YES! I thought for sure when they showed her walking outside that she was going to have little Charlie hidden under her coat!
So if they prevent the "incident" from happening, it means the Oceanic flight never crashes, and they all land safely in LA, right? I'm wondering if this is going to set up a moral dilemna for all of the Losties - if that happens, it means their lives resume where they left off pre-flight: Kate is going to jail; Sun & Jin are miserable and not pregnant; Sawyer is unwilling to commit; etc, etc, etc. Make me wonder if they would REALLY want to do this. Wouldn't it be funny, though, if that is what the series finale turns out to be - the incident is prevented and they are all shown landing in LA in 2004.
And if the plane crash never happens, does that mean we see Charlie and Boone again?
