When Does Caroline Become a Vampire?

The Exact Episode & Moment

  • Caroline officially becomes a vampire in Season 2, Episode 2 – “Brave New World.”
  • Her transition begins after she is killed in the hospital with Damon’s blood in her system , which Katherine had taken advantage of. Katherine smothers her with a pillow at the end of Season 2, Episode 1 (“The Return”), triggering the transition.
  • In “Brave New World,” Caroline wakes up, goes through the confusion and bloodlust of transition, feeds on human blood, and that’s when she fully turns into a vampire.

In simple terms:
She dies at the end of S2E1, completes her transition and is officially a vampire in S2E2, “Brave New World.”

Who Turns Caroline Into a Vampire?

So: Damon’s blood + Katherine’s attack = Caroline becomes a vampire.
