It was revealed that Spencer’s mother, Mary Drake, gave birth to twin girls. While Spencer found a loving home in Rosewood, Alex was sold to a wealthy British couple, who later left her at an orphanage.

While Mary Drake had hoped Alex would have the perfect Cinderella story, she ended up learning about Spencer’s existence, and made it her mission to get revenge.

The Liars knew of A.D.’s existence, but could never have guessed that it was Spencer’s long-lost
twin the whole time!

“Pretty Little Liars” ended with the gang discovering Alex’s real identity, and locking her up for good … or so they thought.

In the last moments of the show, Mona turned the tables on A, and had Mary and Alex Drake
locked up in what seemed to be another dollhouse.

Luckily, Spencer, Aria, Hannah, Emily and Alison finally had a happier ending and are free from A after seven long seasons!
