Hyperfixation Cupboard

Owen will die smug, bitter, and self-righteous; feeling that his death only serves to prove that he was right all along. Either a human kills him and humans were the vial filth he believed them to be; or a vampire will kill him and it's only more proof he never belonged with them, because they've betrayed him. Either way, Owen will have proved himself right.

Or, Owen's mind is changed/he comes to his senses only moments before he dies, when it's too late (similar to Maze!Owen). Something like vision in death of Louis telling him that's he's disappointed, or turning his back to Owen, a manifestation of what Owen has subconsciously known the whole time and has been in denial of; that Louis would be horrified of what Owen has become. Owen realizes as the stake is being driven in that he's manufactured his own downfall where he didn't need to. He could have gone back to the village with Legs, he could have found a family in the Coven, but instead he chose to burn every connection and relationship in the throughs of revenge. Now Louis' gift and legacy dies with him, wasted on the pain, suffering, and hatred Louis was trying to cure in the first place.

Owen's story is very much one of grief and moving on, but it's a story about someone who refuses to move on. Someone who holds on to the cruelty, pain, and bitterness, and takes it out on everyone who attempts to reach them. Eventually, people stop reaching out. Eventually, you whither away and self-destruct alone. As a character, I think the lesson Owen needs to learn is that he needs to move on, for his own sake. He needs to live in spite of the pain and hardships of his past. He doesn't need to forget, and he doesn't need for forgive, but he needs to move forward for himself.

I think it's a lesson Louis tried to teach him, in a way. Louis turned him, gave him kindness and understanding and an eternity to find happiness beyond the town's cruelty. Louis' gift was the chance to move on and find peace, and Owen has tragically turned that gift into the weapon he uses to exact his revenge over and over and over. And it's going to be the weapon that's turned back on him when he dies.
