Pretty Little Liars showrunner Marlene King sure does know how to tease fans on Twitter. She's constantly answering questions with just enough info to make us even more anxious to watch new episodes of the show.

Recently, she went as far as tweeting what seems to be a cryptic little passage from the Season 3 premiere.

Yesterday, Marlene, tweeted, "EXT. COURTYARD - HIGH SCHOOL - DAY 'Do we think it's a coincidence that he turned Boo Radley after 'that night?''"

Not only is Marlene currently working on the Season 3 premiere script, but she has previously said, "Title of premiere episode - It happened 'that night,''" so we're pretty sure this is from that episode.

So, what does it mean? For those who need to brush up on their American Lit knowledge, Boo Radley is the reticent, misunderstood loner at the heart of To Kill a Mockingbird, so we assume this sentence is in reference to a character becoming evasive and seemingly creepy.

Once upon a time Toby (Keegan Allen) fit the Boo Radley type perfectly — remember when the Liars all thought he was dangerous? — so it's possible they're talking about the way he used to act after Alison's (Sasha Pieterse) disappearance. 

Of course, Jason (Drew Van Acker) could arguably also fit the bill with his loner tendencies after his sister disappeared, and it's also possible they're talking about something else entirely. Maybe a different character gets reclusive after something that happens at the end of Season 2...

Be sure to tune in for the next episode of Pretty Little Liars on Monday, March 12 at 8 p.m. ET/PT on ABC Family.
