There was so much game changing stuff going down in the last ten minutes of the Pretty Little Liars summer finale, that it’s left us neglecting some of the subtler developments namely, Hanna’s (Ashley Benson) sneaky confiscation of a certain item from the “A” lair. What did she take? Why is it important? And was she trying to hide it from the other Liars? We speculate below!

What was it?

Refresher! The Liars found what looks like “A's" lair in Ravenswood during the summer finale. Nestled amongst the creepy bulletin board timelines of their lives and photographic wall murals of Ali’s face, Hanna was drawn to a silver, padlocked diary (honestly, it looked a little bit like a 12-year-old girl’s). Hanna immediately nabbed it and stuffed it into her bag. The diary wasn’t mentioned again in the episode, as the Liars were busy following the trail of their apparently-alive BFF.

Why is it important?

We can’t help but think this diary spells bad news for Ezra. It’s probably littered with Aria love poetry that Ezra doesn’t want his ex-beau to see. Oh yeah, and they might discover he’s “A.” Also, PLL showrunner Marlene King mentioned that the diary “becomes a great vehicle for the girls to find out more answers about Uber ‘A’ and Alison.” Did the diary actually belong to her? Will it reveal how Alison and Ezra possibly knew one another? In the same answer, Marlene mentioned Ezra flashbacks. Will we get some scenes with these two seemingly unrelated characters together. hopefully with the Super Secret Silver Diary in tow?

Was Hanna hiding it?

From Marlene’s comments, it seems like dissecting the diary will be a group project, but we couldn’t help but notice Hanna seemed super shifty when stashing it in her bag. Was the shiftiness due to being in “A”’s lair (because, understandable), or was she trying to keep the diary a secret from her friends? Perhaps she’s seen Ezra with it before and doesn’t want to hurt Aria before she knows more? More likely, she has seen Ali with it before. Could this be another diary that Ali was keeping, even more juicy than the one Mona keeps on her iPad?

What secrets do you think the diary holds? Is is Ezra’s or Alison’s? And was Hanna trying to keep it a secret from the rest of the Liars? Sound off in the comments below!
