If you thought Spencer (Troian Bellisario) would share Toby's (Keegan Allen) secret with the other Liars ASAP, you thought wrong, as we can see in this sneak peek of Pretty Little Liars Season 3, Episode 17: “Out of the Frying Pan, Into the Inferno” (January 29).

As Aria (Lucy Hale) laments her inability to tell Ezra (Ian Harding) about his son, and Hanna (Ashley Benson) wonders why Caleb (Tyler Blackburn) is acting weird, Spence tries to appear happy, but we can tell she's on the verge of tears. She should probably tell her friends the truth, but we can understand why that's hard for her.

Check it out below.
