i once read a theory about leslie still being alive even after he got shipped out . like what happened to norman . it was said that he might be zazie since we didnt getto see his face yet and theywere both playing with butterflies sometimes !
alot of fans wishes for him tobe alive and have a faithful reunionwith isabella ;)
they also say that zazie trying to talk is actually him trying to sing (leslie's melody)
here is the link for the discussion of that theory CLICK HERE
