Please discuss this episode here.

Well, I'm current through this episode.  But it's really a lot less fun if no one else is watching and posting.  

I did enjoy seeing Sawyer and Kate playing Truth or Dare.  Yum.  And I had forgotten that he killed that guy who's been in everything.In light of this incident, I would think he qwould have been a bit more hesitant to kill Cooper.  But I guess it was pretty abvious that he was the REAL Sawyer.

I'm watching, I just haven't had time to update on some of the other episodes yet.  

I think he was motivated to kill Cooper only because of the reaction Cooper had to the letter.  Pure rage at knowing this SOB didn't care that his parents were dead because of his meddling caused him to snap.  He still seemed very hesitant to kill the sweet shrimp guy IMHO even when he did it and his reaction right after doing so (shaking, facial expression) showed that he really didn't feel at all at ease about what he did... and his getting sick after killing Cooper shows me that they're painting him as one kind of "tiger" (a killer who doesn't "change his stripes") when really he isn't.
