Alison (Sasha Pieterse) gave us quite the stealthy surprise when she was seen writing in her journal during Pretty Little Liars Halloween episode –– and apparently there’s more to this burn book than meets the eye!

PLL’s show runner, Marlene King, took it to Twitter and served up a big plate of diary-related spoilers:

“Halloween spoiler. When Jason [Drew Van Acker] walks into Ali's bedroom she is writing in her journal,” tweeted Marlene. “It's relevant.”

We would give up our entire collection of Aria-inspired feather hair clips for a glimpse at this book of secrets, but the real question is: Where is Ali’s journal now? Does “A” have it in his/her lair, or will the little liars get their freshly manicured hands on it first?

One thing’s for sure: If Alison knows who “A” is, you can bet her journal does too.
