Okay, I rewatched it last night.
In regards to timing: At the beginning Jack makes it a point to say that in the two months hint hint that they have been on the island, no one has gotten sick.
Then when Claire is talking to Libby she makes a point to remind everyone that two weeks after the plane crash Ethan took her. She was gone for two weeks so that would mean that Aaron is actually a little less than one month old.
So then they show us the hatch and it's in shambles, lights out, cobwebs. etc. and especially that nursery.... just seems to me that it would take a lot longer than 1 month for it to look that way. Not to mention the hatch door is grown over. Of course, it doesn't actually show Ethan taking her out that door in the episode, so there very well could be another door to the outside that wasn't shown, but she remembered how to get to it after she sees that weird log where they were talking.
Hmmmm....I say that there is definitely something up with time on the island.
Why would they go to all the trouble of basically reminding us that it had only been one month since Claire was in that hatch last?
I know someone mentioned this earlier but what if when the timer went down to zero, that made *something* happen with time. Zeke and his crew appeared in the woods before the timer went to zero. Bear with me: they could have come back, put their disguises up, timer goes down, they bail, I don't know. I'm just reaching here, somebody help me out.
