We've already discussed this and so did the director, that wasn't Lori, it was the walker that supposedly ate her
A walker could have easily taken a chunk of someone's hair and they got away, not saying this is true but it's not 100% sure that he ate her dammit, regardless of what the talking dead says, they're not gonna say exactly what happened, WHERE ARE HER FUCKING BONES unless carol found her and took her body so they could bury her properly...
Just waiting til Sunday lol
