Synopsis
Three months have passed, and Mona’s friends and family are still mourning their loss and more adamant than ever that Alison had something to do with Mona’s death. Ready to put “A’s” game to an end and get justice for Mona, the Liars ramp up their search for evidence that could prove Alison killed Mona. But with Alison claiming her innocence and having a seemingly airtight alibi, the Liars may have to resort to more shady tactics to put Ali away.

Meanwhile, Emily and Paige reach a crossroad in their relationship, and Aria starts to worry about her future.

Title and Background

 * The title may be a reference to "In a Glass Darkly," a collection of five short stories by Sheridan Le Fanu. The collection's title is a deliberate misquotation of 1 Corinthians 13:12. The last of the five stories is "Carmilla," a tale about a female vampire that served as inspiration for Bram Stoker's Dracula.
 * The title may also refer to the bible verse 1st Corinthians Chapter 13. "For now we see through a glass darkly but then face to face" As though when someone was naive or didnt know something, they were blinded to the truth.
 * The title may also be reference to the Ingmar Bergman chamber film "Through a Glass Darkly" (1961). The events of the film are set on an island and take place within a 24-hour period. There are only four characters in the film, which may be a point of similarity with the four main characters in the show.
