^Interesting. Maybe we'll find out at the mid-season hiatus. Carol going after her sort of makes sense though. It would explain her absence.
If that conjecture is right, Carl's disposition would make a little more sense inasmuch as he didn't actually shoot her.
Or, Carl did shoot her, but the bullett just grazed her. Then Carol would have to sew up a field cesarean and then get Lori out of that room.
Seems impossible, doesn't it?
