Didnt realize you'd posted that particular comment (read the thread in one sitting), so i'll change silly to highly unlikely IMO, as you routinely posit pretty on point scenarios.

Has TWD comic ever covered the smell issue? The show has never made a big deal of it.
You'd think for the smell to overwhelm DD, who lives in NYC, a city rife with sensory input, it would have to be at a level where normal humans would have huge issues with it themselves (surgical masks, bandanas, gas masks being the norm).
