PLL Episode 6x07 "O Brother, Where Art Thou"
Clues in the Episode that Aria is A
Mike finds Aria cleaning out her doll collection. Apparently after years of obsessing over dolls she has decided she needs a new subject to focus on. Mike brings Mona a basket of Aria's old dolls that are all bloody and tied up. Mona asks if she was using them to photograph what happened to them and he says Yes. How does Aria even know what happened to all the girls in the dollhouse since she refused to talk to anyone about their experience. Has Aria always played out A's work with her dolls and photographing them?
While Aria suggested that they leave the microchips A planted in and Spencer temporarily agrees thinking they can trick charles, she and Hanna have second thoughts and do some research on how to remove the microchips.
While Aria is encouraging the girls to contact Leslie, that is not the case for Charles. She seems to now want to go to the police about Charles knowing that he would be tipped off as soon as the police were involved. As the plan to trap Charles starts to take motion, we see Aria almost call 911 then stop when interrupted by Emily. Funny how this is the first time I remember Aria being the one who wants to go to the police. Usually she is the one talking the girls out of going to the police. While the other girls want to try to trap Charles to force some answers and find the truth, Aria does not seem to be on board with that plan . Turns out Ali calls the police and Charles manages to get away again.
At the end of the episode, life seems to be falling apart for all of the liars except for Aria. Jason and Ally feel guilty over missing an opportunity to find Charles, Emily is upset Sarah is moving out, Hanna is upset her mother insists on using the tainted scholarship money, and Spencer and Toby are a mess after he Charles debacle with Spencer's drugged candy. However, Aria gets the good news that she won the photography contest.
