I got the idea from the note sherry left behind and the whole "We always joked you'd show up and save the day with pretzels and beer" that Dwight was possibly planning on showing up and running off when her when they showed him leaving a bag of pretzels and beer in the house.
I don't know how i feel about Negan. I don't know if he's really well written, Jeffrey Morgan is a really good actor, or it's a combination of the both. I want to hate the guy, I mean he's clearly evil, but, the way he acts in the show I honestly get the vibe that Negan thinks, in his head, that he's doing the right thing and his actions are justified.
