Lost 5.10

Few thoughts...

What did Kate want to tell Sawyer when he asked "why she had come back?"....

Where is Aaron?  Can't wait for that episode!

I don't believe Ben is dead.  Faraday said you can't change the future.  It's not like "back to the future" when things they do in the past affect the future.  We've seen things that prove without a doubt that the past is "explaining" the future not "changing" it.  For instance, Ethan would have died without the c-section that Juliet performed.   Also, Hawkings told Desmond that you can't control destiny... that you can try and change it.. but it will keep happening (as we saw with man with red shoes).  

Also, if Ben was dead and came back to life (as with Christian and Locke) then he would have stopped aging... which could explain why Richard doesn't age.  Just a theory of mine.  So Ben is NOT dead!

Another thought... Ben couldn't go back to the 70's because he was already there.. so how would that explain Sun?  Was she born on the island?
