I mean, Paige's haircut alone was less believable than Mona being a mastermind.

STILL ON THE CASE

Spencer: "So then is this some kind of payback? Because we let Ali treat you like that?"
Mona: "I keep telling you guys, I don't care about Ali! Easier to forgive an enemy, don't you listen? It's because you bitches took Hanna away!"
Spencer: "Mona, you nutcase, she is still your best friend and staunchest ally! Don't you know how annoying the rest of us find you? She sticks up for you constantly! You drove Caleb out of state, and she forgave you. My God!"
Mona: "I cannot hear you. For once, I am not listening to words you are saying."

Spencer: "Okay, so A always has a plan. What's the plan now?"
Mona, verbatim: "Yes. She does."
Spencer: "What happens if I don't join the Team?"
Mona: "I shoot you with your dad's gun. When Ali left, it pulled you guys apart. It'll be the same if you go away too."

First of all, Spencer's right: We're way beyond that point. Secondly, I'm still confused as to the timeframe here. And third of all, holy motherlode of clues. Is Mona referring to herself as "she," or is she referring to A+? Does Spencer not hear how they keep talking about the A-Team as a group you can join, or does she think Mona just means Team Spona? Did Ali "leave" or was she murdered, and if so, does Mona really think murdering Spencer is going to make Hanna be her friend? Which she already is?

I mean, I know that last one, which is that Mona's been playing us since the show started, but it's still really sad to think that she had exactly what she wanted, and just couldn't help herself from secretly hurting Hanna anyway. All of a sudden, it makes total sense why Hanna always bore the brunt. I thought it was because Ali's Ghost wanted her to become the strongest -- which is how it worked out -- but now we find that it's also because she hurt Mona so terribly bad that it made Alison look like nothing. As if Mona and Hanna's transformation into beautiful bitches, during that lost year, was all part of the plot too. That Mona got her Teenage Popularity wish, and the whole thing was just a mean lie by the time she got it.
