If you don't remember, he was the pale child who told the Liars that back when Alison (Sasha Pieterse) visited the doll store, a man and woman with dark hair also came in, and had ill intentions towards Ali.
We've never gotten a definitive answer on who the couple was, and now that we know Mona (Janel Parrish) had a male teammate in Toby (Keegan Allen), some fans are wondering if they're the guilty party.

A fan recently asked PLL writer Joseph Dougherty if we'll ever find out who the couple was. He replied, "I thought we already kind of knew...assuming [Seth] was telling the truth." Um … we do? We have some theories, but we don't remember ever getting a straight answer on this.
The fan then asked the next logical question: "So Mona & Toby were the couple?" But Joseph responded, "Mona and Toby were never a couple the way I think you mean...at least the way I figure it."
So does that mean they weren't the ones at the doll shop (since it was implied that couple was together together)? Or is that just a mislead? Are we forgetting something here?
What do you make of Joseph's tweets? Do you think the answer to this mystery is as clear as Joseph seems to suggest?
