You know something big is going down on Pretty Little Liars  when the genius behind the entire show needs some time to comprehend it all.

Read spoilers at your own risk! For more on Wetpaint Entertainment's philosophy on spoilers, click here.

The PLL showrunner took to Twitter yesterday to express her thoughts on the end of Season 3. “Believe it or not, I'm starting to wrap my brain around the season 3B finale,” Marlene King wrote.

What could be so big that Mar needs some time just to start to wrap her head around it?! Could there be another epic betrayal?

All we know about the finale is that it will turn Spencer’s (Troian Bellisario) world upside down. Could that be what Marlene is talking about? What would hurt Spencer more than Toby’s (Keegan Allen) reveal?

If another member of the “A” team is revealed, who are you top suspects? And if not, what do you think will happen?

Are we talking about yet another death in Rosewood? Or is it something we haven’t seen yet. Perhaps the arrival of Alison’s (Sasha Pieterse) possible, maybe, potential twin?

What would blow your mind the most? The sheer anticipation is overwhelming. Needless to say, we are shaking in our rain boots.

Don’t miss the next new episode of PLL, the Halloween special, on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
