Dale has kinda become the Debbie Downer of the group. I doubt he makes it to Season 3... Which sucks because I liked him in Season 1.
The glass peeling the zombie's face was epic. I think that was Lori's first official zombie kill, so she did pretty well for herself.
The thing about the love triangle we've got going on is that I think Lori just convinced Rick that Shane is infact dangerous and will not be just willing to live and let live. I hate it because I see Shane dead before the end of the season, and he's the strongest male character. I like Rick but Shane's craziness adds a lot to the dynamics of the show.
I think we may start to see some more living characters with the whole Randall arc. Will be interesting to see if he becomes a character or if he dies off fairly quickly.
