Ready to spend a night at the opera with The Originals?

Following The Originals Season 1 Episode 14 - an incredible showcase for Claire Holt that revealed her character's darkest secret - this freshman drama will go back to 1919 again on Tuesday's "Le Grand Guignol."

We'll spend time in the old days with Klaus, who opens up to Cami about his family's betrayal, while also promising to make Marcel and Rebekah (who are on the run) "pay" for their transgression.

Elsewhere on The Originals Season 1 Episode 15, Elijah will form an unlikely alliance while Hayley will hold Sabine Celeste hostage in order to gain information about her clan.

Watch the official network teaser now and wonder what could possibly happen next:
