On Season 6 Episode 14 of “Pretty Little Liars,” the girls discovered that Charlotte’s (Vanessa Ray) demise was not their main problem. Someone is apparently planning to get them again and Byron Montgomery (Chad Lowe) is not the killer.

Although he collaborated with Ashley to delete the video, that would be his entire involvement. It seems that the storyline will follow the same approach when the girls had a lot of suspects until they narrow down the list of potential murderers to someone unexpected or whom they have known for a long time, writes TV Fanatic.

International Business Times notes that in Episode 15, titled “Do Not Disturb,” the Liars will be teaming up to acquire answers to their new tormentor. They initially suspected that Ezra (Ian Harding) was behind the deed. They will also be looking at Sara Harvey (Dre Davis). Sara will not be providing the girls with direct answers on how much she was involved with Charlotte. Spencer (Troian Bellisario) and Aria (Lucy Hale) will come up with a plan to break into Sara’s hotel room to get proper answers.

The new stalker previously forwarded the girls a photo of the murder weapon – a nine-iron club. They eventually realized that the photo was taken in the hotel, which may implicate Sara. The girls also assume that Aria’s father, Byron, may have a hand since he entered the hotel carrying a bag.

According to CarterMatt, Sara will be the main suspect in the episode due to her creepy behavior and secretive ways. However, she might also be too convenient and easy. “Pretty Little Liars” generally does not give out the suspect’s identity too soon.

Caleb (Tyler Blackburn) and Hanna (Ashley Benson) will also be working together and will use the security tape to try and identify the new villain. The story will also look closer into Aria’s (Lucy Hale) background. She will get some news from her family.

As the girls continue their investigation, Ali (Sasha Pieterse) will have a surprise visit from Sara. In the promo video for “Do Not Disturb,” Ali and Sara were shown meeting inside a classroom. Sara told Ali that they never really knew Charlotte. Sara said in another scene that when no one else was there for Charlotte, she was. The video also showed Emily being admitted to a medical facility, albeit restrained.

Compared to previous stalkers, however, the new one seems to be bolder and is not expected to stay hidden for long.

“Pretty Little Liars” Season 6 Episode 15 will air on Feb. 9, 2016 on ABC Family.
