Its not about explaining every bit of information. Its about definitively outlining the fate of a rather important character and events of disappearance having taken place entirely off-screen. That kind of vague information is usually one of two things. Either is poor film-making and communication of details, or its intentional misdirection in order to confuse or mislead the audience. It shouldn't be up to the audience to fill in the details when they are this important. Again I don't buy the idea that they didn't want to show Lori's half eaten body, as they have never been squeamish about showing such things in the past. Within the same episode they showed T-Dog's half-eaten corpse laying there, which was pretty unnecessary as the appropriate conclusion could be drawn from a swarm of walkers consuming him. I also don't buy that they couldn't afford the effect, especially since they spent the money on T-Dog's corpse and a major character death that has a specific and deliberate build up would be something you budget for, not forget about until the last minute. I can excuse bad plot details, inconsistent characters and writing and a vague mythology as part of the show. But when so many details in one instance are left vague pertaining to the remains of a rather important character, whose death will have specific long term effects on several lead characters, I don't buy for a second that its just poor communication. I think its deliberately poor communication. And if I am wrong its a rather glaring omission of detail, requiring a rather large leap in logic.
