10 details you may have missed on Sunday's episode of 'The Walking Dead'

On "TWD" season premiere, Maggie slipped from a subway car and fell into a tunnel filled with walkers. How did Maggie escape unscathed?

She took a page out of her late husband's book.

When Glenn faced a similar impossible escape at the end of season six, episode three, fans had to wait four agonizing episodes (one month in TV time) to learn that Glenn shimmied under a dumpster in order to survive.

We're sure Glenn likely recounted this story of survival to Maggie. Whether intentionally or not, she found herself in a similar situation where she needed to pull herself under the subway cars to escape the dead before making her way inside the car.

In a message on aftershow "Talking Dead," executive producer Denise Huth said "it's possible" that Maggie may have learned morse code from the chart that appeared in Michonne and Rick's Alexandria home on season seven.

According to "Talking Dead," two ads that can be seen in the subway cars are "Duane Jones Whiskey" and Gorbelli Foods Company."

The former was the brand of whiskey that Aaron and Father Gabriel stole from Mays on the season 10 bonus episodes. The latter is the name of the company where Tara's father worked before the apocalypse.

That's a deep cut.

The Triumph of Death showcases a skeleton army destroying everything in their path. (You can view it here.)

Bosch's The Garden of Earthly Delights is a triptych (view it here). The image on Sunday's "TWD" most likely references the right most panel of the oil painting, which depicts Hell through a series of illustrations depicting sin, temptation, and greed all leading to the destruction of man by his own devices.

The mural which Daryl sees seems to be a combination of themes from both.

Man is at war with himself instead of his true enemy, the undead. The petty war between humans ultimately leads to their destruction by the vast horde of walkers who they should be rallying together against.

On a special featurette after the episode on AMC+, showrunner Angela Kang the mural told the story of what happened in the subway tunnels.

"The backstory of it is that there was this massive class struggle that happened. Poeple wound up murdered and stuffed in bags," Kang said.

"Talking Dead" points out that "people are fighting each other and not the walkers surrounding them" in every section of the mural. It's also likely the mural symbolizes the conflict playing out between Negan and Maggie's group in the subway car as the dead similarly surround them.

The mural Daryl sees may foreshadow an impending conflict between Alexandria and the Commonwealth, one which ultimately may be unnecessary if it meant they were stronger as one. Kang hinted that it speaks to a class struggle that we'll see on the show.

The message reads, "Dear Dad, You always said if you don't come back in a week to move on. Mom didn't listen and went looking. It's been 3 weeks, so we're going next. I'll watch Jesse and turn on the radio every day at 10. See you both soon. Love, Tom and Jesse."

Rick similarly told Morgan on the show's first episode that he'd turn on his radio every morning, but at dawn, to check in on him and Duane. He did it for a while, but then the group was moved farther and farther from Rick's hometown.

Kang confirmed on AMC+ that the white rabbit that Daryl sees in the photograph with the children is the same stuffed bunny that was seen in the season 11 premiere in the tunnels.

This one might be a little bit of a stretch, but both Gage and the Governor delivered haunting deliveries of the word.

On Sunday's episode Gage said it when Maggie decided they didn't have time to save the teen who was trapped in a subway car with walkers. Instead, they watched him get torn apart by the dead.

On season four, episode eight, the Governor said the word quietly after Rick Grimes suggested they could all live at the prison together instead of fighting over the building.

As we know, Eugene is quite the skilled liar. He's such a good liar that he convinced Abraham and Rosita to take him to Washington, D.C. because he claimed to know what started the zombie outbreak.

"When Mercer called him a bad liar, it was definitely one of those situations like, 'Hold my beer,'" Josh McDermitt, who plays Eugene, said on "Talking Dead." "Eugene's super power is lying. He could either lie to get something you want and be nefarious about it or you can lie to survive and that's really where Eugene thrives is when he's just trying to survive and keep other people safe."

McDermitt said Eugene was a bit offended when Mercer called him out.

"He did not like that. So he made Mercer look like an idiot," McDermitt said of Eugene subsequently putting on an act and lying circles around him.

Though he added bits of truth about Stephanie, he continued to lie about coming from a large community.

That wasn't a lie.

Eugene did that on season 10, episode 11 during a montage sequence as his group prepared for battle against Alpha and the Whisperers.

We noted last week that Yumiko's story arc is a remix of Michonne's from the comic when she finds her long lost daughter, Elodie, at the Commonwealth.

In the comics, Elodie's a baker.

The show is making Tomi (Yumiko's brother) into a surgeon. We can't help but wonder if there's a reason for that and if that reason has to do with Ezekiel who could probably use a good surgeon right about now.

Josh McDermitt, who plays Eugene, confirmed to Insider in 2019 that Margot Bingham voiced Stephanie on the radio. The woman who presented herself as Stephanie at the end of Sunday's episode isn't Bingham.

The role likely wasn't recast as Deadline previously reported that Bingham joined "TWD" for its 11th season.

What's going on?

The Commonwealth may be further testing Eugene and his friends by sending in a decoy to see if they were lying to them about coming from a large community. That's not good news for Eugene who has been lying to everyone but Stephanie.

Mercer, the leader of the Commonwealth army, warned Eugene that if he lied to him, he'd know. We're wondering if this is what Mercer meant. If so, Eugene may be in trouble.
