Here the big one if anyone remembers. Back in the episode where Shane is killed they work out that people are already infected but in this episode they say it's infected blood. Remember Rick kills Shane then comes back as a walker. Plus why was that kid a dumb ass. Could've easily killed 3 or 4 then left them to turn. Plus I was waiting for the A team to appear. 50000 rounds about 15 folk dead. If the hilltopers get wiped out its probably best. They're idiots.
