tbh I just thought about the dichotomy of Rick and Shane and I honestly think it'd be nice if Rick sorta hallucinates Shane? And Shane sorta evaluates Rick's actions and progress. I don't think Shane would agree with Rick keeping the man who beat Glenn to death alive (since that's the only action of Negan's that would affect Shane to a degree), nor would he be fine with the fact he 'couldn't protect' Lori or Carl. Would certainly make for an interesting few scenes.
Of course we can't forget the fact Judith's biological dad is Shane. It'd only make sense for us to get some scenes between the two of them
