Question: In the first movie the infected only stayed in the shadows and came out at night. How come the infected in this movie are running around in broad daylight?
Question: If the infected can sense the uninfected due to the uninfected smelling clean and scented (deodorant/perfume), wouldn't the closest approximation be to just stop bathing or showering, and not wearing deodorants/perfumes? Wouldn't one rather be dirty than dead? Am I over-simplifying the situation? Do the infected sense the uninfected using some other method in conjunction with the above, thereby nullifying my hypothesis above?
