Spencer (Troian Bellisario) is the one who jumped at the opportunity to get Caleb's (Tyler Blackburn) help in exchange for lying to Hanna (Ashley Benson) on Pretty Little Liars Season 2, Episode 17: “The Blond Leading the Blind.”

However, based on this preview from Canadian channel Much Music, even her determination to get to the truth won't stop Spence from feeling majorly guilty about pulling the wool over one of her bestie's eyes on Season 2, Episode 18: “A Kiss Before Lying.”

Will Spence fess up? Watch the preview here:
