Mrs. Alpert, I love your assessment of the episode. The scenes you outlined were also my memorable moments as well. I have always been a Juliet fan so I was stoked when she said "Well, here we go again". It was her moment of confronting the truth, bracing herself and moving forward. Awesome!
Also, I really am liking Island Jack. This makes me happy because it has been a long time since I have said that I really like Jack. I believe he is our hero and it is nice to watch him come back into his own all calm, cool and collected.
The other thing that really pleased me with the episode was Miles. He blew me away! I was right there with you when his dad said "I need you".
Hurley, Kate, Sawyer also played important roles and I love the comedy the writers gave us.
A classic, solid Lost episode with all the components that made us fall in love with the show in the first place.
