I think Erza is probably a enchantment maybe the first and that is why Neinhart cannot revive her. Mavis we get her mind back before they take FH but she cannot get out without help. Anyone can see that Zeref still has feelings for Mavis from this chapter. Here is something Zeref could have done to prevent Mavis's pain use Neinhart to bring back the demon Erza killed have her use her cruse to remove Mavis sense of pain
