It's been two weeks since "Pretty Little Liars" opened up Pandora's Box and revealed Cece as A, and Marlene King is pinpointing the first fan to guess the reveal correctly.

On Saturday, King posted to Instagram the first "Pretty Little Liars" fan she saw who had the right theory regarding Cece, and gave a hearty congratulations.

"This is the first person I saw on social, months ago, who realized CeCe/Charlotte was A and also got the story almost completely correct," wrote King. "He was so accurate I never commented on his posts. Congrats! You nailed it! Please be nice to him!"

Known as Ceceice in the "Pretty Little Liars" reddit community, fellow fans posted similar niceties online as well.

But not all mysteries are solved yet on the series. There is still the issue of the new "big bad" slated to disrupt the Liars' lives five years after Season 6A finale, and we still are waiting to find out who killed Mrs. DiLaurentis.

But one particular Liar still remains shrouded in intrigue and mystery, despite not being A.

"Cece seemed to have a really weird obsession with Aria this season," wrote reddit user Katcloud. "Even with that tennis ball doll and the doll in the junk yard with two heads. I wonder if that was relevant at all, like why would she hate her more?"

A still popular theory is that there remains a twin on the show that has yet to be revealed, and it is one of the major reasons an older Bethany Young's face has not yet been revealed.

"It's been heavily hinted that there is a twin and it's been suggested that Aria is perhaps more connected to the storyline than we think," wrote reddit user HandsomeLittleLiars.

"I think that Bethany is Aria's twin, and that the Montgomerys adopted her. It was Aria that made the connection between adoption and lying about age, so I think that it's possible she is the one who was adopted. I think that Eddie Lamb genuinely thought he recognized her, but the 'she' he recognized was Bethany's face if you get me?"
