The Liars have discovered a cabin that is not the cabin. The princess is in another castle. Well done, ladies.
TO THE LIGHTHOUSE
Is his real name, which is why it doesn't matter that everybody knows where and with whom Emily was meant to be vacationing. Anyway, eventually Emily just sort of runs out of the room under no pretext at all, like it's edited to seem that he hears the Liars coming and is distracted, when in fact what distracts him is the script so that Emily can mosey on out of there... and all the way up the 400 steps of the lighthouse, a structure known for having no exits and going straight up and illuminating you constantly so that anybody chasing you through the forest will know exactly where you are.
Did I say that was the stupidest thing, before? Hmm. So what happens, anyway, is that she finally gets a signal at the top of the tower -- ah, got it, sorry -- and he comes running up after her, they tussle with the knife, Emily stabs him through the gut, he falls down bleeding out and dying, Caleb comes running up with his gun, which he places gently within Lyndon's reach so he can give Emily a comforting hug and then his dumb ass gets shot through the abdomen. And I hate to say he was asking for it, because I do love my Caleb, but Jesus F. Christ with these people.
LATER, BUT ALSO EARLIER
Hanna screams Caleb's name about a thousand times, filling in the blanks now that we know, and the poignant "was he your friend" thing comes back around full force. Was Nate St. Germaine Emily's friend? Definitely. Was Lyndon James? Well, how about Mona?
How about Alison?
But when Emily shouts, "Just let me talk to my friend!" You know who she's talking about. And so does Paige. So when Emily goes running into Hanna's arms, she and Spencer spare a look every bit as painful, and as beautiful, as the time they sent the whole school running. It was about how much they loved Emily. A whole fight, a whole war -- not unlike the one Alison started with her, really -- about who loved Emily more, who was allowed to love her more.
