Beware, Bonnie: The Vampire Diaries is set to introduce a father/son duo who will take a special interest in this Mystic Falls witch.

On episode nine, viewers will meet Luka and Jonas. The former is a new student at school who Alaric will ask Jeremy and Bonnie to show around. Look for him to ask Bonnie about her ancestors and then privately tell Jeremy that his friend is "cute."

Might Bonnie not be the only witch in Mystic Falls?

Later in the installment, Joanes will befriend Alaric over their shared love of history, only to reprimand his son for telling Bonnie too much.

Where is this storyline headed? We ask those who have read the books to not spoil anything for viewers - and for everyone to visit our Vampire Diaries forum now to discuss!
