Viewers will see Alison (Sasha Pieterse) attempting to look for more information regarding her deranged brother Charles in the upcoming episode of ABC's teen drama/mystery/thriller series "Pretty Little Liars."

In "FrAmed," the International Business Times reports that Alison will dig deep in her memories and the family's photo albums to find out more about her brother. She will have a hard time, however, in connecting the demented image he is now projecting to the cute blonde boy he was years ago.

Meanwhile, there will be a definite scramble for safety among the Liars after their latest run-in with Charles. The girls are definitely worried about what "A" will do to them, as it is obvious he is out for blood when Jason's (Drew Van Acker) attempt to meet him went awfully wrong.

Amid the looming chaos, however, they will still have time to agonize about personal matters. According to Wetpaint, Aria (Lucy Hale) will be distressed to find out that her big moment of seeing her art work displayed in a gallery is in peril after her mother Ella (Holly Marie Combs) refuses to let her go outside the house. Hanna (Ashley Benson), on the other hand, will still be unsure whether to accept the scholarship money she believes came from Charles, even if it means not going to her dream school. 

To top it all off, it seems like the Liars will not be allowed to attend the prom for security reasons. Rosewood High will decide that having them among the other students is inviting disaster. What if Charles goes to the prom and seeks them out?

Last week's episode ended with a chilling note. Alison and Jason returned home to find a home video playing in the attic. In the footage, they saw their younger selves playing with a second cousin named Freddy. Apparently, the little boy was Charles, as he could also be seen later in the footage asking Mrs. DiLaurentis (Anne Marie DeLuise) when he had to go back somewhere. With the video was a note, which read, "I wAnted to trust you."

"Pretty Little Liars" airs Tuesday at 8 p.m. on ABC Family.
