Oh no, I can't believe Locke is evil. In the dream Boone is covered in blood and staring off and saying "Teresa falls up the stairs, Teresa falls down the stairs" ( It was Teresa wasn't it) I would have assumed the blood on Boone to have something to do with the Teresa he was talking about, not a premonition, I mean, the plane in the dream wasn't a premonition of things to come, it was of the past, so maybe Locke interpreted a Bloody Boone to be of the past also.
I also wondered if Locke became paralysed right after leaving his fathers house, but he looks too old now to have been in the wheelchair for 4 years.
I wonder if future episodes will show Sawyer in his new specs alot or if he hides when he reads! Very friendly of Sayid to make those glasses for him, wasn't it? And didn't they have a big pile of glasses to choose from? that would not be possible, I wear glasses and I would not put them in my luggage, they would be on me.
