The Walking Dead doesn’t return until October 11, but the recently released trailer for season six makes us uncharacteristically wish for summer to hurry up and be over.

The trailer shows an increasingly unhinged Rick Grimes struggling to maintain some sort of order and control in the Alexandria safe zone, while those closest to him begin to question whether it’s safe to let him continue being in charge.

It’s a super intense look at the drama to come, including hordes of walkers, Darryl Dixon being held hostage, and probably our first look at Heath (a favorite character from the comics) at the 2:39 mark.
