One question still left unanswered come the final shot of the Season 3 finale is the identity of the elusive Queen of Hearts, seen drugging and then locking Aria (Lucy Hale) into a box with dead Garrett in the Halloween train episode. Seems like a dangerous type to have out and about. Will her identity be revealed in Season 4? Pretty Little Liars writer Bryan Holdman says...

Yep! Bryan tweeted this teaser last night: “I don't wanna spoil the pie, but in S4 it's ‘Off with her head!’ Or off with the mask, at least...”

The first part is a reference to Alice in Wonderland, the literary tale from which the Queen of Hearts character hails, and Bryan assured fans that it shouldn’t be taken literally. There will be no beheadings. Probably. De-maskings, on the other hand...

We saw a glimpse of the Queen of Hearts in the Pretty Dirty Secrets webisodes. If it was the same person donning the costume on the train (and not trying to disguise herself further), she is small-framed and has brown-hair. Quite a few people match this description on the show. Could it be Jenna, who we now know is working and/or romantically involved with costume store employee and all-around troublemaker, Shana? Or perhaps it is Melissa, who never seems to be up to any good?

Who do you think the Queen of Hearts is? Are you excited for the reveal? Let us know in the comments below!
