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

When interviewing Mercer, Kelly says "it's been a month since former trooper Tyler Davis has been in the hospital under armed guard."

While questioning Mercer, Connie mentions that the woman Tyler took hostage in last week's episode is Mercer's sister.

Max reveals at the end of Sunday's episode that she was actually the mystery woman speaking on the radio to Eugene all along.

This is a huge departure from the comics where Stephanie and Mercer aren't related at all.

Josh McDermitt, who plays Eugene, told Insider it could be "bad" in the future if Eugene realizes they're brother and sister.

When Carol notices a woman subtly cover a bandaged wrist and look away, she's reminded of her own abusive relationship with Ed.

Carol puts the pieces together and, after corroborating her suspicions with a lieutenant, intervenes so Moto can't hurt them anymore.

The list contains AMC employees and "The Walking Dead" crew members, including AMC Networks' executive vice president of public relations Marnie Black, president of AMC Studios Dan McDermott, and visual effects on-set supervisor Tommy Harris.

In season 11, episode two, Mercer told Eugene not to lie to him, saying that he would know if Eugene lied.

At the time, that could've looked like Mercer was just talking a big game. Now that we know Shira was planted as a decoy, Mercer likely knew all about it. Her job was to probably to fill Mercer and Lance Hornsby in if Eugene's story didn't match what he told Mercer during his interrogation.

On the show, it's revealed that "Stephanie" was actually a woman named Shira who was keeping tabs on Eugene.

In the comics, that's not the case. Stephanie is and always was the person on the radio who starts a relationship with Eugene.

At the end of Sunday's episode, a woman named Max (Margot Bingham) claims she's the actual person who was speaking with Eugene via radio. She used the name Stephanie as a cover.

In the comics, there was a person named Maxwell Hawkins who originally greeted Eugene and some of the other survivors to the Commonwealth.

You may haave thought this line was silly, but "TWD" writer Kevin Deiboldt confirmed that series writer David Leslie Johnson-McGoldrick wrote the reference to Bill Murray's "Ghostbusters" character, Dr. Peter Venkman, into Sunday's episode.

Venkman delivers the line near the film's end.
