First of all, how the Hell could such dumb couple survive this long? It's a bit of cop out to just drop them into this Ep. then kill them fast just to show how cold Carol has become.

Obviously Carol will be back (in fact what is to stop her showing up at the prison to get the girls right away). Given her comic book history (as described by Cannoli above) I thought she was going to end the episode by killing herself.

How will rich explain where she went? Will he say she died? Will Tyreese go after her?
