Great episode!
That scene where the prisoners first charged the zombies was great and Rick's, Daryl's etc. reaction to it "WTF?!?!

" was hilarious
Loving how Rick has turned out so far this season, real bad ass now.
I thought Hershel was going to die as in the last episode he seemed like he was dead from the shock/pain once Rick cut his leg of, but I am so glad that he didn't

Although he really should have died, given the amount of blood that he would have lost and the shock/pain from it especially given his age

EDIT:
One scene, which really annoyed me was Rick chasing after the prisoner. That has to be the worse inconsistency in this show so far
Just like the ammo situation, goes on about staying together, don't separate etc. yet he goes running after a prisoner in parts of the prison that he has never explored before, no idea what is around the corner...........
