I was trying to find a clip to post from the TV show that would show the similarities...but it seems hopeless. I do remember they showed Shane and Rick walking on a hill in silhouette though it was more nighttime than what Clem experienced (dusk). But I still feel this is a more intriguing and plausible ending. Sure, we had Hershel and Glenn to tie in the TV show, but the whole point of post-credit scenes is to lead into a tie-in or sequel of sorts. To know that Clem could have joined the TV show's crew but decided to run off instead after watching Rick kill Shane would be dynamic!
