Mary Drake paid a visit to the Hastings family almost as soon as she settled in Rosewood.
Later in the season, Dr. Cochran told Aria and Spencer that "...you always return to family in the end."
She seemed particularly interested in the photograph of Spencer and her sister Melissa.
She remarked that they looked "almost like twins."
Toby told Spencer that he'd always loved her "tenacity."
Such a perfect way to describe her!
Dr Cochran then described Mary's second child as being "underweight, but tenacious."
Spencer certainly seemed thoughtful when she was leafing through her family albums.
She was the cutest kid!
Peter and Veronica have had their fair share of secrets in the past...
Could this be one more?
Melissa Hastings has also been the ultimate secret keeper!
Has she known all along?
Remember when Spencer found out that Jason was her half-brother in season 2?
Maybe her ties with the DiLaurentis family are even closer than she ever imagined?!
Mary made the jaw-dropping revelation as she cradled a gravely injured Spencer in her arms in the epic summer finale!
Are you still in shock?
Our minds are blown!! So Veronica is not Spencer's birth mom, but is Peter Hastings still her dad?
Let us know your theories below.
