What we know:
- Lori died during childbirth.
- Carl claims to have killed Walker-Lori, but it was done off-screen if it ever happened.
- Rick went to recover the body but only found a walker that looked like it had very recently fed.
So, what happened to the body? Has it really been totally consumed, or is Lori a walker now?
No official answer has ever been given, but there was a deleted scene fueling the Walker-Lori theory.
The final version showed Rick talking to what appears to be a vision of Lori. The full version pulls back to show Lori as a walker.
But Walker-Lori appears to be wearing the white dress Live-Lori wears in the vision (it's cropped out of frame, but the straps are slightly visible), and neither Lori can be seen in the wide shot. Lori was not wearing the dress when she died and the white dress is likely just symbolic.
So is Lori really a walker out there somewhere? It's doubtfulThe other possibility is that she's not a walker at all. She's survived the c-section and is living/hiding somewhere. This would explain the lack of remains or clothes.
Both the Walker-Lori and Survivor-Lori theories are extremely unlikely, but there iswithout a body or remains of any sort, we have no conclusive evidence of Lori's fate.
