HELLO! If you're reading this, you've definitely watched the Pretty Little Liars finale, RIGHT?! Because this post is full of spoilers. YOU HAVE BEEN WARNED.
First of all, in the Season 7 poster, Spencer is framed differently to the rest of the girls.
This is the twitter bio for Troian Bellisario, the actress who plays Spencer. But only sometimes.
Remember that letter from Mary Drake that Spencer got from the board game?
A scene from the first episode of Season 7 showed Hanna being held captive in a barn by A.D.. While there, "Spencer" appeared to Hanna "in a dream" to help her escape.
And Mary Drake dropped this whopper in the same episode, when talking to Hanna.
We found out early this season that Mary Drake had a baby who was put up for adoption.
Then of course, there was the shady airport scene which set alarm bells ringing straight away.
Another twin scene was the one in 7x18 when Spencer met up with Toby in his cabin, where they had sex.
Also, the actor who plays Toby tweeted this ~seemingly innocent~ commentary on the episode.
Spencer was always wearing a watch, while her twin was not.
In the airport scene and the Toby sex scene, "Spencer" is bare-wristed. In every other scene in these episodes, she's wearing her signature black watch.
We should have known! I.Marlene gave us this clue about watches on Twitter.
The actor who plays Caleb gave us a giant fucking hint.
Having Aria and Mona FaceTime fake versions of themselves foreshadowed a fake Spencer.
Remember back when Spencer was in Radley, and she had this vision of a mini version of her?
This is a bit of a stretch, but hey. This shot from Charlotte's dollhouse shows her ideal childhood.
Also, in the dollhouse, the girls came face to face with A (aka Charlotte). Spencer's reflection lined up perfectly with the mask.
Veronica dropped this line, way back in Season 4 when Spencer was dealing with a pill addiction.
Sure, she's clearly not ACTUALLY referring to Alex. But the hint is there.
