the only thing i haven't figured out is why in season 1 it took the dead hours to turn instead of minutes. i mean, andrea sat with amy overnight waiting for her to turn
People who are bit take longer than those who are killed and turn. Shane shot...turned quick. Merle shot....turned quick. Milton stabbed....turned quick.
People who are bit get a fever, etc. Probably has to infect the brain before they turn.
Goodness, how long is this stupid thread!
