In it, Glen, Rick, and Hershel are surrounded by an advancing horde of zombies, and they spend a couple minutes debating whether and how to save a teen who's leg is impaled, though that teen was earlier trying to kill them?
Well, yes. The point is, this team are not heartless, soulless bastards. They AREN'T Shane or the people who attacked them. Hershel believes everyone has a reason to live as he is a man of God.
The foreigners who find that trio in the bar attempt (unsuccessfully) to get their weapons pointed at the guys, though that's really unlikely to result in them getting them the info on the group's farm hideout. (You can threaten the hostage to get his info, but that's it - the hostage knows you can't actually go through with the threat, or you'll never have the info. Better would be to leave quietly, and secretly track the trio back to wherever.)
This conversation was the best bit about it. Desperate men. It showed that Rick had changed and was prepared to defend his clan from the outside...that the real danger was not walkers, but
humans. That in fact, these new guys were just desperate - although admittedly they were painted rather poorly - illustrated by the fat guy urinating.
Laurie, the pregnant mother, tells nobody when she leaves her child and risks her life in an attempt to find her husband - who may be dead, or not where she expects him.
Agree on this. Most of us seem to be baffled by Laurie's actions here.
And the people who came looking for the two 'bar intruders' behaved in a way I also find unrealistic, speaking right outside the door for Rick, Hersh, and Glen to hear, then shooting wildly (and unseen) into the bar, rather than just let people exit and shoot them (or force a surrender).
You're making the mistake of thinking these are cool calculated people. Would you be? In a village about to be overrun by Zombies?
And Glen shat his pants and froze behind the dumpster, then fired off his shotgun from a distance, though he was still apparently effective at hitting the brain and stopping the zombies.
This was explained in the episode. But yea, Glen was a crackshot later, but the threat was human when he froze.....
Laurie evades one attacking zombie and, while stopping and staring at the body, is attacked from behind.
See above on Laurie.
Carol, distraught over her zombie-daughter's death, wanders a short distance from camp to punch & pull grass - despite the typical (not-so) surprise danger of pop-up zombie attacks?
Grief. Do you know it?
Despite his increasing instability & threatening action to the group, nobody has gone out on a mission with Shane and killed him, simply reporting back to the group that he got bit or accidentally shot himself?
That's because no-one wants to believe what Shane is becoming! Plus of course there are some people who believe he is right. Shane is an emerging threat and was once the trusted left-hand man of Rick. They're like best friends! So why would they go out and kill him? THAT would make no sense.
Who would burn the calories and waste the energy to bury those zombie bodies? Was it four graves they dug? I just can't believe that stuff.
Disease, infection. SMELL?????
