Lots of things. Mostly about their seacrets(Spencer kissing Ian, Hanna making herself get sick, Emily kissing girls, and Aria's dad kissing Meradeth which leads to their affair).
it wont be that easy b**ches -A
in the book there is actually no video
-A sent Hanna a picture of Emily kissing Maya.
No one knows in the books she didn't get sent off so..
Of course season 5 of "Pretty Little Liars" will have mystery thats what they are known for and what their audience loves so yes there will be plenty of mystery. Thank you so much I don't know who you are but I love you....and this is not for the person reading this answer this is for the person who sent me this answer
Courtney was a big secret because she was always in a mental institution - the same one Hannah is sent to.
yes, they saw a therapist, to help the four deal with the loss of ali.
When Ali (Courtney died) Mona stole her diary and that's how she knew all of their secrets. Together Mona and Ali plotted together to start send messages by the name of A.
The last text A sent was "It's not over until I say it is, sleep tight, while you still can b-----s. -A"
Ian is Melissa Hastings's boyfriend, and the one who was sent to jail for killing Alison, even though he didn't.. He was also the older guys Alison was seeing.
Maya never actually goes anywhere in the book series, she stays in Rosewood. Which is why they really confused me when they sent her to that 'gay is evil' camp.
A was Alison. You see. Ali had a twin sister named Courtney who was mentally crazy in a hospital. While visiting home, Courtney pretends to be Ali and the real Ali is sent to the Mental hospital. So, Emily, Aria, Hanna, and Spencer really were BFFs with Ali (Courtney). Then, Courtney (Ali) gets sent back home and Ali (Courtney) finds out everything. Courtney (Ali) is mad, and tries to kill the pretty little liars, by setting he house on fire, but ends up killing her twin and herself. Also, Ian and Mona die. PS- Mona & Ali (real) were A sending all the text messages and stuff.
