I don't know if this maybe will come up in The Originals, cause I'm only in Season 1 but I've already seen the death of Elijah and Klaus at the end of season 5 and I asked myself why the sireline of Klaus didn't get killed too? We know that they didn't because in Legacies Season 1 Caroline is in Europe with Josie and Lizzie and Klaus was already dead to that point of time, which means that Caroline should have been dead too, but she wasn't. Is there a reason?
