, some people. Michael, for instance. And we can assume the Oceanic Six--Kate, Jack, Hurley, Sun, Sayid, Aaron--experienced the same inability to die as Michael.

But a lot of people have died. Some of them are missed and some of them... not so much. And there will be a lot more deaths over the final two seasons of the series, which returns with a new episode tonight. It seemed like a good time to look back on some of the island's most notorious deaths. And the strange manners in which characters died:

(S02E19) Tonight's episode, S.O.S. (or as I like to call it: Couple's Night), centered around two characters' back stories which we've all been longing to see (or at least Ryan has as he's mentioned it in nearly every single one of our Lost podcasts): Rose and Bernard. Rose and Bernard aren't just an interracial married couple marooned on an island. They would seem to be symbolic of lots of the dichotomies going on in Lost land. One of them was a front-ender and the other a tail-ender, so to a certain degree they are the link that brings the two non-Other "tribes" of the island together. In the opening scene, we also discover that they represent another all-too-common dichotomy of the island: those who want to escape from the island and those who are satisfied to stay and begin building a life on the island. Bernard very vocally notices to Rose that while his end of the plane were fighting to survive, her end was busy building kitchens on the beach, and he claims that they've "given up on being rescued."
