I was puzzling that out myself.
I **think** the mysteries were:
1. Jack's tattoo (which I never cared much about anyway)
2. what happened to the stewardess
3. what happened to the children
I could be wrong, but that's about all I can make of it.
I thought the "watching" must have been Juliet's trial.
Yeah, the little girl asking about Ana Lucia was a bit forced in. I can only guess that it was supposed to show that hadnt been "brainwashed" or complicit in any way, although Id have to imagine that knowledge would have been kept from the children anyway even if the adults had full knowledge of what transpired.
Im really curious to see how they explain away Ethan's sociopathic behavior, particularly the hanging of Charlie, if we are supposed to be led to believe that the "others" are only acting with the best of intentions. To be honest, I dont buy for one second they had Ethan completely planned out from the beginning. All this new "surgeon" business is clearly a ret-con.
I also didnt get Tom telling Jack that people who live in glass houses shouldnt throw stones. Wasnt it Tom and his buddies that grabbed Walt, fired at Sawyer & Michael and blew up their boat? It seems to me the "others" initiated the violence.
Seems like Im just full of negatives this week. Sorry. Ill try to find positives next week to talk about.
