I watched possession(1981) and I don't think it was a good idea(and I'm dragging Ashita no Nadja into this because the show has me in a chokehold)

Okay, I'm not sure how to talk about possession. It's a heavy movie with a lot of symbolism used to show the themes of religion and divorce. I don't feel qualified to talk about it, so instead, I'm just going to talk about how interesting it would be if someone made fanfic about the Harcourt family, but instead of Amelia dying, it plays out like the events of possession, of course with a few tweaks here and there, but just imagine Amelia and the Marquess arguing so much that it becomes a screaming match and the Harcourt twins( who are 7-8 during this time) pretending like they hear nothing. Pretending like they don't hear their mother screaming about how much their father disgusts her while Keith, in an attempt to distract Francis, takes him outside to play, which happens a lot more often now.

Amelia disappears for days at a time for who knows what reason, and her behavior becomes more erratic. She also becomes more distant from the twins, bringing more questions nobody can answer. People start dying the more they try to uncover what is going on with Amelia, and their father increasingly becomes more obsessive with finding her and keeping their marriage intact. Going as far as to harm Amilia when she slaps him.

Everybody in the mansion is wary of them, and the twins are constantly left in the care of Amy, a housemaid who looks a lot like Amilia, almost to an uncanny degree. 

When all is said and done, the twins are left in Amy's care in a house far from the mansion. Amila and her husband are found dead on the steps of a tower, and a man looking suspiciously like their Father comes to their doorstep.

The twins beg her not to open the door, but she does anyway, excusing their pleas as nothing more.

So they go outside and drown themselves in a pond so they don't have to see the thing that happened to their parents repeat with Amy and the creature.

I guess Nadja won't be having her love tringle this time around.
