"radiomd", one of the commenters at Alan Sepinwall's blog "What's Alan Watching" (link to the left, my bots!), made this observation about the end of 'Life On Mars' (and by extension, the episode before last of 'The Sarah Connor Chronicles'):
it was a tough week for characters played by Dean Winters. You see Dean Winters go near a dock, as Ken Harrelson would say, he gone.
That could become some kind of TV trope subset - "Dean Winters character on a dock will die".....
