Hi, is it too spoilery to give us an idea about what happened between Klaus and Tatia in Possession?? I've always been so curious. ;)
.....I am kidding....kinda lol
Back in the day when I had started imagining Possession in my head, the Originals were shining in TVD and I have based my idea about Tatia in what Elijah and Klaus had said about Tatia in their dinner with Stefan and Damon in S3.
“And none loved her more than Niklaus.”
“I’d say there was one that loved her at least as much.”
So in Possession, this is the core of that story too.
Generally speaking (references have been made in previous chapters and in the last one) Tatia was Elena’s cousin. Their family had been neutral to both sides -Mikaelsons and Salvatores- but Mikael had eventually managed to create an alliance with them. He had arranged a wedding pact between Tatia and Elijah and later on it was under consideration for Klaus to actually marry Elena. After Tatia’s suicide and Elijah death, however, Elena’s family decided to create a marriage alliance with the Salvatores instead and she was promised to Stefan and eventually married him.
Ironically Elena follows the footsteps of Tatia a lot because of the triangle mess she had found herself in between the two brothers (Which I loathe tbh but I wanted to create similarities between my fanfiction and the show’s canon back then because I wanted to keep some connection with the characters as we have met them in the show since I have fundamentally changed their nature since this is an all human fic. That alone makes it difficult to create an environment where you can keep the characters in character based on how they were introduced in the show. And since in my story Elena is going to be a secondary character anywhere I said what the heck and went with it lol).
The details I can give for now when it comes to my story (without being that spoilery lol) is that Klaus fell in love with Tatia and Mikael found out and this was why he arranged Elijah’s marriage with Tatia. Not just for power or for getting allies but in order to hurt Klaus too. Elijah loved Tatia too. And that triggered a chain of events that led to a lot of death and a shift in the power dynamics of the Mikaelson family giving to Klaus the opportunity to get the upper hand but not without great loss and sacrifice. After that Klaus became far more cruel and swore that he would never allow love to become his greatest weakness again.
