This was just a cabin before the apocalypse.
Lydia wakes up tied to a chair in a small cabin. She struggles to get out of her restraints.
Lydia starts to break free from her restraints. Lydia finally breaks free of her restraints and rushes to the door. When she opens it, however, she only finds a foggy clearing.
Negan goes to the cabin where he imprisoned Lydia earlier so he could free her. Upon entering, however, he finds her missing and is greeted with a punch to the face from Daryl, who holds Negan at crossbow-point. Daryl interrogates Negan about Alpha's location, but when the latter reveals that he killed Alpha, Daryl doesn't believe him. As proof, Negan presents Alpha's mask, but Daryl isn't convinced. Negan claims that the only reason he joined the Whisperers was so he could kill Alpha, and rhetorically asks Daryl why he thinks his "girlfriend" let Negan out of his cell.
