In the video: Stephenie Meyer discusses that she never planned to write a book. And yeah, the late 90's early 00's TV special effects were kind of campy and lame a lot of the time, but the stories told were what makes this one of the most well-loved and memorable TV shows of all time. With each season, her life just got worse and worse and the show only got darker and darker, but Buffy and (most of) her crew always pulled through in the end.
She was then exiled to England, where she quickly assimilated into her new culture and met two nobleman brothers, Niklaus and Elijah Mikaelson.
At first, she was attracted to both men, but in time, she eventually learned that she was a Petrova doppelgänger and that Klaus was planning on using her as a sacrifice in order to break the curse that bound his werewolf side.
After failing to induce Klaus' forgiveness by securing the cure and handing it over to Elijah in Season Four, Katherine managed to draw Klaus away from Mystic Falls by revealing to him in a letter that a witch in New Orleans named Jane-Anne Deveraux was plotting against him.
Once Klaus and Elijah officially returned to New Orleans, Katherine moved back to Mystic Falls, confident that the Mikaelsons would be too preoccupied with their complications there to pay any attention to her.
With this list of vampire slayers, you'll always know who to call if you find yourself surrounded by bloodsuckers.
I'm not sure when it happened, but at some point in the last few years all of the vampires in fiction - whether it be movies, TV, or comics - became giant vaginas.
In the late 19th century, she traveled to Mystic Falls, where she met Stefan and Damon Salvatore, whose family hosted her at the Salvatore Estate.
She later fell in love with both brothers, and subsequently fed them her blood, resulting in their eventual transitions into vampires after they were killed by their father in early autumn of 1864.
Klaus was so infuriated with Katherine's sabotage, that she was forced to live on the run for over 500 years as he hunted her down.
Her activities during her first centuries as a vampire are unknown, but at some point between the 15th and 19th centuries, she took on the alias "Katherine Pierce" (an anglicized version of her birth name) and eventually met and befriended Pearl, Anna, and Emily Bennett.
She was the main antagonist of Season One (mostly off-screen through John Gilbert's and Isobel's actions, as both were working for her in order to kill off the tomb vampires), and one of the main antagonists of Season Two, the second half of Season Four and the first half of Season Five. Katherine can be considered the main antagonist of the series overall due being a major antagonist in the first, second, fourth, fifth and eight seasons and all the antagonists that were a result of her actions.
