The Liars are totally back in Rosewood, and back on the police's prime suspect list in the second half of "Pretty Little Liars" season 6.

During the midseason premiere, something unexpected happened when Charlotte/Cece Drake/A (Vanessa Ray) was pushed to her death from the bell tower. This prompted the Rosewood PD to look for the culprit responsible for killing Ali's (Sasha Pieterse) sister.

The unexpected event tied the Liars to their hometown once again despite their new lives away from Rosewood. But can they prove that none of them has something to do with Charlotte's death?

In the previous episode, even her friends think that Aria (Lucy Hale) and Ezra (Ian Harding) did something suspicious during the time of Charlotte's death. Can they prove their innocence or did they really kill Charlotte to make her pay for tormenting them in the past?

But in the upcoming episode titled "The Gloves Are On," Hanna (Ashley Benson) will do everything to get herself and her friends off the hook with the help of Lucas (Brendan Robinson). Will this clear Emily (Shay Mitchell) and Spencer's (Troian Bellisario) names too?

The official synopsis for the upcoming episode states:

"Aria, Emily, Hanna and Spencer find themselves back in familiar territory with the Rosewood P.D. knocking at their doors looking for answers and their actions now affecting the loved ones around them. With her mother's job on the line, Hanna tries to come up with an alibi that could save all four of them with the help of her old high school friend, Lucas. Meanwhile, Emily comes clean about the last five years, and Aria goes the extra mile to keep Ezra's second book in play with her boss."

The synopsis mentions something about Emily opening up about her life during the past five years that she was away from her friends. Will the viewers finally find out why she has all those medicines that spilled from her bag during the midseason premiere and explain the blood extraction in the previous episode?

"Pretty Little Liars" season 6 episode 13 airs Tuesday, Jan. 26, on Freeform.
