The score is mostly to do with the walking along the beach shirt undone shot.......
Loved see the actor who plays Mick do a great job of playing him mortal, it was more than just the scoffing of food and bleeding that convinced me, IMO he did a great joob to change his presence on screen to a more vunerable one .
I too like joseph, he has much to give as a character (as this episode illistrates perfectly) - although I have a sneaking suspision that in later episodes the writers will spice up a 'judas' type storyline........after all its the people you love & trust the most that have the capability of hurting you worse than anyone.
