Re: I don't think we see Negan until next season, but I think...
Here is a theory. The show usually mirrors the comic but not 100%.
Remember when the Congress lady mentioned her husband? Where is he? What if he was one of those three men she said she banished from the safe home? What if her husband is Negan? Or one of the other two she kicked out?
I couldn't tell if Rick's future fling's husband was at a different house than his wife. No doubt that he and Rick will square off.
The girl may have taken Ricks gun, but she didn't plant the walker. I believe she may be a mole for another group, spying on the inhabitants of the safe zone. I mean she is very young, Carl's age no doubt, and by herself. No way she could have survived out there all by herself.
A major plot twist or two is coming soon. Also, some major characters have been less and less involved. Not much from Abraham and his group, nor from Maggie. Daryl doesn't appear happy at all, but when was he ever besides the time he had with Beth.
And Carol is playing the "I'm just a little woman he he" role for a purpose. Will she save the day again in the future?
