The Tribune

Who's the person behind the mask this time? We'll theoretically find out tomorrow (though we supposed "Who's the Person in the Gas Mask?" could become the new "Who's the Queen of Hearts?"), but that still leaves us some time to speculate.

So, here are our best guesses about who might be stalking the Liars through Ravenswood wearing one very disturbing costume.

Ezra. This is the obvious answer. We saw the gas mask in "A"'s lair, we saw Ezra in "A"'s lair...put two and two together, and you've got creepy EzrA stalking the Liars in the world's most frightening costume. That said, based on the promo we know that a non-masked Ezra appears in the episode at some point. Obviously that doesn't exclude him from being the one behind the mask (and he is in military gear at some point), but it does make us less confident that he's the one behind the mask.

Luke. Luke is a new character from Ravenswood, but that doesn't exclude him from appearing in the Halloween episode, and we know he is, like Ezra and the gas mask wearer, dressed in military gear. Plus, this script spoiler hints that the Liars will find themselves suspecting someone they've never met before of being "A". Maybe it's because they see Luke wearing the gas mask.
