Mona is Remembered in Tonight's 'Pretty Little Liars' Winter Premiere

Toby (Keegan Allen) comforts Spencer (Troian Bellisario) in this still from tonight’s winter premiere of Pretty Little Liars.

In “Through a Glass, Darkly,” three months have passed, and Mona’s (Janel Parrish) friends and family are still mourning their loss and are more adamant than ever that Alison (Sasha Pieterse) had something to do with Mona’s death.

Ready to put “A’s” game to an end and get justice for Mona, the PLLs ramp up their search for evidence that could prove Alison killed Mona.

But with Alison claiming her innocence and having a seemingly airtight alibi, the Liars may have to resort to more shady tactics to put Ali away.

Meanwhile, Emily (Shay Mitchell) and Paige (Lindsey Shaw) reach a crossroad in their relationship, and Aria (Lucy Hale) starts to worry about her future.

Pretty Little Liars returns TONIGHT, January 6 @ 8PM on ABC Family.
