Arthur Blackthorn theory
I think Arthur Blackthorn is behind the spell that makes Dru forget about Ash all the time.
In her last Q&A, Cassie revealed that:
“We do certainly find out something pretty major Arthur did without anyone knowing”
We know that Arthur suffered at the hands of the faerie and that by his recollection it was because his brother fell into a love spell with a faerie... so what if he, once he got custody of his nephews, put some protective magic in them so that they would never suffer the same? And what if the protecting magic put in Dru is making her forget Ash because due to her interest and connection with him, forgetting him is the only way she is truly "protected"?
While I get where your coming from, if that was the case shouldn't Julian and Emma forget about him as well? If it was a spell placed on all of them, why is Dru the only one effected?
