My suggestion is perhaps refer to heartfillia child?
If you are talking about when zeref was speaking about wendy, then that child might be edo-jellal.
I think zeref meant his son
but wendy and zeref's son never met , or did they ?? o:O
we should sue him or something isn't it illegal to leave us this way! No? well it should be! damn so unfair!
Who is THAT CHILD zerf is talking about? O.o Any suggestions ?
ARRGH again we need to wait a week for the next chapter with such cliffhangers it's ike torture :OOO （/TДT)/
