ive been listening to some podcasts that really go into depth into different theories, its pretty interesting. libby will still be in flashbacks even though shes dead, so apparently she fits into more stories than just desmonds i guess. apparently there is a theory she was some sort of chronic liar. we know she must be mental fucked someway, she was in the ward with hurley and then claimed to everyone she was a clinical psychologist. i think that in the pre island life she was pretty evil. well see. KoH, foot theories?
