Us Weekly and Pretty Little Liars have partnered up again to bring you a sneak peek at each week’s new episode with behind-the-scenes photos. Scroll down for more on this week’s pics, and check back every Tuesday morning to see new ones!

Here we go, #FAcetoFAce!

Pretty Little Liars‘ Season 6A finale, “Game Over, Charles,” airs tonight, Tuesday, Aug. 11. And in addition to finally finding out who, in Hanna’s words, that “bitch” Charles really is, we might be about to discover something else—what really happened to Ali the night she disappeared.

Feast your eyes on Miss DiLaurentis (Sasha Pieterse), all bloodied up and in the yellow tank top that’s lived a thousand lives. Her face? Pretty as a porcelain doll’s. Her curls, despite suffering the trauma of a rock to the head? Flawless. And her assailant? A mystery, but one that should be a little less enigmatic after tonight!

In the other three exclusive photos just for Us Weekly readers, the Liars and Mona (Janel Parrish) stand around a techy table that looks straight out of the Pentagon. You can see the series’ executive producer, I. Marlene King, guiding the actresses through their final scenes—before the first half of the season ends and the five-year time jump begins.

Plus, the pics give you one more good look at each of the lady’s prom clothing and beauty, including Ashley Benson‘s epic braided updo, which is even more complex than it looks. “Since Ashley has a bob, my challenge was to make a beautiful hairdo that still had a great design to it despite its length,” celeb hairstylist Kim Ferry told Us. “So I custom-built a small hairpiece to frame her head made out of human hair with small clips attached.”

Adding even more princess appeal, Ferry found small flowers at Michaels Arts & Crafts, which she glued to blonde bobby pins and worked into the design, always making sure to have extras on her “just in case.” After all, the ladies are meeting Charles tonight…

Tune into PLL’s Season 6A finale on ABC Family, Tuesday at 8 p.m. ET.
