Despite her sometimes malicious behaviour toward others, she can make them feel very special, and is known by her close friends to have a sweet and caring side. The daughter Alison's parents knew, though fiercely independent and recklessly obstinate when challenged, was never the girl hated and feared by many. She never had a close relationship with her brother, Jason DiLaurentis. Although Alison seemed to have the perfect life, she was being harassed by a mysterious text-messenger named "A", shortly before her death.

Alison and Aria discovered Aria's father's affair with a college student, Meredith Sorenson, and found him kissing Meredith in his car. Ever since, Alison used the affair to keep Aria in line, knowing Aria was asked to keep it a secret. Her constant teasing about the indiscretion led Aria to resent Alison. Shortly after Ali's disappearance, Aria moved to Iceland for a year, and came back, sans pink highlights, becoming more mature. She meets her future English teacher Ezra Fitz in a bar, hooking up with him, leading to an on-again off-again relationship throughout the series due to A's threats. Due to the loose connection she and Ali shared, she is not a frequent target of A, but is still forced to deal with the misfortunes A brings upon her.

Her parents are very demanding, while her aggravating sister, Melissa, is constantly outshining her and winning their parents' scarce approval. With her fiercely competitive nature, Spencer doesn't demand anything less than perfection. Despite being very sure of herself, Spencer does begin to show a bit of strain when she and her friends start receiving strange texts from the mysterious "A." She is very protective of her friends, and can come off as being bossy at times, but only because she wants to protect them. After losing her boyfriend Toby to the A-Team, Spencer suffered from a mental and emotional breakdown and was admitted to Radley Sanitarium after being found lost in the woods with no ID. To avoid any more suffering and pain, Spencer soon agreed to become a member of the A Team, but it was only to find out information about Red Coat and to see Toby. As of “A DAngerous GAme," Spencer has been kicked out of the A-Team, as she was a double agent.
