15 details you may have missed in the 'Walking Dead' season 9 trailer

Let's start out with the most obvious. Rick said he wanted to build a new world and in order to do that, he knew he would have to put Negan away. When Rick decided to spare Negan's life at the end of season eight, it looks like he put him in a new jailed cell where he sometimes comes to visit.

If you look closely, Negan has a very long beard which matches the one Jeffrey Dean Morgan has been sporting in public. Comic fans probably weren't surprised to see this since this is exactly how Negan's storyline goes down in the comics. 

Lauren Cohan's character has been pregnant since season six without really showing. Three seasons later, her child is finally here.

In case you think that might be another baby, the "Walking Dead" Twitter account confirmed it's Maggie's baby.

Doctor Carson told Gabriel if he didn't treat his infection that he could lose his sight. After a season of dealing with blurred vision, it looks like Father Gabriel is up and about but at the cost of one of his eyes.

You can spot her working with Enid and Saddiq briefly in the trailer with a new hairstyle.

In another shot of the trailer, we see Anne walking through a camp with Tara, who appears to be her new BFF.

Anne is seen communicating with a helicopter. Is that the same one she was trying to gain the attention of in season eight? 

Is Anne going to ditch Rick's gang for another group? Do they have something to do with this new territory in Toledo? Actress Pollyanna McIntosh told INSIDER she knew the helicopter was coming for awhile and her character seems to know more about it than she's been letting on. 

"This seems to be some other situation out there. Is it an extension of the Heapster community? Is it another community? Is it a single person? Is it a group? I don't wanna give too much away," McIntosh said.

If you look closely, the helicopter has the same three circles that were on the lid of the applesauce Anne ate at the end of season eight. You can read our theories on what the mysterious helicopter is all about here.

Father Gabriel spots a drawing signed by Anne. Presumably, it's a self-portrait. Anne was big on sculpting and painting from the time we saw her with the scavengers. It looks like she's keeping up with that hobby.

It's not just Ezekiel's guard Jerry who has found love in the apocalypse. Look closely in the background here and you can see Carol and Ezekiel getting cozy.

There is some turmoil brewing within the Saviors who are stil loyal to Negan and those who just want to move on.

Or at least she's working with him, Maggie, Michonne, and more here. Cyndie is supposed to be the leader of the Oceanside community now that her grandmother's gone.

Those look like Rick's (Andrew Lincoln) iconic cowboy boots that have blood on them and he's limping. Reddit user Afrothunderzx shared a great GIF of the moment on "The Walking Dead" subreddit for you to rewatch.

What happened to Rick and is this a hint at how his character could leave the show?

Does Daryl injure his pseudo-brother?

In the comics, Maggie goes kind of dark and winds up killing Gregory to set an example. May we see that play out again on season nine? It sure looks that way.

According to The Hollywood Reporter, Fogler will play Luke, a survivor of a new group. 

Michonne is seen near the end of the trailer lifting up the bat.

Rosita and a man are seen covering themselves in mud to hide from a bunch of walkers. If you listen closely, it may sound like you hear some of them whispering. That's the point. 

The next big villains in the characters are called the Whisperers, a bunch of survivors who cover themselves in the skin of the undead. During the Comic-Con panel, Robert Kirkman confirmed Samantha Morton will play the group's leader, Alpha.

The difference is that it's two characters named Marco and Ken who hide from the Whisperer horde in the comics.

It says the Commonwealth. That's the name of a big community that was recently introduced in the comics that is run out of Ohio. While Rick is walking around the camp, there are a few signs posted showing the direction of different camps. Among them is one that says Toledo. Toledo ... Ohio?
