“Pretty Little Liars” is a popular TV series that aired from 2010 to 2017. The show revolved around the story of four high school friends, Aria, Hanna, Spencer, and Emily, who were reunited after the mysterious disappearance of their friend Alison DiLaurentis. The girls soon began to receive threatening messages from an anonymous source known as “A,” who seemed to know everything about their secrets and their past.
One of the major plot points in the show was the question of who hit Alison with a rock, which ultimately led to her disappearance. The mystery surrounding Alison’s attacker was a key driving force of the show’s plot and remained a central mystery for several seasons.
In season four of the show, it was revealed that Alison’s attacker was none other than her own sister, Charlotte DiLaurentis, who had been previously known as Charles DiLaurentis. Charlotte had been born a boy and was the older brother of Alison. However, due to her father’s disapproval of her gender identity, Charlotte had been sent away to a mental institution, where she underwent several traumatic experiences. It was there that she developed a deep hatred for Alison, whom she believed had abandoned her.
Charlotte had been seeking revenge on Alison for years and finally got her chance when the two had an argument in the backyard of the DiLaurentis house. During the argument, Charlotte hit Alison with a rock, which ultimately led to her disappearance. Charlotte then assumed the identity of “A” and began to torment Alison’s friends in an attempt to keep them from discovering the truth.
The reveal that Charlotte was Alison’s attacker was a major twist in the show’s plot and led to a significant shift in the dynamic of the show. The revelation also led to the introduction of several new characters, including Charlotte’s mother, Mary Drake, and her half-sister, Spencer’s twin, Alex Drake.
In conclusion, the answer to the question of who hit Alison with a rock is Charlotte DiLaurentis. The mystery surrounding Alison’s attacker was a key plot point in the show “Pretty Little Liars” and was finally revealed in season four. The revelation led to a significant shift in the show’s dynamic and the introduction of several new characters.
