At San Diego Comic-Con 2018, AMC showed a new teaser for The Walking Dead Season 9. It's a short one but provides plenty of setup for the next stage in Rick and the gang's fight for survival. The trailer begins with Merle traveling with Maggie.

The real meat of the trailer is in a bit of dialogue delivered by Michonne. "We need to start talking about making some rules," she says. "An agreement between all the communities. Like, 'This is how we treat each other. And this is what happens when we don't.'" A sign shows directions to HQ, Oceanside, Alexandria, Sanctuary, and Toledo, and although the communities are living close together, it seems this truce is uneasy.
