8 Theories About Spencer's 'Pretty Little Liars' Ending That Are Beyond Intriguing

I do not know how Pretty Little Liars will end. I don’t know who will survive, who will die, who will come forward as A.D., who will admit they’ve aligned with A.D., or what the Liars will do when this sinister game finally draws to a close. (Heck, I don’t even know if this sinister game will ever draw to a close. What if the finale offers up an “…And they all continued to battle A.D. happily ever after” epilogue? Wouldn't put it past PLL.) And I really do not know what the Pretty Little Liars finale will hold for Spencer Hastings.

For the last seven years, I. Marlene King’s mystery series has led viewers on a twisting, confounding, and occasionally straight up dark ride. And as this glorious ghost train of a program careens toward its final stop, the questions continue to pile up like used coffee filters in the Hastings house. One of the many festering mysteries: What will Spencer’s PLL ending look like? Because I'll be darned if the show hasn't hinted at a Spencer twist.

Though I can't say what the finale has in store for Alison DiLaurentis’ cousin, I will say that I can count on Reddit for theories that’ll keep my mind running a mile minute. If you prefer to watch PLL without predictions clouding your viewing experience, then maybe turn back now? No shame, no judgment. But if you’re down to clown, please stick around for a few noteworthy theories about our dear Spencer. (If you're not caught up, fair warning: spoilers ahead.)

Theory #1: Spencer Has A Twin


The Spencer Twin Theory is the Spencer theory (and has been for quite some time), but the theories about The Spencer Twin Theory are where stuff gets really wild. Please consider Redditor ImASexyFashionCactus' post:

And ImASexyFashionCactus' hypothesis only gets better from there. Be sure to check it out in its entirety.

Theory #2: Spencer Has A Twin And...


...Spencer has been hiding since the time jump. And the Spencer we’ve seen since the show flashed forward isn’t actually Spencer, but Spencer’s secret twin. Redditor Fadevisitor wrote,

Oh, that is dark. I mean, most of these theories are dark, but the thought of the real Spencer waiting in the bathroom while a grieving Toby hooks up with Spencer's twin gives me the willies.

Theory #3: Spencer Has A Twin And...


...Spencer's twin is actually the Spencer that was on the show before things flashed forward. Take it away, Redditor happilyhastings:

My head just exploded.

Theory #4: Spencer Has A Twin And...


...It’s Bethany Young. Oh, and she killed the real Spencer. I'll let Redditor MaybeBabyToby take it from here:


Theory #5: Spencer Has Multiple Personality Disorder


Redditor bladehider posited,

If this is the case, I hope the series handles it as respectfully as possible.

Theory #6: Spencer’s Sister, Melissa, Has A Twin


OK, this one is more about Melissa than it is about Spencer, but it’s Spencer-adjacent enough. Please consider the following from Redditor MelissAisAD:


Theory #7: Bethany Young Got A Face Transplant To Look Like Spencer


Redditor J2thK theorized, “What if it’s not a twin but a face transplant. Like in that John Travolta movie. AD has had a face transplant to look like someone else.”

And Redditor covermaker replied, “Yeah, Bethany lost her face in the Jenna Thing fire and got Spencer's face.”

Oh, my gosh. If PLL goes full Face/Off on us, I will fall off my couch and log roll around my living room until I fall asleep.

Theory #8: A.D. Has Spencer’s Receipt


In a moment of panic, Caleb and Hannah flooded the Radley’s storage closet before they could locate Spencer's receipt. Er, the Spencer and "Rollins" receipt. That won’t come back to haunt the Liars, right?

Here’s a theory from Redditor snozzleberriess:

Oh, totally. I’d bet money that A.D. will use Chekov’s receipt against Spencer. Unless, of course, Spencer is A.D. Or unless Spencer is actually Beth-A.D. Young wearing Spencer's face. Oh, man. I'm still not over the Face/Off theory.  I may never be over the Face/Off theory. Forever rooting for the Face/Off theory.
