I posted in the LLL thread and N.U.M.B.E.R.S., and now I want to speculate.

I've noticed the lostaways use "3 reasons" for the things they do.

Hurley while telling Locke why he shouldn't have lit the fuse. 1- I was running towards you 2- I was waving my arms 3- I was telling you not to.
Hurley gave 3 reasons not to go into the Dark Territory
Danielle tells them they can run, hide or die.
Locke gives 3 reasons to wait. For morning, to see if the other show, or if the brave rafters bring help. But me, I'm tired of waiting. MORE?

When Jack was calling it a night, why did Kate interrupt her convo with Locke? What was her goal?

Desmond was just waking up, and it was nighttime? Does he leave the Hatch at night?

Desmond says he was almost a doctor. Jack says "small world" Understatement!!

Did Jack (partly) marry Sarah because she missed her first wedding with Kevin?

Kevin mentions Sarah going for a dress fitting. Could it be a Carlisle store?

Does the picture in Jack's office look familiar to anyone?

Just before Jack operated on Sarah, did she "let him off the hook?"

Desmond said "self flagellation" Seems important??

Desmond, "See you in another life"
Locke's dad, "See you on the other side"
Nadia, "See you in the next life"

What is a Tour de Stad? Is that real? It reminds me of Boone's Theresa falls up the stairs, Theresa falls down the stairs.

Jack's comment, "I'm intense", seemed important??

Sarahs comment, "You're yanking my chain, right?", seemed important?
