Chupacabra - S2-E5
Continuity mistake: Daryl ripped off his shirt to wrap around his wound, and was left in only his vest. Except, a shot later, he's seen wearing his shirt again, cutting off the walker's ears. (00:25:30)
Answer: Walkers are attracted to noise, they can tell who's dead and who isn't dead, in S1 when Rick and Glenn cover themselves in walkers' guts they're able to get far by walking through the herd of walkers because they smell like they're dead, but as soon as the guts get washed off by the rain the walkers immediately attack them, if you draw attention to yourself they will attack you which we've seen that many times throughout the series that it's not always successful. Whether you're covered in guts hiding under dead corpses or under a car.
