Thank goodness loud mouthed exposition Merle filled Rick in on goings on.
Ghost of Christmas Past came to see Rick. All it takes is a baby crying to trigger his muh-muh-muh-mad-madness...
I think we will see Two spin-offs:
Already mentioned, The Walking Dixons...sounds cool, until we learn that half the episodes are flashbacks to their childhood with Donna Dixon as their mother.
The Michonne Ranger...she's out there on her own...alone. Most episodes have no dialouge. They later add a native american sidekick, Grunto, who is a zombie, of course.
