Yesterday, December 19, Pretty Little Liars showrunner Marlene King took to Twitter to chat about Alison DiLaurentis (Sasha Pieterse) with the writer of the Pretty Little Liars books, Sara Shepard. While the entire conversation is worth checking out, we want to highlight a few specific things Marlene said about Ali on the show.

Vulnerability: Marlene noted that "we haven't seen much vulnerability [from Ali] on the show yet ... But Season 3b sheds a little light on it." Will we finally get to see more of the cracks that must have existed in Ali's armor?

Ali and Byron: Marlene also said, "we hinted at Ali having a secret connection to Byron [Chad Lowe] in the last episode. There's more to come."

A creepy basement. When Sara said she can't wait to see where the Ali and Byron story goes, Marlene teased, "A creepy basement is involved."

And the most common question is... This isn't a spoiler, but we found it interesting that apparently the most common question Marlene gets about Ali is "does she have a twin on the show." Everyone wants to know!
