Pretty Little Liars returned with its winter premiere “Who’s in the Box?” with relationship drama for all of the girls. Beware of spoilers!

The episode begins with Hanna (Ashley Benson), Emily (Shay Mitchell), Aria (Lucy Hayes), and Spencer (Troian Bellisario) trying to figure out where Ali (Sasha Pieterse) was for all of these years. Spencer wants to find out who Ali was running from while the other girls speculate that Ali could be A. The Pretty Little Liars try to figure out who Ali was so afraid of. Looks like this will be the mystery of the season.

Hanna has some issues pronouncing gazebo and wants the girls to find out who really is in Ali’s coffin. Spencer gives her props for coming up with an actual theory and looks like we have a mystery!

Emily questions Mrs. DiLaurentis (Andrea Parker) about Jason (Drew Van Acker) who wants his private time while she changes Ali’s old sheets. Ashley (Laura Leighton) is having trouble finding a job after the criminal charges.

Toby (Keegan Allen) and Spencer reunite while Paige (Lindsey Shaw) and Emily experiences a rough patch. Mona (Janel Parrish) tries to win Hanna over but Hanna has trust issues. Ezra (Ian Harding) talks to Aria, while creepy music plays, and Hanna shows the others her research about missing girls.

The girls get dared by A via an educational video to find Ali. It seems to be a clue as the writing was on a blackboard, perhaps pointing to Ezra.

Ezra apologizes to Aria while trying to get a second chance with her. What do you think, Ezria fans?

Spencer asks her dad (Nolan North) about Jason but gets stonewalled. Toby continues to press about his mom’s supposed suicide and finds witnesses to show that his mother was murdered. Hanna is convinced that the PLL’s have a responsibility to find Ali while Caleb (Tyler Blackburn) surprises her.

Emily and Hanna meet with two girls whose friend went missing the same time as Ali. Hanna thinks the girl could be buried in Ali’s grave. Mona hits on Ezra and lets him know that she’s onto him. Spencer and Toby pressure the owner of Radley to let them investigate Toby’s mother’s death.

Ashley is going to work with Mrs. DiLaurentis in her real estate office as Ali suggested it to Mrs. DiLaurentis in a dream. Spooky.

Caleb breaks the news to Hanna that he has to go back to Ravenswood while Toby celebrates clearing his mother’s memory with Spencer. Spencer’s dad congratulates them and encourages them to think bigger and try to shut Radley down.

Aria calls Ezra and the two journey to his friend’s cabin in the woods. They talk about the demise of their relationship as they confide that they have struggled with the ending of it. Ezra proposes the cabin as their secret hideaway and Aria agrees with a kiss.

After a private meeting with one of the girls who lost her friend, Emily confides in Paige about her relationship with Ali. Emily confesses that Ali broke her heart and she does not believe that Ali ever loved anyone.

Hanna and Caleb fight over him going back while Hanna thinks Miranda (Nicole Gale Anderson) is somehow involved. Ashley comforts Hanna as Caleb abruptly leaves, ending their relationship. Hanna follows him out and ends their relationship on a civil note. Back at the cabin, Ezra eyes a trap door while Aria stares out the window.

The episode ends with the girls still unable to find who is in Ali’s grave. Hanna shows the girls Ali’s diary that she found in Ravenswood. Sh hid it from the girls because of what it said about them all.

A entered Ezra’s friend’s cabin only to pull open the trap door. Who or what do you think is inside?
