Oh yea, I remember the scientist whispering "something" in Rick's ear. You might be right. It will be interesting to learn exactly how they all got infected.
With THIS show, it's not even so much that the zombies are scary (cause they aren't especially scary), it's that the storyline is always so intriguing and the acting is good. Oh, and isn't the theme awesome?

I love how the music builds in suspense at the very end of the episode. Cool!!
