Before you begin reading, let me warn you that this post will contain spoilers about the Pretty Little Liars Season 2 Finale. I strongly advise that you stop reading now if you do not wish to know the identity of “A” (oh, but do drop by again after you’ve seen the episode…).

Tonight one of life’s most pondering questions was answered. (No, not whether O.J. Simpson was guilty or how do they actually get the caramel in a Caramilk bar). Tonight on Pretty Little Liars (Season 2, Episode 25, umAsked), the identity of “A” was revealed. And…it’s Mona.

Before I share my thoughts, a quick recap of the episode. Basically, the girls are invited by “A” to the Rosewood Junior League Masquerade Ball. Before the ball, they end up at The Lost Woods as the Bates Motel where “Vivian Darkbloom” rented a room the night before she was murdered. Over scenes of a dark, rainy night, it appears “A” is in the room next door spying on the girls. Fast forward to the Masquerade Ball: following ‘surprise’ appearances by Caleb and Ezra, Spencer makes a fascinating discovery: Vivian was not at the motel hiding from “A”, but instead she was searching for “A”, and it hits Spencer that the room next to the one the girls and Alison had stayed in for a night was actually rented by someone (“A”!). Spencer, who normally does not tell Mona anything, decides now is the time for her and Mona to become best buddies. Batman and sidekick Mona travel to the motel and enter the rented room: BOOM! “A’s” lair is revealed: creepy dolls, newspaper clippings, and some freakish clown head fill the room. Now here’s the kicker. While snooping, Mona offers Spencer a piece of gum who politely declines until she sees the SAME gum wrapper in Alison’s diary which is in “A’s” lair. (Are you keeping up with me still?)

Spencer then decides to take Mona up on the gum offer. Mona races to her car to get the promised gum. BOOM #2. Mona’s back and somehow in 10 seconds has changed from her masquerade gown to black sweats, hoodie and all. Mona ends up whacking Spencer and fast forward to a scene of the two speeding down some deserted area. Spencer manages to get Aria and the girls on the phone who overhear her and Mona chatting and learn about their whereabouts. Minutes later, the remaining girls have caught up to Mona and Spencer. Mona has somehow trampled down the woods, but low and behold, she’s alive. However, she’s to have a personality disorder and placed in an institution (this is where Dr. Sullivan’s has magically returned after Toby apparently called her. She explains she disappeared because her son was threatened). ” In a voiceover, we hear Mona warn the girls that they are in a place exactly as “we wanted”. The episode ends with Mona receiving a visitor, where she says: “I did everything you asked me to””. And in case you’re wondering who it is that dies in this episode, there’s a brief scene near the end where it’s revealed that Maya is apparently dead.

Many questions remain unanswered: who killed Maya? Who is the “A” team? Who exactly killed Allison? Who was Jenna speaking with? Who was a mystery girl in a black swan dress? Who visited Mona at the end? And the one that really boggles my mind: how did Toby know where Dr. Sullivan was? (Did I miss something here??) And of course there are question marks around Garrett and Melissa.

My personal thoughts? Am I surprised? No. I suspected Mona was “A” quite a few episodes ago (the episode where they go back to when Jenna and Mona meet at a pool party gave me an inkling). However, I heard Mona was “A” in the Pretty Little Liars books and the producers would not be following the books; therefore I felt Mona was no longer “A”. Am I disappointed? Slightly. But then again, I feel I would have been a bit disappointed no matter what direction they went in. What I do know is I will definitely be watching when Pretty Little Liars returns. Catch the Season 3 premiere on Tuesday, June 5.
