The episode opens as sisters Andrea (Laurie Holden) and Amy (Emma Bell) are fishing for the survivors in a nearby quarry lake, discussing their childhood and hopes that Florida, where their parents live, was not hit as hard by the zombie epidemic.

In Atlanta, Rick Grimes (Andrew Lincoln), Daryl (Norman Reedus), Glenn (Steven Yeun) and T-Dog (IronE Singleton) have discovered the severed hand of Merle Dixon (Michael Rooker), Daryl’s brother, where Rick had handcuffed him on the roof of a store. They follow a trail of blood to show Merle had killed some walkers and managed to cauterize the stump of his hand before the trail goes cold.

At the survivors’ camp, Jim (Andrew Rothenberg) begins digging holes, refusing to explain why. As the survivors press him, he lashes back at them, forcing Shane Walsh (Jon Bernthal) to restrain Jim.

At the camp, the other survivors’ are enjoying dinner when a horde of walkers suddenly appear, biting several of the members including Amy and Ed Peletier (Adam Minarovich). Rick and the others arrive in time to quell the walkers. Amy dies in Andrea’s arms, and as the others stand around in shock, Jim recalls why he had dug those holes.

“Vatos” was directed by Johan Renck and written by Robert Kirkman; this episode became Kirkman’s first writing credit for the series. “I was pretty happy that the first death in the show was in an episode that I got to write,” he stated. “That was kind of cool.” The episode’s script was heavily modified by Kirkman and series creator Frank Darabont prior to airing. Neil Brown, Jr. initially collaborated with producers on directing the episode but eventually pulled out of the project.

Principal photography for the episode transpired at the Goat Farm Arts Center in the West Midtown neighborhood of Atlanta, Georgia. “Vatos” features a sequence near the conclusion of the episode, in which a horde of walkers invades and attacks the campgrounds. The scene was written by Robert Kirkman, who based it closely on a similar sequence in the comics. Kirkman stated that he was very excited to develop the sequence and added that it was a familiar task for him:

It was very exciting. I got to write the attack at the end of the episode—which was very much something that happened in the comic book series—so I knew I would be revisiting something I had already written. But as we were in the writers’ room, when things started shifting which led to all this new stuff that wasn’t in the comic book series, I thought that was great because it wasn’t me writing the same-old same-old or rewriting something I had already done and trying to make it interesting for myself. It was really an entirely new story: getting the gang members in there and getting to write Daryl […] which is one of my favorite characters on the show, despite the fact that he’s not in the comic book. It was a blast.

This episode marked the last regular appearance of Emma Bell (Amy), whose character was killed off in the conclusion of the installment. Greg Nicotero, the show’s production designer, enacted the walker who bites Amy. Bell stated that Nicotero placed a skin-colored prosthetic around her neck, which consisted of a layer of red viscous liquid and a hose. Once it was bitten into, the prosthetic exploded and resembled a severe flesh wound. Kirkman expressed that it was difficult for him to remove Bell from the cast but was thankful that she understood she would only be limited to a certain number of episodes; he stated:

It’s something that’s very difficult for me. Because it is lines on paper when I do it in the comic book series. It’s like, ‘Oh, okay, Charlie Adlard […] doesn’t have to draw that arrangement of lines anymore, that person is dead.’ But it’s very uncomfortable for me to be on set, because I see these actors that are there and, in the source material, I have killed all but two of them. I walk through the set and I’m like, ‘Yep, killed that one, killed that one, killed that one.’ And it is firing those people. I feel really bad for Emma Bell, just because she was great and I would have liked to have had her in the show. But, you know, this is The Walking Dead, characters have got to die. Thankfully, Emma was brought onto the show with the understanding that she was only going to be in a certain number of episodes and she knew that she was going to die from the very beginning. But it doesn’t really make it any easier large metal water bottle. When they were shooting those scenes, I had to fly to Comic-Con and so I wasn’t actually there for when she died. But it was very emotional on set and I know that she was very upset about having to leave the crew and the actors. You kind of become a family when you’re doing a TV show and it’s a little upsetting to have to get rid of somebody.

“Vatos” attained general acclaim from television critics. James Poniewozik of TIME asserted that the episode successfully made the viewers experience the daily life of the show’s characters, and HitFix’s Alan Sepinwall felt that “Vatos” was the strongest episode since the series’ pilot episode glass liter bottles. In his 7.9 out of 10 star review, Josh Jackson of Paste wrote: “The whole spectrum of human nature is on view when civilization is stripped away—the bigger the immediate threat, the more varied the response. And it’s this balance between action/horror and personal drama that makes The Walking Dead so compelling.” Los Angeles Times writer Gina McIntyre felt that Kirkman “seemed right at home adapting his characters for the screen.”

John Griffiths, writing for Us Weekly, felt the installment was haunting enough to “make viewers leave their lights on afterward”, and opined that the character development and the progression of the storylines served as the episode’s highlights. John Serba of The Grand Rapids Press stated that “Vatos” was the most emotionally poignant episode of The Walking Dead so far. Expressing similar sentiments, IGN’s Eric Goldman evaluated the episode as “strong”, ultimately giving it a nine out of ten, signifying an “amazing” rating. Leonard Pierce of The A.V. Club, who issued the episode a B grade, was less enthusiastic than the general consensus. Pierce felt that the bulk of the episode was “mushy” and concluded that it “didn’t solve anything involving the ongoing plot and introduced a bunch of arbitrary, needless complications that had no payoff, [and] bogged it down quite a bit.”

Critics praised the interactions between Amy and Andrea. Serba asserted that Kirkman effectively set up Amy’s death at the beginning of the episode, and added that it established a sisterly bond. Serba also acclaimed Laurie Holden’s performance; he stated that she “powerfully conveys her grief and despair.” Pierce avouched that the opening sequence was likable, while Michelle Kung of The Wall Street Journal summated that the concluding scene was “an emotional release after a tense build-up.”

Critics were divided about Rick Grimes’ return to Atlanta, as well as his stand off with Guillermo and his gang. Scott Meslow of The Atlantic compared Grimes to Mad Men‘s Don Draper, and questioned his character development: “So far, every decision Rick has made has been both within his code and consequence-free,” he said. Pierce opined: “Dramatically, this whole sequence plays out pretty hokily. Guillermo’s dialogue is ridiculous, and the entire storyline plays like something out of an episodic social-lesson-of-the-week show. Since nothing ends up coming of it from a plot standpoint […], it’s hard not to think of it as one of those comics where two superheros [sic] have a big fight scene that turns out to be mistaken identity.”
