Pretty Little Liars Season 3, Episode 16: "Misery Loves Company" included a moment so shocking that even the cast and crew were blown away when they watched the final version unfold on Tuesday night.
We're talking, of course, about Spencer (Troian Bellisario) learning the truth about Toby (Keegan Allen). Fortunately, some of the cast watched the show together at showrunner Marlene King's house, and they recorded their reaction for posterity.
Check it out below! We especially like Shay Mitchell's (Emily) scream.
Catch the next episode of Pretty Little Liars on Tuesday, January 29, 2013 at 8 p.m. ET/PT on ABC Family.
