"The Walking Dead" left us wondering after the mid-season finale episode of season 4. Fans will have to wait until February 9, 2014 when the second-half of the season premieres. Recently, Robert Kirkman shared some second-half season 4 teasers with TV Guide.

Robert mentioned:

1. "Carol will definitely return before the end of the season." We saw Carol in episode 4, "Indifference." After the said episode, Carol did not came back to the show. Rick was to blame because she had gone to the car with him and never returned.

2. "The Sanctuary, which was discussed in that radio message, will come into play." It is possible that Carol turned on the radio and got to know about The Sanctuary. Will the group reunite at The Sanctuary? Will The Sanctuary connect the characters?

3. "Via flashbacks, there will be glimpses into the lives of our favorite characters, likely including Michonne."

It will be interesting to know the past of Michonne and other characters.

Talking about Michonne, she hasn't disclosed much about her life and her past. Remember when Beth handed over baby Judith to Michonne, she displayed a very different kind of emotion. Michonne started to cry while holding Judith in her arms. Do you think Michonne had a baby or babies in the past?

Who else will get their share of flashbacks? It will be good to know Tyreese, Bob Stookey and Sasha's past.

These teasers from Robert Kirkman like The Sanctuary, Carol Peletier's past, Michonne and other's flashbacks left us wondering what direction will the story flow towards?

"The Walking Dead" will return and answer all the burning questions on February 9 with the second-half of season 4.
