Not much time for an update this week as I'm on an abbreviated lunch here at work, but here goes:
1) "Catch 22" was fantastic in my opinion. The whole moral dilemma faced by Desmond of sacrificing Charlie to try to rescue the person who he though would be Penny was great.
2) Good Desmond back story, but there's still so much missing... Like, why did he join the army? What is he court-martialled? Does he meet Sayid in Iraq? (I would imagine that would too tempting a possibility for the writers to pass on...)
3) Charlie is going to die soon.
4) The Kate/Jack/Sawyer fault lines are building for the season finale. The writers have put so much into that triangle that they can't afford to totally back off on it.
5) Jin is capable of killing Charlie and possibly Sawyer but I don't think he will. Eventually, he will find out about Charlie's staged attack on Sun, but he wouldn't kill Sawyer. Might make life difficult for him, but not kill him...
6) Tonight's episode sound's great. Its called "D.O.C." ("Date of Conception" and promises to answer the question of paternity for Sun's baby. I'm going to predict that the baby is Jae's (the guy that suicided) but that she never tells Jin. After tonight, there are 3 more episodes, followed by the two-hour season finale. The finale is supposed be "Jack-centric."
Happy watching!
