Time For Pi equals 3
The Brew’s logo is of three crows. Originally, there were three crows. Spencer, Bethany and Twincer - or should I say, Tripencerany (sorry!)
In this, I will use Twincer until we know her name.
In 7x19, someone receives a note with the words “TIME FOR PIE. BE THERE.” with two crows at the top - The Two Crows.
Pie has been mentioned a lot during the show but the one that sticks out to me, is the episode “Gamma Zeta Die”. The “Die” replacing “Pi” in the Greek Alphabet. In this episode, Spencer is searching for the person Ali has been speaking to at Cicero College, Mrs Grunwald.
Later, Spencer and Toby head to Ravenswood to search for Grunwald, where there were crows circling above them and one smashes into the windshield and dies.
One of the 3 crows, Bethany died. Leaving only Two Crows left. Spencer and Twincer.
No one knew that Mary was expecting triplets. Spencer was born first and was handed over to Veronica when she was “less than 5 minutes old.” A few minutes later, another baby was born… And then another. Veronica had already left with Spencer, so Twincer and Bethany were put into the system and were fostered together.
In the last episode, we saw “Spencer” visit Toby. I got strong twin vibes from the way she was acting. When they got it on, he stroked her bullet wound scar BUT it wasn’t Spencer’s bullet wound. It was Twincer’s stab wound, inflicted on her by her sister, Bethany.
There are more triplet clues but I can only remember these off the top of my head - 3 skeletons in Wren’s apartment. 3 skeletons in the dollhouse.
Wren and Twincer either met in the foster system, were adopted together or he is Charles.
I also think Grunwald has more to do with the story. She was in Radley because of her power of sensing things and she has a strong link to Charles.
