Talk:Pretty Little Liars (Book series)/@comment-117.192.17.114-20130615160330

ok i have a question:

so mellisa finds out that alison and courtney didnt have any sort of communication and and alison was sent away before courtney became frends with the liars. So then how did alison know about the liars secret when she came back and pretended to be courney? like for example emily kissing courtney... she kisses emily again and says she had always wanted to do it again... but how did she know that?
