I think by the end of this arc, sunny will find out how to complete slayers soul, thus completing her as a shadow. this in turn will give her the ability to speak and potentially remember her past. Maybe not in full but sunny will now have a servant that can speak and be a "commander".
If i remember correctly, The original vampires basically live as long as they want to. So eno creating arthur make him somewhat and original too?
Im pretty sure Quinn can heal her with his blood? Also, layla can transform and try to heal the damage anyway.
probably wont work because shadow god cursed him with immortality.
