Woah ok everyone, A i not Mona. Get that out of your minds. Mona is a puppet of A, it is clearly obvious. Get all that twin BS out of your heads, trust the writers, they said that Mona wont be A or a Twin. So there wont be, they are not stupid enought to lie (even if its PLL) and loose many of their fans. I think, stay with me here, SPENCER is A. She is the master controller that her pupputs dont even know who she is. Firstly, in the beginning of the episode when she says "my mom knows the joury and it was Jenna" who dropped the 5th page off. No Jenna gavee it to TOBY, how could Jenna drop it off. Wouldnt it be Toby, and why is Spencer saying that. Plus doesnt anyone think its weird that Dr. Sullivan just randomly popped in and who was the first person to bring her up...Spencer. When Hanna asked "why are we lying?" Spencer said "so we dont end up like Dr. Sullivan." Wth so random. Then, Spencer is the one who goes to A's lair and she is going through everything, She quickly realizes the supposed A is Mona...random...from a piece of gum and she says "You never called Hanna" yet Hannah saw the girl in the black swan dress...interseting. Also, Spencer asks Mona "Doesnt A always have a plan?" to which Mona responds "Yes...SHE does" almost as if she doesnt know who it is and Spencer does...because SHE has a plan. And also, that whole creepy hide and seek moment may not have pointed to Spencer...but it was creepy...also A is apparantly a genius and when Emily says that Spencer walks in and "takes offence..." hmm interesting. Now this is a theory but hey :)
Anyway, on a side note: when the Liars were driving to the resort, someone passed them by screaming...i think that was MAYA as if you pause, you can see this is a person...who has a long coat...which is brown just like Maya had before. So A kidnapped Maya and held her captive.
Did anyone notice that when Hanna was in the shower, a phone rang right when Emily called Maya...meaning that was Maya's phone...so A is Maya or had killed Maya? There are many more things you can notice if you rewatch the episode...Plus, the wallpaper hole...did you notice when "A" was looking through the wall it had a picture frame and GREEN wallpaper...but when Spencer and Mona entered the room...where was the green wallpaper...how do you redocorate like that...meaning that there was the TRUE A looking from an unknown location...
