good point about Rick...the guy always has the best interest of others in mind, yet the loyalty of the group seems to be waning. I'm glad he pretty said, "fuggit, you guys go ahead and go off on your own if you don't like the way I do things"...that could be viewed as a defense mechanism for the point you made about him becoming unstable. Lori has already proved that she'll spread her legs the minute Rick is out of the picture for a bit, and after this current lack of support for the Shane thing, it's clear why Rick might be about to crack.
I feel the same way about Darryl and T-Dog, too...I'd love to see them get a little more screen time...they both make the show more interesting, they just need the writers to throw them a bigger bone from time to time.
