though you find various versions of Ramayana,the inner meaning relating to one's etiquettes remain same.Because it is an 'EPIC',which originally saint Valmiki has written and subsequently many other great poets and religious writers have used the original text to condense or abridge with few examples of their own ,might cause a feeling.Consistency-wise you dont worry,as the consistency resides in understanding the inner meaning and values inserted in the epic rather than just trying to blame ,because you couldnt understand.
