When Klaus and Elijah receive a cryptic invitation to dinner from their mother Esther, who continues to inhabit the body of Harvest girl Cassie (recurring guest star NATALIE DREYFUSS), they find themselves preparing for the worst. With the help of a new witch named Lenore (recurring guest star SONJA SOHN – The Wire, Body of Proof), Klaus, Elijah and Hayley attempt to stay one step ahead of Esther, but things quickly take an unexpected turn. While Elijah finds himself reluctantly teaming up with Gia (recurring guest star NISHI MUNSHI – Pretty Little Liars), a newly turned vampire, Hayley is faced with an enticing proposition about her new status as a hybrid after a startling encounter with Esther. Finally, Esther reveals a shocking secret about Klaus’ childhood and unveils her ultimate plan for her children. Recurring guest star ALICE EVANS (The Vampire Diaries) guest stars in flashbacks to the Mikaelsons’ childhood.
