So look it has to be said.

That was complete and utter bullshit. That episode was 90 minutes of god awful filler. There were 2 developments, Morgan and Carol meet another group it looks like.

And someone meets Lucille.

The fact that the show-runner and writers decided to end the season like that, without a clear answer as to who it was that died is just cowardice. They literally just wasted a 16 episode season to introduce 1 new character. 16 episodes for 1 scene, a scene that people have been waiting for for a long time, and they chickened out.
