They keep fighting through the ads and Randall keeps crawling. Eventually Shane hurls Rick to the ground and tips a motorcycle over on top of him, then goes to get his gun back from under the fire engine where Rick kicked it. He's about to dispatch Randall, when Rick grabs him from behind and they recommence grappling. The fight comes to a lull when Rick ends up feeding Shane his teeth after all. Randall finally gains the knife and starts sawing at the ropes around his ankles. Rick and Shane are both bloody as Rick backs off and yells that he's not letting Shane make these calls any more. Shane's thoughtful, reasoned response is to grab a three foot crescent wrench -- a good twenty-five pounds of solid cast iron -- and chuck it two-handed straight at Rick's face. Rick dodges the missile, which crashes through a window behind him. One of the shattered panes briefly shows Shane as he is -- panting, shambling, bloody-mouthed, ugly, no better than a Walker, in case you've been a little slow getting the memo -- and then the hand of a real Walker appears, before the rest of it rolls out right next to Rick. Rick pins it and gives it the old forehead stab among the garbage bags, piled next to the wall, but the next thing you know a swarm of them come pouring out the window. Rick rolls the freshly re-killed Walker over onto himself and passes unnoticed, and as for Shane, well, clearly it's every ex-deputy for himself now. After a quick check-in on Beth, who's currently being yelled at by Maggie for being suicidal, we're back to watching Shane being chased by the horde. But one of them, a female, spots Randall still on the ground sawing at his roped and peels off to come after him.
