Charles DiLaurentis

Charles DiLaurentis is the older brother of Alison DiLaurentis and older half-brother of Jason DiLaurentis. As a child, Charles was admitted to Radley Sanitarium, due to what Kenneth DiLaurentis, his father, described as behavioral episodes. Charles was confirmed to be the Big A who stole the game from Mona. Although Charles was assumed alive, it was revealed in "Don't Look Now" that he had supposedly killed himself at the age of 16 through pill overdose. However, with the medication he was taking he couldn't donate his organs. In the following episode, "No Stone Unturned" it was revealed by Mona (through Lesli) that he escaped "that night"  with Bethany Young, meaning that he was alive after he turned 16. So now Charles would be 25 years old.

Biography
Charles was fifteen months older than Jason. As a child, he worried his parents, Kenneth and Jessica, as he suffered from many behavioral episodes and these may or may not have been violent and/or psychopathic. Charles was admitted to Radley when Alison was eleven months old. He tried to drown Ali, by placing her in a bathtub full of scalding hot water. Kenneth discovered Charles attempting to drown her, and decided it was time for Charles to be admitted to a mental institution.

As a child, Jason was convinced he had an imaginary friend named "Charlie". When Jason asked his father where Charlie was, his father told him Charlie had to "go away for a while". It was later revealed that "Charlie" was actually Charles, and was a real person. Jason resents his father for lying to him about Charlie's existence.
