Welcome to Alexandria! Big changes are happening on “The Walking Dead.” The rough days on the road, sleeping in the woods and hunting rodents are long gone (well, old habits appear to die hard for Daryl). In episode 12, “Remember,” the survivors entered the Alexandria Safe-Zone. Check out everything viewers learned about Rick (Andrew Lincoln) and the gang’s new home:

1. What Is Alexandria? -- Prior to the zombie apocalypse, the Alexandria Safe-Zone was a fully sustainable community. It has running water, electricity and more. Homes were being sold for more than $800,000.

2. Meet DeAnna Monroe -- DeAnna (Tovah Feldshuh) was a former congresswoman from Ohio. When the zombie apocalypse started she was heading back to Ohio with her family to help her people. The military directed her family to Alexandria, and they have been there ever since. She knows the whole history of the safe haven and “interviews” newcomers. She also assigns jobs to everyone who enters.

3. The Wall -- Alexandria didn’t always have a wall around it. DeAnna’s husband was a professor of architecture. He was the one who got the first plates up. When more people arrived they were able to finish the wall.

4. The People -- According to DeAnna, most of the people living in Alexandria have been there from the start, which means they haven’t had to live out in the “real world.” Rick’s group is the first batch of survivors they have “considered” allowing in a long time. “We need people who have lived out there,” DeAnna explained.

5. Exile -- Before Rick’s crew arrived, DeAnna was forced to exile three men who “didn’t work out.”

6. Amenities -- Alexandria has a wide-range of amenities like a weapons locker, food pantry and school.

7. Casa de Rick -- Rick’s group was gifted with two homes. Needless to say, they were suspicious. They decided to stay together in one home, but by the end of the episode agreed they could split up into the two houses.

8. Meet Jessie -- Jessie is a resident who works in the pantry. She has two sons, the oldest Carl’s age. Prior to the apocalypse she was a hair stylist. After Rick showered and shaved his beard, she trimmed his hair.

9. Get to Work -- Everyone has a job in Alexandria. “Looks like the communists won after all,” DeAnna joked. Glenn (Steven Yeun), Tara (Alanna Masterson) and Noah (Tyler James Williams) were placed on the supply run squad. Carol (Melissa McBride) lied and said she was the group’s “den mother” while out in the world. She became a cook for the elderly. At the end of the episode, DeAnna asked Rick and Michonne (Danai Gurira) to be the Alexandria “constable.” Daryl (Norman Reedus) was the only one left without a job because DeAnna was having a hard time figuring him out.

10. Natalie and Bob Miller -- Natalie and Bob are an elderly couple who had five kids and 12 grandkids prior to the zombie apocalypse. They’re excited to have baby Judith around because it has been a “long time since everyone’s seen a baby.”

11. Enid -- Enid, like Carl (Chandler Riggs), is a recent Alexandria transplant. She’s quiet, has an attitude, likes to sneak over the walls and doesn’t seem to like Carl.

12. Ron -- Ron is Jessie’s son. He’s Carl’s age.

13. Meet Aiden -- Aiden is DeAnna’s son. He was part of the ROTC before the zombie apocalypse hit and now he’s the leader of supply runs. He likes to run things with a strict “system” and requires all people under his command to follow his rules. Unfortunately things didn’t work out for Glenn, Tara and Noah. Aiden explained that they lost four people last month because they didn’t “follow the system.” Aiden and his second in command, Nick (who was working at the gate when Rick’s crew entered), tied up one of the walkers that killed their group members. That didn’t fly for Glenn -- especially when that walker got loose and almost attacked Tara. Aiden fired them from the job, and a fight broke out when they got back to Alexandria.

14. Blender Gun -- The people of Alexandria might have eyes on the outside -- or there are other humans lurking in the area. The gun that Rick hid in the blender was gone when he returned to the abandoned house.

The group (except for Daryl) seems to be trying to make it work in Alexandria in episode 12 of “The Walking Dead.” However not all is as it seems.

“If they can’t make it, then we’ll just take this place,” Rick tells Carol and Daryl in the final moments.
