John Locke makes me so, so sad.
I hadn't seen much of the first season, but I have watched all of the second season. I have always thought of John as a very strong, intelligent man. But now I am watching the 1st season thanks to Netflix. The episode where John is talked down to by his boss, where you find out he is in love with a phone sex girl and that sad, sad part where the Aussie wouldn't let him go on the walkabout.
I cried very hard in that episode. It was like finding out your parents make mistakes. There is not much sadder then finding out a strong man is actually weak.
