The spying begins again when "Pretty Little Liars" returns in 2016. In a sneak peek for the second half of the sixth season, Spencer is mocking Aria for owning a selfie stick, which the latter claims to come in handy when they're trying to find out what happens to a room next door. But Spencer takes the action to the next level, using her acrobatic skills to leap between balconies to get a better view.

In another scene, Aria is apparently among suspects of an unknown crime and someone is trying to hit one of the girls with a car. The new baddie also sets off an explosion, prompting Hanna to suspect that their new tormentor is not "A."

According to the official description, picking up five years after we last saw the Liars, the girls are not the same people they were when they left Rosewood. Having pursued their own paths and adjusting to a life without "A," how will they be able to cope when something happens in Rosewood that forces them to go back to where it all started? Torn between their old habits and their new lives, the Liars must stick around, and together, as relationships are once again put to the test and new secrets are revealed.

"PLL" returns January 12 at 8 P.M. ET on ABC Family which will change its name into Freeform beginning in 2016. The show recently cast David Coussins as Hanna's fiance named Jordan, and Kara Royster as Toby's mystery girl Yvonne Phillips.
