The Original Plan
Simon had a lot of conflicted feelings about what was going on. A witch was clinging to his descendant and might be their only hope. He was living with the woman he loved again but couldn't tell her that he loved her because she would freak out. The deadline was getting closer and closer and no real solution had been found.
What was he going to do if this failed? He couldn't bear to lose Delia again; he really couldn't.
He loved having her back, even if it was only partial. He wanted them to stay like this for the rest of their lives. A normal lifespan. Together.
That had been the original plan so long ago. That hadn't worked out for them at all. He was still chasing after her five hundred years later, desperately hoping to recreate what had been lost.
