Rebekah (Claire Holt) is the only Mikaelson sister and is one of the Original vampires. She first appears in The Vampire Diaries when we learn what the Originals are, and then makes the jump to The Originals. She is called back to Mystic Falls after Hope has become the Tribrid and has turned off her humanity after killing the love of her life. Sadly Rebekah doesn't have what it takes for Hope to flip her humanity back on, but it was great to see Rebekah after four years.
