Elena Gilbert In the show's third season, Elena has a brain hemorrhage which was initially thought to be a concussion, and begins to die.[17] In what was described by the International Business Times as "the moment Vampire Diaries fans have been waiting for", Elena had to choose whether to be driven to Damon or Stefan to say goodbye to. At the time, Klaus was killed, meaning all vampires sprouting from his bloodline also die, which includes Damon and Stefan. She picks to say goodbye to Stefan.[17] However, all these vampires end up surviving when Klaus never really dies. To save her, Doctor Merideth Fell (Torrey DeVitto) fed Elena Damon's blood. Rebekah Mikaelson kills Elena on Wickery Bridge, unaware of the vampire blood in her system. She woke up as a vampire at the end of the season.[17] The Hollywood Reporter interviewed Plec, and described her transition as "monumental changes" which would have Elena in for a "wild ride". Plec said Elena becoming a vampire is "an awakening of a person who is about to go through a lot of changes", and "she is going to evolve as a person and her relationships are going to evolve accordingly".[18] While Stefan was afraid she would hurt someone, Damon thought it was inevitable and wanted to "rip the band-aid off".[18] Plec felt that "She’s, unfortunately, not getting the same advice from the two people she values most in the world. It’s going to make it more difficult for her",[18] while describing the situation as "a whole new Elena and it’s a whole new day. It’s a different dynamic between the three of them especially".[18]
