This is probably old news, but I haven't seen it mentioned.Did anyone notice Walt on the milk carton that Hurley was drinking in his dream? I saw a picture at Sucks and wasn't sure it was a fake. So I went back to watch the tape and it sure does look like him.
Yes it was a dream sequence, but Hurley doesn't know Walt is missing.
My son spotted it immediately, and we zipped back to confirm. It's Walt alright.I think that's just another writer's joke, and not really significant to the plot.
Sort of like the stuffed polar bear, or Locke, after watching the Orientation film, looking the camera dead in the eye and saying, "We're gonna have to watch that again."
The writers know about the rabid fan base. And they like to throw us a laugh every once in a while. Just another reason to love love love the show.
