As I noted in a blog post:
I wanted to verify the exact whisper to Rick from Edwin Jenner, to prove what Rick knew and when about the state of the Walkers, and I played the Walking Dead bluray, raised the center channel on my home theatre and dropped the remaining channels, and played it very loud. From 37:30 to 37:34, Edwin says two things; "It's in your blood." and "We're all carriers." A third sentence is inaudible even with channel isolation due to surrounding noise.
This page noting that the whisper is inaudible is factually incorrect... its inaudible at normal listening levels, but is intact in the audio track if you selectively listen to the center channel (Aperion Audio Intimus 5C on an Onkyo SR-605 from a Sony Playstation, original series bluray.) The two sentences are perfectly clear.

Just to provide more information of how the Edwin Jenner whisper to Rick can be heard: Onkyo SR-605 center channel +15db, other channels -15db. 70% maximum volume, via Aperion Audio Intimus 5C center speaker. Source original S1 bluray played on Sony Playstation 3.
