Take note, everybody. For, one day, there may be a zombie apocalypse. And should that happen, you're going to want to remember key terms and phrases that sum up your predicament. We're introduced to one of those terms within the first minute of Episode 6 of The Walking Dead -- and it's "biter-gram." What's a biter-gram, you ask? A biter-gram is when you send someone a message using only body parts of the undead and some ingenuity. Michonne, now on the run from Woodbury, sends the first ever biter-gram to Merle (who comes up with the phrase) and the three goons sent to track her down. Using some limbs, she spells out the word "GO" and leaves a zombie's back on the ground. Get it? Go Back. What a smart (and gross) lady.
Once Merle has stopped laughing at his (admittedly) funny joke, he admonishes one of the goons, Garguilo, for being too soft and freaked out (which he is). Then Merle starts waving his gun around and trying to taunt Michonne out of the surrounding trees, which works remarkably well because Michonne immediately leaps out of one, beheads one goon, slaughters another, leaves Garguilo alone and runs off into the brush, pursued only by Merle, who shoots her in the hip.
Back in the prison, we pick up where Episode 5 left off: Rick has picked up a phone that unexpectedly starting ringing. On the other end of the line is a woman who claims she has been calling the phone since the zombie uprising. She says that's she's safe, but refuses to say where. Rick explains that he has a son, a newborn baby and a good group of people and asks the mystery woman if they could take more people where she is. She says she'll consult with her group. Rick begs her for help. She says she'll call back in two hours. "Please," Rick pleads, more broken than we've ever seen him. "We're dying here."
Rick briefly rejoins the rest of his group, who are all sitting down to eat together. He checks on Carl, explains that he's cleaned out the boiler block and goes straight back to work. Sometimes nervous breakdowns make people crazy productive!
Back in the woods, Merle is telling Garguilo they have to move before walkers arrive, attracted by his gunfire. They take off in pursuit of Michonne, after insuring their freshly dead friends can't "turn" (that means stabbing them both in the head -- even the disembodied one. Yay!)
In Woodbury, Andrea and the Governor are talking on the street. Andrea tells him that she understands why "the arena" had to happen in Episode 5, but that it's "brutality for fun" and that "the world's brutal enough already." She also says she wants to stay in town regardless and she'd like to help guard the wall. The Gov seems cool with that.
Rick gets another phone call, as promised, but this time it's from a man who asks Rick how many people he has killed. Rick says four and explains how they were all justified killings and out of wider concern for his group. The man asks how Rick lost his wife. Rick is confused as to how the man knows he's married and says he doesn't want to talk about it. The man immediately hangs up. Rick loses his shit. Fair enough.
In Woodbury, Andrea has joined a young woman (with a really fancy bow and arrow) overlooking the wall at town's end. They bond over having to kill their own zombified relatives (naturally). As a walker approaches, the girl makes a weak attempt the kill the undead guy with a couple of arrows. Frustrated, Andrea jumps over the wall and stabs him in the forehead instead, looking thrilled with her kill. The girl is pissed. "What are you doing?" she yells at Andrea. "This isn't a game!"
In the prison, Hershel hobbles over to where Rick is, thanks him for saving his life (by hacking his leg off with an axe, in case you've forgotten) and says that Lori was sorry and planning on talking to Rick about it. Rick tells Hershel about the calls he's taken. Hershel picks up the phone and hears only static -- no dial tone. He offers to sit with Rick while he waits by the phone (and has a facial expression that suggests he thinks Rick has lost his mind). Rick says no, so Hershel leaves.
Meanwhile, Merle and Garguilo are still in pursuit of Michonne, who manages to jump out of nowhere again and injure both of them, before all three are attacked by the undead. Garguilo stabs one in the head, Michonne manages to get covered almost entirely in intestines (nice) and Merle uses his stump as a bayonet. Whoop! By the time it's over, Michonne has disappeared again.
