Mona Vanderwaal may be dead, but that doesn’t mean she can’t haunt the Liars in the PLL Christmas episode “How the ‘A’ Stole Christmas” 5x13.  Janel Parrish will be returning to play Mona as the Ghost of Christmas Past, Present and Future, complete with a creepy and cool Halloween-style costume.

Janel told zap2it that Mona will leave the Liars a clue in the Christmas episode.  Mona left the clue to help the Liars figure out what happened.

There will also be Mona flashbacks in the Christmas episode.  Janel posted this photo of a Hanna and Mona flashback to look forward to.

Janel has said that Mona’s death is going to affect Hanna the most.  “Hanna’s definitely devastated by her death”.

Wonder if the Liars will be able to figure out what Mona’s clue means?
