When The Vampire Diaries' Elijah was introduced in Season 2, he wasn't supposed to stick around long. More than a year after his arrival the character remains one of the most popular in the show's history.
"In the beginning I was a very old vampire who was going to live like two episodes," Daniel Gillies explains to TVGuide.com. "They didn't know I was going to be a brother, I [just] was a henchman." But Elijah has transformed from being terrifyingly powerful in his knowledge and skills, to a still powerful vampire, but one with a distinct moral compass and compassion for Elena who Gillies calls a warrior.
