With just one more episode to go before Charles' identity is revealed, the pieces are finally falling into place in ABC Family's teenage drama "Pretty Little Liars."

Tuesday's episode saw Charles stepping up his game when he hijacked Aria's exhibition. He replaced all her nominated photographs with that of the Liars asleep on the surgical tables in the dollhouse, and these photographs had the desired effect.

The Liars are still suffering from Post Traumatic Stress Disorder, and Charles hit their weak spot by reminding them of their time locked up in his dollhouse.

"FrAmed" also revealed some players on the A Team, with Red Coat making her return and spying on Aria and her family. Although Red Coat's identity was not revealed in the episode, speculations are rife that Melissa could be the one who has been torturing her sister Spencer, and her friends all this while.

Another person who has been acting shady is Aria's photography partner Clark, who was seen going into an old manufacturing company shortly after Rhys was seen going into the building.

Rhys is the new A suspect, thanks to his shady behaviour and his similarity to Jason DiLaurentis.

Meanwhile, the upcoming episode entitled "Last Dance" will see the girls' mothers throwing them a prom when the girls gets banned from attending Rosewood High School's graduation dance due to "security" reasons.

"At first reluctant, the PLLs agree and try to make the best out of a bad situation. But one to never miss a formal, Charles has other plans in store to make this a night they will never forget," the official synopsis of the episode reads.

Veronica, Pam, Ashley and Ella also use the prom night to reconnect with their daughters and find out everything that has happened to their daughters, the synopsis notes.

"Pretty Little Liars" airs Tuesdays on ABC Family.
