it is true Lucas hinted on that in the previous chapters.
Lucas words were:
"She was killed the first, then was given a second chance but gave up, what will happen now that she's finally back."
and they been (hinting) talking about that in the recent chapters before she made the final decision of using the world tree branch to remove the curse from claude. guess you should go back to the earlier chapters when claude lost his memory. Lucas hinted it there a lotta times.
it was hinted. but mots of the theories are confirmed when lucas said the words:
"She was killed the first, then was given a second chance but gave up, what will happen now that she's finally back."
this was in the previous chapters I think around the time Claude lost his memories then got into a coma

What makes this even more amazing is while athy might not be her daughter in mind but in flesh...she is still getting that love an reassurance a mother would to their child which she never experienced....n it breaks my heart but fills me with joy
