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

"The Walking Dead" logo is slowly decaying more and more this season.

"TWD" logo has started to decay after the season 10 finale.

But on Sunday's episode, it noticeable started to crumble even more. It may continue to decay as the season continues.

The location used to film the dairy farm has been used on the show before.

According to after-show, "Talking Dead," the location is also where Rick (Andrew Lincoln) and Anne/Jadis (Pollyanna McIntosh) took off in a CRM helicopter on season nine, episode five, "What Comes After."

Anne will return to "TWD" universe on season two of "The Walking Dead: World Beyond" when it airs this fall on AMC starting in October.

Greg Nicotero was the walker who bit Agatha's arm.

"So Greg Nicotero decided that since this was the last season he wanted to be in all places. He wanted to be the walker that killed me," Laurie Fortier, who played Agatha on "TWD," told Insider recently of how it was "an honor" to be killed by Nicotero.

"He's such a humble guy," Fortier added. "He still is so excited about what he's doing after all these years. It's just so refreshing to see that and to work with somebody that just loves their job so much."

Fortier shared the above photo with Insider. You can read more about how Agatha's death scene came together on Sunday's episode here.

Nicotero's cameo on Sunday's episode nearly mirrors his first time as a member of the undead on the show.

On season one, episode four, "Vatos," Nicotero was the walker who bit Andrea's sister Amy as she exited an RV camper.

On Sunday's episode, Nicotero similarly grabs Agatha before leading to her demise. Both times, he effectively latches onto the women before biting their flesh.

It's a nice full-circle moment for the show's final season.

Agatha and Duncan were partners.

"Duncan is my partner," Fortier told Insider. "In the script, it was very much Duncan and Agatha are together. I don't know if you picked up on that. There's just so many other storylines going on."

Fortier added that when Duncan died, it was easier for her to die later in the episode.

"When he dies, then it's kind of like, "I have nothing else to live for,'" Fortier said. "So of course it would make sense in that moment that I would sacrifice myself so Maggie can get away."

Negan warns Maggie that they can't be on any roads, which feels like a direct callback to the season six finale when his character was introduced on the show.

On Sunday's episode, Negan suggests to Maggie and Alden that they stay off the roads to avoid the Reapers who attacked, and separated their group.

"We can't be on a road," Negan warns Maggie and Alden, before adding, "We can't be on any roads that they could use."

Negan sounds like he's speaking from experience, not as someone who had to do the running, but as the former leader of the Saviors who blocked off just about every single access road to Rick's group on the season six finale before making his entrance onto "TWD."

The episode's title, "Hunted," is exactly what Negan and his Saviors did to Rick and Maggie's group. They menacingly hunted them down (for killing Negan's men) until they captured and lined them up for Negan.

The end of Sunday's episode mirrors a harrowing moment for Maggie.

After Negan kills a walker with a crowbar, he looks at Maggie. The camera shifts to focus on the bloodied crowbar. Instead of Negan's face, it's the object of Maggie's focus.

The bloodied weapon triggers a painful memory for Maggie. Though we don't see it on screen, all Maggie sees is Negan's bloody baseball bat after he viciously killed Glenn on the show's season seven premiere.

"As soon as he's done something that's a little redeeming, we see the blood dripping from the crowbar and can't help but think of the blood dripping from the bat and what he did, and who he is, and how that will never change," Lauren Cohan said on "Talking Dead."

No matter any goodwill Negan has seemed to make with Maggie, it's an instant reminder of that dark day from her past.
