We see the cold open which is the Negan/Rick trailer that was recently released. It is just after Negan whacks out Abe and Glenn. That's been dissected to death, so I'm not going over that now.
Negan throws Rick into the RV and drives the axe into the table. Then Negan tries to drive the RV like a mofo. Negan gets behind the wheel and starts to drive.
Negan mocks Rick about him threatening to kill him. Negan dares him to get that axe and come get him. Rick, being Rick, does just that. Negan confronts him with a machine gun. Rick backs down- wise move.
They take off again, and now Rick starts his dream state, thinking about people in the lineup, and then the lineup folks starting to set up a party/tables back at ASZ.
Negan pulls up to the burning logs on the burning log road and shuts her down. He grabs the axe and opens the door of the RV. Walkers are now around the RV, attracted by the fire/smoke. Negan pops his way clear with Lucille, then tosses the axe on the roof. He tells Rick to go get his axe.
Negan basically tosses Rick out of the RV into the walker fest.
