We fans may be the ones who storm the interwebs with our enthusiastic reactions of the most recent episodes of Pretty Little Liars, but the PLL crew are the first to experience the best OMG moments from the show. Which upcoming Season 4 episode had the PLL crew audibly shocked?

It looks like the episode to look out for is Season 4, Episode 10: “The Mirror Has Three Faces.” PLL writer Maya Goldsmith described this moment during filming: “Just shot a scene for 410 where several crew members gasped. Love it when that happens!!”

Maya’s tweet piqued our interest more than any vague tease might have, but the tenth episode was already on our radar for a few reasons. For one, Ryan Guzman (Jake) will be losing his shirt and showing off his well-toned bod in this hour. Secondly, Haleb has a scene that is going to “melt our hearts.” Add a good old-fashioned gasp-inducing moment, and you’ve got yourself an episode!
