Is Juliet dead?

There is no evidence that Juliet is dead. After all, no one died when the Swan station left a 30 foot crater in the ground. On the contrary, we found Des running around naked. Perhaps Juliet will show up next season naked as well. Added to that, the writers told us one of our loved characters will die. Ummm. It could be argued that's Locke.

There is no evidence that the bomb actually went off. Perhaps the electro magnetic field just finally burst, as in the Swan Incident. On the contrary, the bomb was rigged to blow up on impact, but it didn't. That would mirror why Walt's gun wouldn't work, and if it's true, means even Juliet's pounding didn't set it off.

There is no evidence the Locke, Des, Ecko Swan incident pushed anyone into the future. Although they did take a day to be found, and who knows what happened then; they could easily have flashed somewhere and eventually returned. After all Des was naked:) So we have too few facts to predict where the present Swan situation will take the Losties.

Until Season 6x1 comes along, I'm not sure what we saw in the Finale.

Finally, I was non plussed by the Darlton's use in the Finale of romance to drive actions of huge significance. While we are all aware that love plays a significant role in everyone's life, I find it unreasonable and out of character that either Juliet or Jack would make incredible decisions affecting everyone on the island because of it.
