The Walking Dead Season 6 Finale: 7 Things You Might Have Missed In Episode 16
4. "That's Just The Way It Is."
Just in case you needed any more pointers to the fact that Negan was going to wipe out a character by the end of the episode, we learned about the Saviours' methods very early in the finale with a sharp warning:
"Give us all your stuff. We'll probably have to kill one of you, that's just the way it is, but then we can start moving forward on business. All you have to do is listen."
It's essentially the entire purpose of Negan's speech, and the idea of killing a group member to assert authority doesn't sound like a new way of operating for the Saviours. It also offers a teaser for Season 7, suggesting that Rick's group are going to have to work for the Saviours if they are to survive.
