The following article contains spoilers for Pretty Little Liars: Original Sin. The original ABC drama Pretty Little Liars featured approximately 15 characters who donned the black hoodie during their repeated battles against the Rosewood Liars. In the first ever episode, we were introduced to the infamous and dedicated tormented "A" after Alisons funeral. In Pretty Little Liars, "A" is often revealed to be another young town resident wronged by Alison or the other Liars in the past.
Pretty Little Liars: Original Sin goes far beyond the original's depiction of the hooded mastermind who stole from the theaters and who was appreciative of it. In Chapter One: Spirit Week, Imogens mother is discovered dead in a tub of her own blood, a gory sight we would have never seen in the original. A familiar letter is written on the tiles of the tub, revealing why the new Liars mothers are so different from the previous.
Original Sin, the first Pretty Little Liars spin-off to premiere on HBO, introduces fans to a new group of Liars: Imogen Adams (Bailee Madison), Faran Bryant (Zaria), Minnie Mouse Hondrida (Malia Pyles), and Noa Olivar (Maia Reficco). Both stories take inspiration from popular horror films, such as Chapter Seven: Carnival of Souls.
The most common question viewers might ask while watching Pretty Little Liars is "why don't they just go to the police?" Due to a fear that their own dirty secrets will be revealed, the Rosewood Liars are unable to divulge their secrets to the cops due to a fear that their own untrustworthy foes will be exposed. Eventually, "A" has the Liars so enthused, they break the rules.
The Liars continue to follow Millwoods' rules until his grand plan comes to an end. Like the Boogeyman, he isn't afraid to run after his victims.
Noa is chased around by "A" when she refuses to report her own mother to the authorities for stealing drugs. In Chapter Seven: Carnival of Souls, "A" does the same to Mouse. One of the scariest scenes is one that draws on horror classics like Carrie and I Know What You Did Last Summer.
In Chapter Five: The Night He Came Home, we see "A" looking through a trunk of old belongings in Imogen's basement. It appears that the photo is of Angela as a baby with an older brother or cousin. Also in the trunk is an ace of clubs, displaying two black As at either end.
The Millwood Liars will release the last three episodes of Season 1 this Friday, featuring both Imogen and Tabitha, who were abused by their mothers to death.
