WARNING: The following article contains major spoilers for “Something They Need,” tonight’s episode of AMC’s “The Walking Dead,” which as of publication hasn’t yet aired on the West Coast, as well as the Image Comics series.

For readers of "The Walking Dead," "All-Out War" is arguably the centerpiece of the comic -- an arc that wraps up the Image series' most prominent conflict to date and sets the plot in a completely different direction for the next few years. It also involves an enormous cast of characters, with citizens of Alexandria, The Kingdom, and Hilltop Colony going to battle against The Saviors.

But it looks like the AMC adaptation is gearing up for an even bigger confrontation -- one that likely won't be wrapped up until well past next week's seventh-season finale. In addition to the four main communities, two new groups are entering the fold. We know that Rick has already sought the help of the mysterious junkyard gang (do they have an official name yet?), and then, there's Oceanside.

In tonight's episode, Tara breaks her promise not to reveal the group's whereabouts, telling Rick about them so they can invade the secret community and take their weapons at gunpoint. Although Rick wants both Oceanside and Alexandria to work together, it's still a bad way to start off their relationship. He essentially bullies them into doing something they don't want to do.

Regardless, by the end of the episode (and a walker attack that the Alexandrians help stop), many of Oceanside's denizens (though not all of them) have joined the fight against The Saviors, weapons-supply and all. That means the junkyard people are also in, and that we can expect an All-Out War that truly lives up to its title. More on this and the rest of the episode in tonight's full recap and review.
