Just when you thought "Pretty Little Liars" couldn't be any more complex, the producers throw in another interesting idea for the fans to mull over. When Byron Montgomery's (Chad Lowe) former lover, Meredith (Amanda Schull), was last in Rosewood, it seemed as though we'd finally seen the last of her. However, Season 3, Episode 2 proved everyone wrong. Meredith applied for a teaching position at Rosewood High, and when "A" left a gift in Aria's (Lucy Hale) locker, a world of new possibilities opened up. Let's take a look at the idea that Meredith and Ali (Sasha Pieterse) were working together.
Ali and Aria spotted Byron kissing Meredith.
In a Season 1 flashback, Ali and Aria just happened to stumble across Byron and Meredith kissing in his car down a side street. A side street Ali pulled Aria into while trying to run away from Mona (Janel Parrish). Sure, coincidences happen all the time, but where Ali is concerned, there is no such thing as a coincidence. Ali and Meredith could have set up that sighting in order to start the chain of events that should have led to Ella (Holly Marie Combs) and Byron's divorce.
Ali forced Aria to tell Ella the truth.
When Ali was alive, she tried to force Aria to tell her mother about Byron's affair. She didn't, she covered it up instead. But a year later, "A" revealed Byron's secret in a letter to Ella after Ella and Meredith had started to become friends. Had Meredith not been in town when it happened, it might not have been quite as suspicious, but for "A," timing is everything. It seems likely that fanning the flames of the affair was a pre-conceived idea, meant to drive Byron and Ella apart.
Ali could have planted the earrings.
In the episode, "Blood Is The New Black," a flashback showed Aria and Ali snooping in Byron's office for clues that his affair was really over. While Aria was searching his desk, Ali produced an earring. We didn't see her finding it, we just saw her holding it. This reeks of a set-up with Ali having the earrings in her pocket to place on the scene when Aria wasn't looking. When one of the earrings reappeared in the present, and Aria gave it back to Meredith, Meredith said it wasn't hers. This leaves two options. Byron was sleeping with more than one of his students or co-workers, or Ali planted them. Devious as she was, the latter is most likely.
"A" pushed Meredith and Byron closer by forcing Aria to apologize.
Aria received a text from "A" telling her she needed to apologize for trashing her father's office and blaming it on Meredith the day she and Ali found the earring. To her credit, Aria stepped up, but as a direct result, Byron and Meredith arranged a lunch date. This is bad news for Aria, but definitely something Ali, or "A," could have predicted or even planned.
There are several more questions that stem from these speculations. Most obviously, if Ali and Meredith are, or were, working together, is Ali really dead? Also, was Mona working with Ali, too? It was no secret that Mona wanted to be popular and would have done anything to get closer to her, even if it meant causing pain to someone else. Whatever the truth is, it can't be an accident that Meredith applied for a job at Rosewood High. She is trying to get Byron back, and with or without Ali's help, she is going to be trouble.
