The Christmas episode special of 'Pretty Little Liars' season 5 will be intriguing, as the mysterious 'A' is expected to walk around, just a few feet away from the lead characters during the Christmas Ice Ball.

In a photo released from the upcoming episode Aria, Hannah, Spencer and Emily can be seen looking startled in their ice ball dresses, and it could be due to 'A's presence.

Actress Janel Parrish spoke to TVLine about 'A's decision to torment the girls during the holiday season, and she just might be planning something that will ruin Christmas this year.

"She's going to be the Ghost of Christmas Past, Present and Future," Parrish revealed. "She gets to mess with Alison — and in a fabulous costume, I might add," Parrish said to TVLine.

A video for the new episode shows Alison entering the party with her new female friends, while her old pals have a confused and stunned expression at the presence of the former queen of the squad.

The video also shows a woman wearing a white, oversized coat, emitting a vibe that she could be the infamous 'A.'

Show creator, Marlene King, wrote in her Twitter account that she will direct the upcoming Christmas episode.

"I am extremely excited to write the PLL Christmas episode. And I'm directing that one too! @PLLlittletheory," King wrote in her Twitter account.
