(S05E03) "Because... he's one of my people." - Locke

I really need to get in the habit of taping my mouth shut while watching Lost because my jaw is always on the floor by the end of every episode. Time-traveling has added an entirely new dimension (literally) to the story-telling techniques of this show and the first three hours of this season have been some of Lost's best. The flash-backs always lacked a certain amount of tension because they already happened. On the flip side of the same coin, the same can be said about the flash-forwards because you know they're going to happen. But time-traveling has created this new ripple where nothing has permanence anymore, whether it happened, is happening, or will happen. This is mesmerizing stuff to watch unfold because everything becomes new the second Faraday, Locke, and Co. make a new jump. They may not be altering the ultimate outcome, but they are altering the moment.

(S05E01) "You're gonna have to die, John." - Richard Alpert

Time travel! The future is now! later! here! gone! beginning! ending! OK, I give up. Lost is back and the future is... well, we don't know what the future is. Or the past. Or the present. All we know is what they were, because now they're just one big time travelin' mess.

As with seasons past of Lost, the fifth chapter of TV's favorite mindf*ck opens by presenting an entirely new storytelling technique - one that demands equal parts patience, attention, and imagination. More than anything, it's a test for true fans because the casual Lost viewer (do they exist?) probably had a hard time moving from A to Z (worst metaphor ever - I know) in tonight's season premiere. That being said, this whole hour gave me my own bloody nose.

Not the actors and actresses that will be playing these parts, but the characters themselves. If it's true that the outside world will now become a plot point in the show (and after seeing the two Arctic station guys and Penelope on the phone at the end of the season finale, it looks like it will be), new characters on Lost will include:

• Female, 30s, with leadership qualities
• Female, early 20s, very attractive
• Male, Latino, early 20s, handsome, mysterious quality

So who do you want to see in these roles?
