The Walking Dead: Exact Moment Each Person Became Infected

Luring Rick out of the woods to kill him, Shane finds himself taken out by his old friend with a swift knife to the chest. As Rick tries to explain himself to Carl (Chandler Riggs), Shane reanimates behind him and Carl is forced to put him down.

Like Randall, Shane's fate sparks Rick's season two revelation that you don't have to be bitten to turn - you just have to die. His death also ushers in the new Rickocracy era of the show.
