Re: Carl - someone else is probably going to get themselves killed because of his stupidity.
Somone already has - Dale!
After re-watching last night's episode - it seems like Shane's plan was pretty scattered at first. I think he led Rick out there to goad him into killing him. That was his true end-game: suicide. But he needed Rick to do it and carry it with him for the rest of his life.
The guy in Talking Dead alluded to this too, but I don't think that's what was going on in that scene. I don't think Shane actually wanted or expected Rick to shoot him. I think he was trying to prove his point very vividly - that Rick was not able to protect his family or lead thr group because he was scared to make the hard choices. He's basically taunting Rick - 'hey, I'm a threat to you, your loved ones, and everyone else in our group, I brought you out here to kill you, and you're STILL not willing to fight to protect what's yours?'
It's as if Shane was almost trying to convince himself that Rick was not worthy. Even as far as he had gone to that point, he still needed to cement his resolve. And I think he would have done it too, if Rick had not gone all K-Bar on him. (That was beautiful)
I'm certain Glenn and Dale recognized Randall was the walker. It took me two viewings to be sure myself.
Yeah, that last scene in the field with the encroaching walkers looked amazing on HD widescreen.
