The Vampire Diaries: 10 Worst Things Bonnie Has Ever Done

1. Used Expression Magic

Desperate to regain her magic after losing her powers for a time, Bonnie turned to Expression, a form of magic Professor Shane from Whitmore College introduced her to. Despite her grandmother's warnings from beyond and the clear damage it did to her mind, Bonnie continued practicing Expression to help her friends.

They didn't want her succumbing to a dark path on their behalf, but Bonnie didn't just do it for them. She wanted to stop feeling powerless and be a witch again. Shane used her but Bonnie went against her better judgment.
