Our main island Survivors cross paths with the Others in search of Michael, a meeting which causes Jack to take action. Charlie's hallucinations and erratic behavior lead some of the Survivors to believe he's back on heroin - but is he? In our flashbacks, we learn what lead to Jack and Sarah splitting, and how Charlie knows all too well the burden of being a junkie father as he watched his brother from afar. These episodes lead to side discussions on certain aspects of the show treading water in this portion of Season Two, and a great featurette from the bonus feautres of the box set adds some valuable insight into all the care each LOST episode has put into it.
