The Hunters form a group called the Five. I used to be engaged to one of them. They're the ones who created the daggers, a religious cult with the aim of killing my family and ending the vampire race. I'm actually a little bit flattered. Anyway. They were also connected to the first immortal, Silas, and that Cure. Which yes, I wanted for myself. I wanted out of all of this. But I had known about the Cure since 1114. I'd gone without it before, I would again. Klaus wanted it so he could destroy it, Kol wanted everyone the fuck away from Silas and Elijah was off somewhere at the time, no idea where.
Of course it was because of Klaus. They didn't know then about the bloodlines, didn't know that killing him would also kill the Salvatores, Caroline, Tyler Lockwood, and now Elena. It's why he's safe now. But ask Elena some time, did she knew then which bloodline Lee's from. Anyway, yeah, she wanted Klaus dead, wanted all of us dead.
There are reasons Klaus is the way he is. Right back to when we were children and Mikael would beat him bloody on a regular basis. He would hit all of us, but Klaus had it the worst. And he's now a narcissistic control freak with abandonment issues. As for why I keep going back, he's my brother. And there are moments, just sometimes, when there are glimpses of the boy he used to be. A sweet boy who looked after his little sister when the storms got too scary, who put frogs in Finn's bed when he was being annoying, who taught Kol to ride a horse, who idolized Elijah. There are moments when he's good, Sam. And I can't walk away from that, even when he hurts me. Besides, maybe we all get the pain we deserve anyway.
