The ABC family drama has revealed A's birth name, but the quest to unmask the Liars' tormentor is still on. While we now know none of the core four bare the killer's mantel, it remains to be seen if one of the teens is in league with the notorious villain.

Lucy Hale (Aria) is currently unable to comment on a possible A affiliation - viewers will just have to wait and see - but the actress did recently reveal one major teaser for the summer season.

"I can't talk about the storyline, but it's sort of a big reveal dealing with an A storyline," Hale told 17. "It's actually a joke with the fans and Aria, because Aria's usually not involved in the forefront with A - she's sort of just missing in action. But Aria finally gets to do something courageous, which was really fun. We were up all night shooting it, but it's a pretty big reveal - it's one of those bombshells."
