Did You Know?


Desmond's condition following the mishap during the helicopter flight to the boat is very similar to that of Billy Pilgrim, the main character of the novel 'Slaughterhouse-Five', who becomes "unstuck in time" and has multiple experiences in which his consciousness jumps backwards and forwards to different points within his own lifespan.

When Desmond is speaking with Mr. Widmore in the restroom, Widmore washes his hands by grabbing a towel from a tray to the right of the sink. He leaves the water running and leaves the restroom. Desmond then flashes back to the boat. When Desmond flashes back to the restroom it looks like the tray is to the left of the sink that was left on by Mr. Widmore in the previous scene.

In fact the shot has simply widened showing towels next to each sink in the restroom. The towel used by Mr Widmore, as well as the tray he got it from, is still to the right of the sink as he left it. See more »


Desmond Hume: Set your device to... 2.342 and make sure it oscillates at 11.
Daniel Faraday: OK, now, you... You're gonna tell me who told you those numbers.
Desmond Hume: You did.
Daniel Faraday: Wait a second. This is ridiculous.
Desmond Hume: I know about Eloise.

Best Episode this Season
8 March 2008 | by (United States) – See all my reviews

This is an episode that keeps your attention the whole way through. I can say, for me, without a doubt this is the best episode this year and probably the best episode of the entire series. I recorded it and will keep and watch it over and over. This episode sheds light on some of the questions I have had since the beginning of the season. It will be interesting to see where the writers go from here. Will they go further down the rabbit hole? Will they skew off into another direction? I can't wait to watch the next few episodes. I'm as excited as ever to be a Lost fan.I wont give away any details. Just pay attention and enjoy the show.

Thumbs up! Way up!

10/10 for sure
