The knife didn't hit Hurley. It his some thing that looked like a pie tin he was holding in front of him.
Other things I noticed:
The guy Eddie was wearing a Geronimo Jackson shirt. I believe that band was named in an earlier episode. Not sure of the significance but just something I picked up on.
Seeing Boone again makes me so happy.
I saw naked Desmond ass though I was kinda hoping they'd pan down!
