Here's everything we know about the mysterious group in 'The Walking Dead' who took Rick in a helicopter

On "TWD: World Beyond" premiere, members of the CRM pay a visit to the Campus Colony community in Nebraska from an undisclosed location. During a discussion with Hope and Iris, we learn Kublek is a Lieutenant Colonel for the CRM. That's how she introduces herself to Felix.

Relive the moment: Kublek introduces herself 5:10 into the "TWDWB" pilot.

We don't know anything about this character yet, but Kublek tells Felix he was supposed to join in visiting the Campus Colony community.

We're not sure whether or not she was lying.

Relive the moment: Kublek mentions Beale 5:30 into "TWDWB" premiere.

Referred to as the "Alliance of the Three," the CRM is comprised of communities in Portland, Oregon; Omaha, Nebraska (which also included the Campus Colony); and another undisclosed location in New York.

The Campus Colony consisted of 9,671 survivors.

Kublek hands Iris and Hope a coded map of New York state halfway into "TWDWB" premiere.

While that doesn't help narrow things down, you may recall that Michonne found Rick's boots and a drawing of Judith on her final episode of "TWD." In her search for more clues about Rick's whereabouts, she came across a paper filled with locations. One of the two that was made visible mentioned a shipyard in New Jersey.

If you're familiar with Jersey, the largest one in the United States is Port Newark-Elizabeth Marine Terminal near Newark Liberty International Airport. It's a short trip from New York City.

A second prominent shipyard is in Camden, New Jersey across the Philadelphia, Pennsylvania border.

Revisit the moment: Watch Kublek hand over her map of New York 32:50 into "TWDWB" premiere.

This was a shocking revelation. In the comics, the largest community we ever met was the Commonwealth. Situated in Ohio, that group is comprised of 50,000 people. They were just introduced on "TWD" season 10 finale.

Relive the moment: Kublek shares how large the group is 43 minutes into season one, episode three of "TWDWB."

Kublek tells Iris and Hope she's a little bit older than them.

"She's away from me a great deal and that makes me scared sometimes," Kublek said. "She's helping to protect the civic republic."

Kublek doesn't share her name, but it has us wondering if she's the young woman Al met on "Fear TWD," Isabelle.

Relive the moment: Kublek reveals she has a daughter 31:42 into "TWDWB" premiere.

Isabelle is a soldier in the CRM, who was introduced to us on "FearTWD." She captures Al on season five, but eventually lets her go.

Al communicated with Isabelle again, briefly, on season six, episode three via walkie.

You can see Isabelle for a majority of season five, episode five of "FearTWD."

"You don't let anyone in or out," Iris tells Kublek on "TWDWB" premiere.

That would help explain why Rick Grimes hasn't been able to return to his friends and family in more than six years. The place may be heavily guarded.

Relive the moment: Iris calls out the CRM 31:25 minutes into "TWDWB" series premiere.

After Iris discusses her skepticism of the CRM aloud to her community, Kublek and her soldiers wipe out the population of more than 9,000 inhabitants.

A few episodes later, we learn they were killed because they were considered a threat to the CRM. These guys mean business.

Relive the moments: Kublek oversees the destruction of the Campus Colony community 50:53 into "TWDWB" series premiere. She later discusses the decision to kill its inhabitants 40:55 into season one, episode three.

When Barca questioned killing over 9,000 people on the series' premiere, Dublek had him remanded to the CRM's Health and Welfare Complex until he was "deemed ready to serve again."

It seems like the group isn't big on second chances, though. Barca wasn't going to be reinstated into the CRM military. Dublek said he would have a "labor-oriented" position. Perhaps that would involve working with crops or some other menial task in the community.

Unfortunately, Barca expressed little interest in serving the CRM again and was told he would never leave the complex. As he was pulled from the room, we heard an audible "thump" offscreen, suggesting he was knocked out. Not reassuring.

Relive the moment: See Barca face the consequences of standing up for himself 42:20 into "TWDWB" season one, episode three.

Kublek tells Barca that the CRM has electricity, water, medicine, transport, currency, schools, courts, agriculture, and something she refers to as "the Council."

They're also making their own bullets. It seems like the CRM are living the high life.

Relive the moment: See Kublek go through the list of everything the CRM has 42:31 into season one, episode three of "TWDWB."

When speaking with Hope and Iris, Kublek mentions that she could go to jail if anyone finds out she gave them a coded map of New York state.

She wasn't joking about the jail bit either, assuring the sisters the CRM actually has those.

"Are you for real?" Hope asked skeptically.

"I am," Kublek said.

Relive the moment: Kublek tells the sisters about the CRM's jail 33:13 minutes into "TWDWB" series premiere.

We don't know how many helicopters they have, but we know from "TWDWB" and "FearTWD" that they have a few that go around on patrol.

Rick has seen helicopters throughout "TWD," though not all of them were likely connected to the CRM.

Before he was figuratively carried off the show in one, Rick saw a chopper in season eight that he never mentioned to anyone.

Hope and Iris' father, Leo, is working on a cure. In one of his messages to them, he said they "are making progress."

We saw the CRM with undead test subjects in a facility, suggesting they're testing the walkers to search for a cure.

The moment was reminiscent of Dr. Edwin Jenner's work at the CDC on season one as the virologist tried to find an answer to the zombie virus.

Relive the moments: See Joe's note to his daughters 12:06 into "TWDWB" premiere and watch the CRM testing the undead in a post-credits scene to season one, episode four.

When Anne was trading people to the CRM, she would radio a pilot to tell them she either had an "A" or a "B." She classified Negan and Rick as an "A." Father Gabriel was considered a "B" until he backed out on a helicopter journey with Anne. When it seemed he posed a threat and knew too much about the helicopter group, she decided he was an "A."

"'A's and 'B's get a different kind of treatment," "TWD" showrunner Angela Kang told Insider in 2018. "And you saw that both Rick and Gabriel, and also Negan, were going to get zombie bites applied to them."

That last bit fits into a scene from "World Beyond." We now know the CRM has a test subject group of the undead who all appear to be labled "A."

What does it mean to be an "A" or a "B"? It can be inferred that an "A" may be a rabble rouser or someone who cannot be controlled by the CRM. Because they're perceived as a threat, they're made into a test subject. A "B" may be someone who falls more easily in line and works for the CRM's cause as the "last light of the world," as Kublek put it.

Revisit the moment: See the CRM's stash of the undead in a bonus scene at the end of "TWDWB" season one, episode four.

Angela Kang confirmed to Insider in 2018 that Heath was traded by Anne to the CRM. It's why Anne was seen with the RV that Heath was last seen driving on season seven.

"We are hoping to get him back and tell his story," "TWD" creator Robert Kirkman said during a 2018 New York Comic Con panel Insider attended. "There are definitely plans in place there. It's just a matter of making sure that everything can line up because it is somewhat complicated."

Since Kirkman is working on "TWD" movie script, maybe he's trying to find a way to work in Heath.
