At Walker Stalker Con this past weekend, Andrew Lincoln revealed what the three hand weapons that Rick Grimes would carry if he ran out of bullets would be. Lincoln said, "A stone is pretty good, that's worked very well for me in the past, an eye gouge, just thinking on my feet here, and any sharp stick." Lincoln also revealed that his character will develop another unusual method for killing walkers. "I'm going to not spoil anything, but Rick develops a new technique this season for dispatching people," said Lincoln. "And it isn't a gun, it isn't a knife, it's something quite different. And I look forward to hearing your reactions, because I was shocked." What do you think Rick's new killing technique is? The Walking Dead Season 4 airs on Sunday nights at 9 PM ET on AMC.
