I believe those are Jack's. Scientists say that the color of our eyes is associated to our skills: http://leerlenguajecorporal.blogspot.com

Lost season 5 was great:D But open end.. it is so exciting i can't wait till 2010.. i'm form germany, so i have to wait till 2011 maybe-.- They always show the season an half year or a year after you saw it in america.. thats idiotic -> so i show it like this season with german subtible^.^ I'm hooked :p

It's Jack.... can't wait until 2010...

Perhaps my pixels aren't working on my screen cause those eyes aren't showing up blue at all! I'm voting those are Jacks!

I immediately thought it was Jack's as well, and my next thought was that the "reset" will find everyone back on the island at Day One -- but with only some of them retaining their memories of what happened.

My immediate thought when I saw that eye was that it was Jack's. Never once did I consider it Julia's. Plus, since the whole "set of the bomb" idea was Jack's when Daniel died, it makes more sense to show the one who wanted the bomb to explode first.

Anything that happens before the Previously On LOST voice over or after the LOST logo flashes at the end is not approved by the executive producers. It's done by the ABC promo department. On the official LOST podcast they even joked about the promo that said that the next episode would answer 5 questions. They could barely get a fifth answer. It was funny stuff. So don't count on hints from the previews or in this case a teaser. I doubt any season 6 footage has even been filmed.

I was pretty sure they were just re using the shot of Jack opening his eyes when he ended up back on the island this season.

I don't see how anyone could confuse that eye with Juliet's anyway... Juliet's are quite a vivid blue.

Oh my God. Seriously? That was from the ABC marketing department, not the writers/producers of 'Lost.' Who cares whose eye it was? It means nothing.
