Like many, I was glued to my television on Sunday nights watching AMC's The Walking Dead. Yes it's unfortunate that the season was only six episodes but there's no point in complaining about that (or the wait until season 2 begins). As much as I've been waiting for any new information on the show, I've also been waiting to have a proper discussion on what happened in the final episode. With the release of the season today on Blu-ray and DVD and with the millions of viewers in the ratings, I thought now would be a good time to talk about it and not be too concerned with spoilers. 

• Shane and Lori argued in the rec room and that he attacked her. 
• Everyone in Washington D.C. is gone. 
• The location of a cure. 
• The location of other survivors, perhaps leading them to the prison, the Governor's city or Hershel's farm. 
• The location of the French scientist that was close to the cure (hopefully not in France). 
• Their blood samples showed some or all infected with virus. 
• He wasn't a real scientist but just the janitor there. 

He told Rick that everyone is infected and that when they die they come back to life.

The most assumed idea I've heard is he told him about the pregnancy, though it seems the most likely so it could quite possibly be something else.

"I just farted - I'm sorry..."

He told him that Lori is pregnant 
 
It would have been shown in her blood test

Remember, Kirkman said what was said would shock everyone. None of the theories that have been mentioned before are really shocking.

"I saved money on my car insurance by switching to Geico!"

" "I saved money on my car insurance by switching to Geico!" "

" He told him that Lori is pregnant, It would have been shown in her blood test "

He told him "your wife got knocked up by your best friend" congratulations

"He told Rick that everyone is infected and that when they die they come back to life. "

"save the cheerleader, save the world!"

I wouldn't rule out the news of her pregnancy as his whisper. Kirkman didn't explicitly say who would be surprised. Just because fans of the comic already know doesn't mean everyone else watching does.

" "save the cheerleader, save the world!" "

" @SupremoMaximo said:

" "save the cheerleader, save the world!" "

Hahahaha priceless! "

Maybe he told him he needs to save the world from M.A.D. (Mutual Assured Destruction). MAD could still be at play and presents an even greater danger than the zombies. I'm not sure if the comics have brought it up before since I'm only up to issue 65.  An automated response system from Russia or another nuclear-capable country should already have responded to the zombie apocalypse. This could mean there are people in the other nuclear armed countries, including our own, keeping the nukes at bay.

"I'll always love you, Rick."
 
:P

I think him telling Rick that everyone is infected is probable, especially because it sets up Rick to announce "WE ARE THE WALKING DEAD" Just like the comic. And since Rick can't go dig up shane to figure this out, this seems like a good way to get that revelation out in the air.

I'm willing to bet he just said ''psspspspsptstspsps'' like in the cartoons, and Rick's facial expression was responding to this man's insanity. 
 
Either that or ''I know who you really are, Andrew Lincoln!''

" He told Rick that everyone is infected and that when they die they come back to life. "

Who says that Lori has to get pregnant on the TV show.  They have already gone off script from the comics and I wouldn't be surprised if they just dropped that angle from the show.
If it is the pregnancy then I don't think they handled it very well.  I would really expect Rick to be shooting some knowing glances at Lori after finding out this news especially when they are all sitting in their vehicles in the parking lot after the CDC fireworks.

"never gonna give you up, never gonna let you down."

I have never read the comic, but they may change it.

"We probably would be watching Breaking Bad season 4 right now if AMC didn't push it back for some reason."

he said 'i read the comics, your wife dies in issue 48....'

"I killed...Mufasa!"
 
No but seriously I think it's going to be that they're all infected and slowly dying without the cure.

"Rick, I just save a bunch of money on my car insurance...,"

We created and released the virus....my bad dude.

As soon as the ep was over I hit up a comic forum (here too I think) to post my idea of what the Dr said and I still stand by it: That  Andrea 's  pregnant. I say that since she was the only one to have been given the blood test on screen.

"it's over duder..."

It's a secret. You will only find out in Season 2.

Can't wait for season 2 !!! :)

"I see dead people."

"Any child born is a zombie"

Um...season 2 is coming in July not october...they announced it.
