We found a promo of Mckenna for episode 15 of TVD. Mckenna played the role of Young Caroline on CW’s The Vampire Diaries. She appeared in episodes 14 and 15 of season 6. Here are some behind the scenes photos from the episodes. *Fun fact- Mckenna learned to ride a bicycle without training wheels for The Vampire Diaries. In the episodes, her mother is teaching her and in real life Mckenna learned  the night before she flew out to Georgia to shoot the episodes. She was very nervous, but determined to do it because she really wanted the part!
