While Stefan struggles to come to terms with his past, both he and Damon reveal parts of their history to Elena, until she finally learns the truth about how they became vampires. Pearl has an ugly confrontation with Jonathan Gilbert. Damon and Alaric try to find a mysterious invention before Jonathan does. The friendship and flirtation between Jeremy and Anna continues to grow.
Isobel returns to town and stuns Alaric with her attitude and her demands that he arrange a meeting with Elena. When mother and daughter finally meet, Isobel refuses to answer most of Elena’s questions, but reveals that she will stop at nothing to find the mysterious invention Johnathan Gilbert has been searching for. Isobel’s dangerous actions lead Stefan, Damon and Bonnie (ABOUT TIME!) to step in and help Elena deal with the situation.
