During a Halloween party at the school, Vicki loses control and attacks both Jeremy and Elena, forcing Stefan to kill her by staking her through the heart. He swears Elena to secrecy to hide the incident from Matt and Jeremy. Unable to comfort a devastated Jeremy, Elena pleads with Stefan to compel him to forget the events of the night. However, after Stefan tells her he is unsure of its effectiveness, Damon volunteers to "take away his suffering".
