It was in the preview for next weeks ep. I know it doesn't mean she is alive, but... I saw the grave, "C" and flower, but is there a body in the ground. I know it's a lot to go through to dig a hole and then refill it, but still... I guess we will find out.
I have not seen the Talking Dead yet. I thought that might be the case with the walker, but consume and an entire body?? There's usually some bulky remnant's lying about. How do you eat a skull or hips.
