"The Walking Dead" is a show that sometimes creates more questions each episode than it answers. The same could be said for its comic-book source material, but one particular incident from last season has kept viewers speculating, due in no small part because the scene never happened in the books. Of course, I'm talking about "the whisper" – CDC scientist Dr. Jenner's last words spoken into the ear of Rick Grimes.

Well, it looks like Andrew Lincoln, who plays Rick on the show, isn't going to give us any clues. Apparently, he hasn't even told his wife what Jenner said; that's some serious commitment.

"This is a scientist who seemingly held all the cards to what this epidemic is about and I do think, you know, you would imagine he would have something of value to say on that matter," Lincoln told The Washington Post. "Well, he chose to kill himself."

So, while the entire CDC scenario felt a bit out of place, maybe the whisper holds the secret to how the entire outbreak began. Supposedly, the details of the conversation will spill out this season, but in the meantime I've taken the liberty of speculating on what Jenner muttered.

"...Rosebud."

Think about it: Jenner is a strange, seclusive man, but when his time comes to die he just mumbles something about a sled. Speculation that just leads to eternal speculation – brilliant!

"Why were they all in a church? Were they always dead? I don't get it."

It's one of the great questions, Dr. Jenner. We don't know, either.

"There is no cure."

Probably the most likely. Jenner has discovered that whatever turns the dead into brain-hungry ghouls isn't going away – ever. Hence, he's more than happy to blow himself up.

"A thing is not necessarily true because a man dies for it."

Ok, so Jenner probably didn't quote Oscar Wilde, but the statement rings true. Just because Jenner was willing to blow himself to kingdom-come doesn't mean the living are doomed.

"I just saved a ton of money on my car insurance."

Way to work in some advertising revenue, AMC.

"Dude, seriously, how is anything the Governor does going to be allowed on basic-cable TV?"

Yeah, good question.
