This 'Pretty Little Liars' Theory Says Caleb Is A.D. And It Makes Too Much Sense


We're getting soooooo close to the big series finale of Pretty Little Liars, and the one question that every fan is still trying to figure out is who the hell A.D. could be.

There have been countless theories about who A.D. is, and what makes the mystery so difficult to figure out is that they all seem to make sense. I mean, once you read the theories, A.D. could totally be Mona, or it could be Ezra, or Melissa, or heck, it could even be Spencer's long-lost twin!

Well, it's time to add yet another suspect to your ever-growing A.D. list: Caleb. That's right — a new theory points to the tech-savvy aid to the Liars as the person who is actually behind all the mayhem.


The theory, posted to the PLL fandom wiki, posits that Caleb is actually Charles, which in turn also makes him A.D. Basically, it states that Caleb's childhood in foster care could easily line up with Charles' past, and the fact that Caleb was housemates with Charles' best friend Lucas adds further proof.

The poster also points out that A.D.'s game seems to obsessively target Hanna, which could be because we know Hanna and Caleb broke up in the 5-year time jump. Check out the full theory below:

Theory in progress Charles is Caleb who is Bethany's half-brother. Mrs D. adopted him because was having an affair with his dad (so was Mary) and done it as a favor. Caleb's story says he was put into foster care at age 5 but that was actually when he was sent to Radley for the bathtub incident. When Mrs. D took Bethany to the horse stables it was because she knew her father worked there, Jamie Doyle also Caleb's father. Bethany is Mary's daughter and Spencer's sister (not twin) however they look a lot alike. Caleb was housemates with Lucas who happens to be Charles best friend. The camp they met for "troubled boys" had to do with them crossdressing or something similar that's why Ali called Lucas Hermie. He was then taken from Radley and put into foster care after Toby's mom's death. That is the pictures the Bethany drew. He has the tech abilities to build the game and pull off the things AD does. Hannah is getting punished the most in the game for leaving him during the 5 year jump as we know Charles is very obsessive. We don't know much about his life prior to rosewood which could be Charles' childhood in foster and Radley. He targets Allison for how she treated Lucas. Would have easy access to Lucas loft since Hannah was staying there to take the graphic novel. Cece became obsessed with the game from Mona and Charles took advantage of this and her mental stability and used her knowing her relation to Mary and Ali. Wren was Charles doctor and Charles has some sort of dirt on him that is forcing him to keep things a secret and use as a pawn as well. We know that one characters age is different then what we think and I think that it would be Caleb's. AD stands for Arcturus Doyle. Arcturus being the character in the graphic novel Doyle being his father's last name.

It's actually a pretty convincing theory, especially considering Caleb is definitely the most technologically competent character on the show, and he has the money to do all the things that A.D. has been capable of.

The one possible hole that a commenter points out is Caleb seems too young to be Charles. Then again, Caleb could have been lying about his age this whole time and just is lucky enough to look much younger than he is. Hey, weirder things have happened on this show.

We'll just have to wait until the big finale next week to find out for sure!
