"The Walking Dead" Season 6 fans were surprised to find out that Enid (Katelyn Nacon) could be a spy tasked to watch over the people of Alexandria.

According to Design & Trend, there are at least three reasons why Enid could be working with the wolves even though this hasn't been confirmed yet on the show.

One of the reasons mentioned by the publication was Enid's reluctance to go inside the gate of Alexandria. In the flashback scene from Sunday's episode, Enid was featured standing right in front of the community's gate, and she was hesitant on whether or not she should move forward.

Another reason why Enid could be a spy is because of the fact that she has the keys to all the doors of the walled community.

"During the attack of The Wolves, it was revealed that Enid had a set of keys that could seemingly open every door in the community. There was no indication that Enid had been keeping those keys before, so it was very suspicious that she was in possession of those during the human invasion," the publication noted.

Additionally, there was also one scene from "The Walking Dead" where Enid referred to The Wolves as "we."

While speaking with Carl (Chandler Riggs), Enid said, "There are too many blind spots. That's how we were able..."

Moreover, Enid was surprisingly calm during the recent attack of The Wolves on the show. At that time, it seemed that the character was certain that she wouldn't be attacked by her fellow wolves, and she wasn't.

Lastly, Enid's departure from Alexandria happened around the same time that The Wolves retreated.

In other news, "The Walking Dead" Season 6 will see the survival of Glenn (Steven Yuen). According to The Hollywood Reporter, the actor's contract was recently renewed by AMC, so it's highly likely that fans will continue to see Glenn throughout the upcoming seasons.
