In the beginning of this episode Naomi was talking to Charlie and realizes that he is the "Dead Rockstar from Driveshaft" She goes on to say that they made a big deal about him dying. They had a memorial service and released a Greatest Hits Album...

If they have only been on the island for 90 days, don't you think in the real world it would take longer to accomplish all of this..

Could this be a clue to the fact that time does pass differently on the island than in the real world..

Just something that stuck out to me when I rewatched the episode and thought I would find out what you all (everybody) thought..
