Judge, Jury, Executioner - S2-E11
Corrected entry: Where did the zombie that attacks Dale come from? Dale is walking in a wide open field and there appears to be enough moonlight he can easily see the cow that has been attacked. Yet the zombie manages to sneak up on him? There was no long grass or crops for the zombie to hide or enough time to just appear from nowhere.
Correction: There's a pile of dead zombies that Dale walks past that the camera stays focused on for just a bit, as opposed to just panning by. Usually a foreshadowing shot.
